Flowserve Durco Mark 3 Shafts and Sleeves
Shaft Choices
Composite: a steel shaft end-to-end with an integral sleeve of DC8, SD77 high silicon iron, ceramic (alumina or zirconia)
Friction-Welded: a steel power end friction welded to a solid alloy wet end
Flowserve Durco shafts and sleeves are designed to improve pump reliability.
Solid: steel end-to-end or stainless alloy end-to-end
Shaft Material Choices Standard: investment cast or high alloy bar stock available in a wide range of materials, including proprietary DC8 and SD77 wet ends. DC8 and SD77 offer superior corrosion resistance and hardness to minimize shaft fret corrosion and maximize shaft wet end performance. • DC8 – a cobalt base alloy with chromium and molybdenum • SD77 – or Superchlor is a high silicon iron alloy Flowserve recommends the use of solid shafts rather than shaft sleeves to reduce the harmful effects of deflection and vibration. Shaft sleeves may simplify maintenance but solid shafts reduce it.

Hook Sleeve: a steel shaft end-to-end or a steel power end friction-welded to a stainless wet end accommodating a hook sleeve
➀ ➁ ➂
Radiused “sled-runner” keyways improve strength at this stress point. Offset keyways aid shaft balance. Alloy identification on every shaft and sleeve ensures that the right parts go in every time.
➃ ➄
➇
Large radii fillets add strength. Accurate machining under bearings ensures perfect bearing fits without vibration or hot running.
➅
Steel power ends handle higher horsepower loads than stainless.
➈
➆
Run-out of < 0.03 mm (0.001 in) at mechanical seal allows seal faces to run true. Critical surfaces ground to a surface finish of 0.4 micron (16 µin) ensure the secondary sealing ability of mechanical seals.
Minimally radiused edges ensure full contact with impeller for reduced run-out.

ANSI Pump and Enhancements Special Shaft and Sleeve Alloys There are three important considerations in the selection of a suitable shaft material for a pump application: • corrosion resistance • wear resistance, and • shock resistance – both thermal and mechanical. To meet these criteria, Flowserve developed DC8 specifically as a shaft sleeve material.
Exclusive DC8 Composite Shaft DC8 is an ideal sleeve material because of its optimum combination of strength (tensile strength equals 4136 bar [60,000 psi]), hardness (Brinell of 300), and corrosion resistance (superior to Alloy 20 in many cases).
Shaft is machined as an integral unit after DC8 alloy is permanently affixed. Single machining tolerance means better concentricity and lower runout.
Fully contained PTFE encased silicone O-ring protects shaft thread.

Flowserve Durco Mark 3 Heavy-Duty Shafts and Bearings
Unique External Micrometer Impeller Adjustment It reduces maintenance time and, most importantly, is precisely accurate.
The Heart of the Pump: Shaft and Bearing Design Flowserve offers the largest shaft and bearing components available in standard ANSI pumps. The following comparison of a Flowserve Durco Group 2 power end with that of a major competitor demonstrates the benefits of heavy-duty design. Flowserve Durco bearings are designed to last up to 61% longer.

Bearings (see Table 1) Greater load handling rating means extended MTBPM. Extended bearing life comparison is the ratio of the load ratings to the third power, or: 13 400 3 I.B.= 11 900 =1.43 (+43%) 19 200 3 O.B.= 16 400 =1.61 (+61%) 43-252% greater stiffness, indicated by lower index numbers, results in longer MTBPM.

Shafts (see Table 2) Solid shafts are recommended over shaft sleeves because they reduce the harmful effects of deflection and vibration. While shaft sleeves may simplify maintenance, solid shafts reduce it. Proper selection of wet end materials of construction and mechanical seal design offset positive features of the shaft sleeve option.

Simply loosen the set screws. Using a wrench rotate the bearing carrier counterclockwise until the impeller lightly touches the rear cover plate.
Select the impeller setting. Each notch on the carrier ring represents exactly 0.10 mm (0.004 in) of clearance. For an impeller setting of 0.5 mm (0.020 in) count five notches counterclockwise.
The formula I=L3/D4 offers an index of deflection to compare pump designs where: I = index of deflection L = length of shaft overhang from bearing D = rigid shaft diameter Note: The Deflection Index provides an approximate comparison of shaft stiffness. A detailed analysis should be made to determine actual shaft deflection.
Move the bearing carrier clockwise the selected number of notches. Tighten the setscrews and check the impeller clearance with the feeler gauge.

The following shaft deflection curves are based on the maximum size reverse vane impeller pumping 1.0 specific gravity liquid. Shaft deflection varies directly with specific gravity and by the square of the pump speed. The graphs show that as flow is increased to BEP, the deflection decreases. The measurement given is deflection at the face of the seal chamber. Flowserve recommends the use of solid shafts rather than shaft sleeves to reduce the harmful effects of deflection and vibration. Shaft sleeves may simplify maintenance but solid shafts reduce it.

SealSentry FM Series Seal Chambers
Advanced FM SealSentry Design Technology • Self-Flushing • Self-Venting • Self-Draining Seal life is extended due to superior purging of heat, solids and vapors. Single seals can often be selected where dual seals or external flush and throat bushing combinations had been used, such as on solids, slurry and liquor services. Flush plans 11, 32, 52, 53, etc. can be eliminated. Costs are reduced. Pump reliability is increased.
The FM (Flow Modifiers) series features an enlarged, tapered bore with cast-in flow modifiers
Maximizing seal life involves proper selection of the seal chamber and seal and gland combination. Generally, the seal faces should be located directly in the flush path. For SealSentry video and proof of performance contact the local Flowserve sales office.
Flow Modifiers Extend Mechanical Seal MTBPM • Flow modifiers redirect flow from circumferential to axial • Balanced flow with low pressure drop in the chamber helps keep solids in suspension, minimizing erosive characteristics of the process • A mechanical seal creates a centrifuging action away from its parts and into the returning flow path of the process liquid • Solids and slurry merge in the returning flow path and are flushed out of the seal chamber

SealSentry FM Series Seal Chamber
Flowserve Durco superior self-flushing seal chambers will: • Extend seal MTBPM • Improve pump reliability • Reduce costs
SealSentry FM – Opportunities
Results and Comments
The SealSentry FM provides improved internal seal chamber flush, with better solids handling, superior heat dissipation and vapor purging. These features extend mechanical seal life in both single, internal and the process side seal of dual seals.
On most applications, a bypass line such as ANSI Plan 11, which can be subject to failure, can be eliminated. Save on capital and power costs and improve system reliability while extending seal MTBPM.
For best performance, select seals and glands that locate the process side seal faces directly in the flush path.
However, a bypass flush is recommended when negative suction pressures or self-priming pumps are applied. Note: Single external seals are discouraged particularly if solids, slurry, or liquor may be present, regardless of flush mechanism.
Save on capital, power, and perhaps evaporation costs and improve On most applications the FM self-flush can eliminate the need for an external flush such as ANSI Plans 11 and 32. system reliability while extending seal MTBPM.
On most other applications, single seals without a bypass flush may be applied. Save on capital, avoid product contamination, and improve system reliability.
SealSentry FM improves internal process seal flush and allows consideration of single seals with potentially no other flush required.
On some applications, single seals with a quench may be preferred. Save on capital cost, reduce contamination, and improve system reliability while extending seal MTBPM.
Note: Abrasive services require careful consideration of the concentration and hardness of the abrasive. Pump and seal metallurgy, speed, and seal selection should be reviewed with the manufacturer.
12
When a dual seal is required, such as toxic or environmental applications, seal life will be extended with SealSentry’s improved self-flush. Longer seal MTBPM means cost savings.
Dual seals are often specified on solids, slurry, and liquor services due to difficulties in properly flushing single seals. External flush on these dual seals adequately lubricates internal/external seal faces, but seal life can be reduced by process buildup and temperature rise on the internal side seal. This is caused by poor process circulation.
When extremely abrasive and high concentration slurries exist, dual seals that isolate the seal chamber may be preferred.

SealSentry Types and Recommendations FML
Oversized, tapered bore with 8 specially shaped and evenly spaced cast-in flow modifiers. Designed for seals with large gland bolt and gasket circles.
• Single internal cartridge seals • Dual internal/external cartridge seals • Single internal component seals with flexibly mounted seats* • Dual internal “true” tandem cartridge seals Note: Bypass flush to internal seal normally not required. Barrier fluid or external flush may apply to dual seals (Plans 52, 53, etc.).
FMS
Same chamber design as FML but accommodates seals with small gland bolt and gasket circles.
Same seal and flush plan recommendations as for FML. Single seals with all types of seat mounting configurations can be installed. FMS design is provided for the convenience of customers with seal standards that include small glands. Secondary to the FML, Flowserve recommends the FMS.*
FMI
Same chamber design as FMS, but includes a cast-in integral gland.
• Single internal, flexibly mounted seals. Uses sleeve for seal setting and fast installation • “Sanitary-type” applications. Less prone to bacteria build up Note: Bypass flush is normally not required.
CBL
Oversized, cylindrical step bore design for seals with large gland bolt and gasket circles.
• Dual internal component seals. Isolates the seal chamber from the process. Allows less expensive seal materials. Recommended in tough slurry applications Note: Use External Flush Plan 54. Others (i.e., Plans 52, 53) not recommended without close tolerance pumping mechanism.
(Preferred seal chamber design for nearly all applications)
• Single internal component or cartridge seals when applied with a throat bushing. Usually selected to increase stuffing box pressure above the vapor pressure to avoid cavitation, etc. Note: Applied with Plan 11, etc.
CBS
Cylindrical bore design for packing arrangements and conventional seals with small gland bolt and gasket circles.
*All seal selections perform best when the faces are located directly within the flush path, particularly if solids, liquors, or slurries are present. Component seals with clamped seat gland designs locate the seal faces reasonably well. Flexibly mounted seat glands should include the vent and drain option to better locate the seal faces. The FML is always the first-choice chamber for maximum self-flush path benefits.
• Dual internal component seals. Isolates the seal chamber from the process. Allows less expensive seal materials. Recommended in tough slurry applications. Allows for thermal convection type flush plans; however, pumping ring devices are recommended Note: External Flush Plans 52, 53, 54 • Single internal component or cartridge seals when applied with a throat bushing. Usually selected to increase stuffing box pressure above the vapor pressure to avoid cavitation, etc. • Usually preferred over the CBL when jacketing is selected for increased effectiveness in cooling or heating Note: Applied with Plan 11, etc.

DurcoShield™ Pump Safety Accessory
DurcoShield is easy to install or to remove. Simply spread the shield apart... fit around the bearing housing adapter... and snap into place. The spring-like tension holds the shield firmly in place. • Its transparency permits visual inspection of the seal area • Optionally available in PVDF • Applications from -57°C (-70°F) to 149°C (300°F) • Available for Mark 2, Mark 3 and Chemstar® pumps
This splash and shaft guard is a one-piece shield that envelopes the open areas between the bearing housing and the casing. • Fluid spray from a malfunctioning seal is deflected by the shield • Provides protection from the rotating shaft in the area of the mechanical seal as required by safety regulations of many countries, including the USA’s OSHA Section 29 CFR 1910 and EU Machinery Directory Protection from the potential dangers of: • Process fluid spray • Rotating shaft and seal components
Contact your local Flowserve representative today for complete information.
Slots or holes to accommodate seal support piping/tubing can be easily located and drilled or cut.
This device is not a containment system, nor a seal backup system. It is a limited protection device. It will reduce, but not eliminate, the probability of injury. PATENT PENDING

Impeller Options
Flowserve Durco reverse vane impellers deliver unequalled efficiency and performance. This exclusive impeller design extends bearing and seal life. Low, Predictable Seal Chamber Pressure and thrust loads resulting from back vane pumping action and balance holes Low Required NPSH, lowest overall of any standard pump Rear Cover Plate Wear Surface as the flow path exits the rear of the impeller, placing abrasive wear on the rear cover rather than the more expensive casing
Exclusive Reverse Vane Impeller with balance holes offers important performance enhancing, maintenance reducing advantages.
In Shop Impeller Adjustment with the only impeller design that takes full advantage of the back pull out feature. Since the critical running clearance is set between the rear of the impeller and the rear cover plate, both impeller and mechanical seal settings can be done in the shop, “on the bench,” instead of under adverse field conditions Repeatable Performance Assurance with the only impeller design that offers repeatability in seal chamber pressure and bearing thrust loads
Front Vane Open Style Impeller is fully interchangeable with the reverse vane impeller. Excellent choice for stringy and certain applications requiring high shear against the casing.
In-shop Impeller Adjustment…Practical and Productive!
For Low Flow and/or High Head Applications see page 18
Low predictable seal chamber pressure means longer seal life Clearance is set to the rear cover in the shop – not with casing which is left in the piping
Lowest overall required NPSH of any standard pump
Rear cover wear surface versus casing means lower replacement parts costs
16
Note: Recessed impeller pumps offer excellent solids handling capabilities. See pages 52-55 for details.

Reverse Vane Impeller and Repeatable Performance
Only a Flowserve Durco reverse vane impeller offers repeatable performance after wear and impeller adjustment.
An impeller cannot be adjusted to two locations.
Performance Life Cycle: Flowserve Durco Reverse Vane Impeller with Balance Holes
Performance Life Cycle: Front Vane Open Style Impeller with Pump Out Vanes
Effects of Wear • Thrust loads decrease as seal chamber gap widens • Chamber pressure increases as gap widens Effects of Impeller Adjustment to Seal Chamber • Original pressures and loads re-established after adjustment • Repeatable MTBPM cycle life The Reverse Vane Impeller has only one set of pumping vanes and one critical tolerance location – between the impeller and rear cover – to establish: • Performance • Efficiencies • Seal chamber pressures (i.e., mechanical seal MTBPM) • Thrust/axial loads (i.e., bearing life)
Seal and bearing life are reduced due to increased loads after wear and maintenance adjustment.
Effects of Wear • Thrust loads increase as seal chamber gap widens • Chamber pressure increases as gap widens Effects of Impeller Adjustment to Casing • Chamber pressures and bearing loads increase after each adjustment • Non-repeatable MTBPM cycle life

Flowserve Durco Mark 3 Specifications For Low and High Temperature Services
Centerline Mounted Casing
With special attention to materials and component options Mark 3 pumps can be used to handle liquids ranging in temperature from as low as -130°C (-200°F) to as high as 370°C (700°F). It is always essential that the pressure and temperature of the application never exceed the pressure/temperature limits of the pump. These limits may be found in the chart on page 30 of this bulletin. Operation at either low or high temperatures could require modification of the standard pump design to provide strength of materials for pressure containment and resistance to thermal shock, a method for cooling or heating pump components, mechanical seal protection, special gaskets, and/ or maintenance of pump/motor shaft alignment. The Ultralign C-flange motor adapter is recommended on any application with temperature fluctuations of more than 38°C (100°F).
Low Temperature Applications Special recommendations for temperatures < -29°C (-20°F).
Casing Stainless steel alloys with jacketing. Seal Chamber Stainless steel with jacketing. SealSentry designs with customized seal and flush plan as required by the application. Shaft and Sleeve Stainless steel alloy with optional replaceable alloy sleeves. Friction welded 1144/316 (ZH) is recommended. Gaskets Temperature/liquid compatible. Coupling Flexible member spacer-type. Power End Stainless steel bearing housing and adapter. ANSI 3A with synthetic lubricant recommended. High Temperature Modifications Special recommendations for temperatures > 149°C (300°F).
Bearing Housing ANSI 3A power end is recommended. For temperatures > 177°C (350°F) oil cooling system is recommended. For temperatures > 260°C (500°F), stainless steel bearing housings are required on Group 1 pumps and stainless steel adapters are required on Groups 2 and 3 pumps.
Jacketed SealSentry Seal Chambers Ultralign C-Flange Motor Adapter (See page 20)
Jacketed standard bore (CBS) is recommended when cooling the seal chamber is the objective.
® Grafoil is a registered trademark of Union Carbide Corporation
Rear Cover For temperatures > 177°C (350°F) jacketing is recommended. In addition, CBL or CBS with throat bushing is recommended to allow cooling jacket to be more effective. Shaft Friction welded 1144/316 (ZH) is recommended.
Cooling Coil Oil Temperature Control
Jacketed Casing
Casing For heat transfer liquids, recommend using DIN/PN40 (ANSI Class 300) flanges. Temperatures > 149°C (300°F) require Grafoil ® impeller and casing gaskets. If Ultralign heavy-duty rigid design C-flange adapter is not used and temperature is > 177°C (350°F), then centerline mounting of the casing with cooling of mounting legs is recommended. If Ultralign is used, centerline mounting is not recommended until temperature exceeds 260°C (500°F).
Jacketed FM chamber is preferred when protection of the process temperature is important.
Baseplate Rigid reinforced base with stilt/spring mounting. Motor Mounting Ultralign C-flange adapter is recommended on Groups 1 and 2. Hot alignment is always recommended.

ANSI Pump and Enhancements Flowserve offers a family of five (5) types of pre-engineered baseplate designs to extend MTBPM and reduce costs. Reducing internal stress and vibration extends MTBPM of pump/motor packages Pump users specify rigid baseplate designs to: • Provide torsional lateral and longitudinal rigidity • Improve vibration dampening through greater mass and design stiffness • Protect against transit damage • Resist twisting during installation • Maintain designed-in shaft alignment • Reduce installation and shaft alignment time • Reduce diaphragming or separation from grout • Improve pump/motor/seal MTBPM • Reduce total life cycle pump/motor/seal costs BaseLine can handle the stress. Rigid design begins with thick plate construction. Metal baseplate sizes: • 139 to 258 feature 13 mm (1/2 in) steel plate construction • 264 to 280 feature 16 mm (5/8 in) steel plate construction • 368 to 398 feature 19 mm (3/4 in) steel plate construction Polybase baseplates are constructed of 76 mm (3 in) to 102 mm (4 in) solid polymer concrete. Baseplate Types B, C, D and E are reinforced with added structural support for improved rigidity.
22
Baseplates Provide the Backbone for Extended MTBPM The test stand provided three corner support of the ungrouted baseplates. The addition of weights on the unsupported fourth corner caused baseplate
distortion. This distortion resulted in measurable shaft movement that can cause problems with field installations and negatively affect MTBPM. The twist test is a means of comparing rigid baseplate designs. Correctly installed rigid baseplates should not experience these twist effects. For more information about the results of baseplate testing contact the local Flowserve sales representative. Baseplate Rigidity Test – Twist Mode A

Flowserve Durco Solid Polymer Concrete Polybase™
• Polybase is available with or without catch basin or grout holes • Inserts can be located to accommodate various pump/motor type configurations • Polybloc is available for alternate equipment applications
Type B Foundation or Stilt Mounted Featuring Flowserve Durco Solid Polymer Concrete Polybase™ and Polybloc™ Adjustment System
Polybase • Low installed cost • Superior vibration dampening • Corrosion resistant • Superior resistance to twisting or diaphragming • Designed to be flat • Available with or without catch basin or grout holes • Inserts can be located to mount alternate equipment configuration requirements Solid cast reinforced polymer construction makes Polybase extremely strong and rigid. It easily handles pump and motor loads without flexing problems commonly associated with cast iron or FRP baseplates. Its excellent corrosion resistant properties enable it to outperform and outlast typical cast iron or even steel baseplates.
Vibration Damping Comparison The extraordinary vibration damping characteristics of polymer concrete significantly reduce wear and tear on pumps, seals and motors. Greater dampening characteristics mean easier vibration analysis during preventive maintenance. Vibration damping of polymer concrete versus cast iron

Flowserve Durco Mark 3 Minimum Flow & Fasteners
Flowserve Definition: Minimum continuous stable flow is the lowest flow at which the pump can operate and still conform to the bearing life, shaft deflection and bearing housing vibration limits of ASME B73.1-2001. Minimum continuous thermal flow is the lowest flow at which the pump can operate and still maintain the pumped liquid temperature below that which will have an adverse effect on the pump or seal performance, or on the quality of the pumped liquid.

Technical Data
Flowserve Durco Mark 3 How To Specify Process Pumps
Flowserve Suggests the Following Specifications When Purchasing ANSI Pumps: Design: Shall be of a horizontal, end suction, single stage, centerline discharge, “back pull-out” construction, meeting the design criteria of the ASME B73.1-2001 standard. General: All wetted parts shall be permanently marked with the material of construction. Cast parts shall have a conditional lifetime casting guarantee. Stainless steel parts shall be cast to the ASME A744 standard. Casing: Shall have a fully machined wet face and shall be capable of being foot or centerline mounted. Flange finishes shall conform to ASME/ANSI B16.5 and shall be available in DIN/PN16 or 40 (150 or 300 Class), flat or raised faces. Casing and rear cover plate shall have 3 mm (1/8 in) corrosion allowance.
38
Impeller: Shall be the reverse vane design, and shall be open on the back and shrouded on the front. The impeller clearance shall be set against the rear cover, not the casing, allowing all settings to be done in the maintenance shop, without the casing. The impeller shall maintain low seal chamber pressures, which shall be published on the pump performance curve, and shall be repeatable after maintenance. The impeller clearance shall be set externally. The impeller-toshaft connection shall be a metal-to-metal fit. A silicon O-ring encapsulated in PTFE shall be used to protect the impeller threads. Impeller shall be balanced to ISO 1940 Grade 6.3 criteria. Shaft: Shall be of solid construction to maximize strength and rigidity. The shaft shall consist of a steel power end friction welded to an alloy wet end. Shaft deflection shall not exceed 0.05 mm (0.002 in). The shaft key slot shall be designed with a machined radius “sled runner” edge to provide maximum strength at the coupling. Critical surfaces shall be ground to 0.005 mm (±0.0002 in), maximum roughness at the seal chamber shall be 0.40 µm (16 µin). Rear Cover: Shall be suitable for accepting various seal designs from all major seal manufacturers. Cylindrical bore standard, cylindrical bore oversize, and tapered options shall be available. Tapered options shall include eight evenly spaced, tapered and sloped flow modifying devices integrally cast into the seal chamber. The flow modifiers shall facilitate movement of solids, vapors, and heat away from the mechanical seal. The tapered seal chambers shall be designed
to be self-flushing. For optimum performance the seal and gland shall be selected to locate the seal faces directly in the flush path. Integrally cast jackets shall be available. Bearings: Shall be large, heavyduty, ball bearings. The inboard bearing shall be a single row, deep groove. The outboard shall be double row angular contact, deep groove. An optional duplex angular contact outboard bearing shall be available for high thrust load applications. Both bearings shall be located by a shoulder on the shaft. The inboard bearing shall float in the bearing housing, while the outboard bearing shall be locked in place in the bearing carrier. The bearings shall exceed B10 life of 17,500 hours and allow less than 0.025 mm (0.001 in) end play. Bearing Housing: Shall be sealed to prevent contamination of the lubricant. The oil fill hole at the top of the housing shall be plugged. No vented constant level oiler shall be used. The housing shall be sealed with Inpro VBXX bearing isolators. A magnetic drain plug shall be used. A large easy to read one inch NPT sight glass shall be used. The impeller clearance shall be set by the micrometer
adjustment method. This method shall cause the shaft and impeller to move axially. Indicators shall be cast into the bearing carrier which represent 0.102 mm (0.004 in) of axial impeller travel. This allows accurate impeller clearance to be established externally without the use of measurement devices. The bearing carrier threads shall be protected by two O-rings. Coupling Guard: Shall conform to ASME B15.1 and shall be of the “clamshell” design. It shall extend from the motor to the bearing housing, but shall not be attached to either. The guard shall be bolted to the baseplate. Baseplate: Shall be of a reinforced rigid design and shall conform to the dimension requirements of ASME B73.1-2001.

Mark 3 Sealmatic
Flowserve Durco Mark 3 Sealmatic
Dynamically sealing repeller eliminates the need for conventional mechanical seals. Advanced static seal options are available. Dimensionally interchangeable with all ANSI pumps.
Dynamically Sealing Repeller
The Sealmatic Principle This pump does not leak while running because the Sealmatic design utilizes a repeller, a dynamic sealing device, to evacuate liquid from the seal chamber. This is accomplished by creation of a liquid interface seal in the repeller chamber that prevents leakage along the shaft during operation. For sealing while the pump is stopped, three types of sealing arrangements are offered for maximum application flexibility: Checkmatic end face lip seal arrangement; dry-running end face seal designs; and the packed stuffing box design.
Applications • Tough sealing applications where a flush is impractical • Evaporator service • Continuously running pumps
This family of repellers allows the Sealmatic to be used in applications having a wide range of suction pressures. Hydraulic performance conforms to the Standard Mark 3 reverse vane impeller curves.
A choice of sealing arrangements

The Sealmatic design is also available with unitized selfpriming and recessed impeller pumps. Stopped

Mark 3 Self-Priming
Unitized Self-Priming
Costs less to buy, install and service than submersible pumps. Utilizes the same power end, shaft, seal chamber and impeller as the Standard ANSI Pump. Only the casing is special.
Applications • Sump service • Tank car unloading • Duplex pumping lift stations • Flyash pond transfer • Waste acid transfer • Waste treatment lagoon service

Priming Cycle Cutaway Illustrations 1. Sump Filling, Pump Stopped The casing is shown with the initial prime liquid, which permanently stays in the casing. This serves as the priming liquid necessary to entrain the air contained in the suction line. 2. Pump Start-Up As the impeller spins, the priming liquid entrains air from the suction pipe and is pumped into the air separator/priming tank portion of the casing. In this chamber the air separates from the priming liquid and vents out the discharge while the priming liquid flows through the bypass slot in the bottom of the casing and back into the impeller eye.
As the priming liquid circulates, it re-entrains more air, creating a partial vacuum in the suction line. The sump liquid is then pushed upward by atmospheric pressure. 3. Priming Achievement After the priming cycle has evacuated all of the air from the suction pipe, the sump liquid floods the volute, air separator and priming chamber, and pumping out of the discharge pipe begins. The Unitized Self-Priming is fully primed and now operates exactly as a standard flooded-suction Flowserve Durco pump. 4. Sump Empty, Pump Stopped When the pump stops, the liquid in the discharge piping flows back through the pump, leaving the priming chamber filled with sufficient liquid for the next priming cycle. Except for the first fill-up of the priming chamber and an occasional “topping off” in dry climates, the Flowserve Durco Unitized Self-Priming is automatic and trouble-free.

gravities lower than 1.0, use 1.0 in the equation. The practical limit of a self-priming pump is 6.1 m (20 ft), divide this amount by specific gravity to determine the actual lift limit. For example: 6.1 m (20 ft) ÷ 1.4 = 4.4 m (14.3 ft) maximum possible lift. Suction Pipe Size The self-priming pump primes by evacuating the air in the suction piping. The priming time curves are based on the volume of air contained in a pipe length equal to the actual static lift shown plus that contained in 1 m (3 ft) of horizontal run into the pump. The pump example lifting liquid 3 m (10 ft) and horizontally 1 m (3 ft) contains 0.0188 m3 (1150 in3) of air in the suction
Specific Gravity As specific gravity increases, priming times also increase. For example: A pump previously lifting 3 m (10 ft) of water (1.0 sp.Gr.) is now pumping a liquid with a specific gravity of 1.4. The 3 m (10 ft) actual lift x 1.4 sp.gr. becomes an effective lift of 4.3 m (14 ft), for a priming time of 26 seconds. To be conservative for specific

Static Suction Lift The higher the lift, the greater the amount of air in the suction pipe to evacuate and the longer the priming time. Example illustrated: A 3x2US-13 pump with a 330 mm (13 in) impeller lifting water 3 m (10 ft) would take 18 seconds (Graph A). A lift of 4.6 m (15 ft) would take 30 seconds.
Suction Pipe Velocity, m/s
Individual pump curves found in Bulletin P-12-102 contain graphs of both hydraulic performance and priming time. Once a pump has been selected based on speed, efficiency, flow and head, priming times may be determined from these graphs. As pump performance varies with RPM and impeller diameter, priming times also change. Factors such as static suction lift distance, specific gravity and suction pipe size also have a direct bearing upon priming times.

pipe (Graph B). Extending the pipe’s horizontal run to 2.7 m (9 ft) gives an additional 0.0090 m3 (530 in3) of air to evacuate before achieving prime. 1680 1150 x 18 sec = 26 seconds, or 8 seconds longer priming time.
When a self-priming pump primes, a significant volume of air is evacuated from the suction line. A selfpriming pump will not work unless there is a way for the air to be vented. Flowserve suggests that a vent line be run from the discharge as shown on the diagram to the above. 46

Flowserve Durco Pre-Engineered Priming Tanks
Selection Criteria 1. Select priming tank with maximum design capacity equal to or greater than the maximum process flow rate from Table 3 on page 51. 2. Determine NPSHa for the pump, including head loss thru priming tank from Table 1. 3. Confirm from Table 3 that suction lift required does not exceed tank capabilities. 4. Select pump to assure NPSH r of pump is less than NPSH a of system. Good Pump Practice recommends the difference be 1.5 m (5 ft) or 20%, whichever is greater.
Design/Installation Criteria 1. Provide suction pipe prior to the priming tank the same size as tank inlet and outlet. Pipe length from the tank to the liquid level should be limited to 6 m (20 ft). This provides the maximum volume of air the tank will prime. A change in pipe dimensions must not result in greater air volume to be primed. NPSH and submergence factors must also be considered. 2. Provide 10 diameters of straight suction pipe to pump inlet where possible. Suction pipe between the priming tank and pump may be reduced (eccentric reducer) to match pump suction size.

3. Install a low level switch in the sump to ensure that the minimum submergence is maintained. The minimum submergence depends on the fluid velocity at the pipe inlet. That fluid velocity varies with the inlet diameter. If the liquid level in the sump allows air into the suction pipe, the tank will lose prime and the pump will empty the tank of liquid. See Submergence Table 2. 4. Provide a check valve on discharge pipe to avoid siphon problems. 5. Seal all pipe connections and the pump to prevent air ingress and loss of prime. 6. Anchor the priming tank to the foundation through holes in pads on bottom of tank legs. See certified dimension prints for size and locations. 7. Provide proper piping support.

Mark 3 Recessed Impeller
Recessed Impeller
Trouble-free pump ing of solid, stringy or fibrous slurries. Delivers efficient operation and low NPSHr. Vortex Pumping Action is your Best Choice for: • Erosive/corrosive slurries • Degradation sensitive crystals • Shear sensitive liquids • Stringy solids • Waste water Impeller Dynamics The vortex created by the spinning impeller does the pumping with less than 20% of the media actually contacting the impeller. Abrasive wear is minimized and solids integrity is maintained. Precision-cast impellers ensure peak energy efficiency and low NPSH requirements. Rear pump-out vanes are used as necessary to ensure low, positive seal chamber pressure and to expel solids from the seal area, thus maximizing mechanical seal and packing life. The impeller is set to the rear cover plate – just like the standard reverse vane impeller.
52
Casing Dynamics The cylindrical volute design combined with the impeller spinning “out of the flow” minimize radial loads on the impeller. The result is longer seal life as well as maximized radial bearing life. The circular flow path and tangential discharge also contribute to maximum pump life.
Applications • Abrasive waste water • Biological sludge • Clarifier underflow • 5% coke slurry • Diatomaceous earth slurry • Floculant sludge • Latex • Lime mud slurry • Organic slurry • Polymer slurry • Resin slurry • Rubber crumb slurry • Sodium hydroxide • Catalyst slurry

Flowserve Durco KW941 Pump Power Monitor™
The KW941 Pump Power Monitor monitors and displays actual power to the pump offering simultaneous protection from underload and overload operating conditions. The KW941 helps to eliminate costly downtime and expensive pump repairs caused by: • Dry running • Pump overloads • Cavitation • Blocked lines • Closed suction or discharge valves • Excessive wear or rubbing By sensing power and not just amperes, linear measurements are given which help to eliminate unwanted nuisance trips. Broad Application Range • Works on all pumps having steady (non-pulsating) loads: centrifugal; gear; turbine; ANSI; API; paper stock; sealed; mag drive; can motor; self-priming Easy Installation • Simple wiring procedure • Easily installed on existing pump installations Easy Setup and Calibration • Settings controlled from front panel push buttons; no internal adjustments, dip switches or potentiometers • Large digital display for easy viewing and accurate settings • One step calibration can be performed without operating pump. No need to run pump at off-operating conditions to calibrate power monitor • Settings can be viewed or adjusted during normal pump operation
56
Premium Features for Reliable Protection • Push buttons display horsepower or kilowatts; automatic conversion when switching displays • Adjustable low power and high power set points protect pump from underload and overload operation. Alarms can be tripped or pumps shut down before damage occurs • Adjustable trip delay timers filter out nuisance trips caused by temporary power fluctuations • Adjustable start up delay timer is particularly useful in unloading applications • Optional 4 to 20 milliamp analog output. Facilitates remote displays, operator interface and output to PLC or DCS • Two form C relay outputs for low and high power trips. Outputs can be used to shut down pump or trip alarms • Automatic, manual and remote reset options for versatile operation
The KW941 Power Monitor is easy to install on new or existing pump installations. All connections and controls are located at motor starter electrical enclosure as shown above. Costly instrumentation wiring to the pump is eliminated.

Flowserve Durco KW941 Pump Power Monitor™
Specifications Display/Control Module
Full Scale Range Adjustable 0.7 to 112 kW (1 to 150 hp). To 447 kW (600 hp) using current transformer (not included). Display 3 digit, 15 mm (0.6 in) high, 7 segment, red LED digital display. Red LED indicators for display mode, trip delays and trip points. Enclosure Polycarbonate, NEMA 4X/IP66 with see-through cover. Four #8 (4 mm) mounting holes. Enclosure can be drilled, sawed or punched on bottom or back for wiring access. Power 110 VAC (220/240 VAC optional), 50/60 Hz @ 0.125 amperes. Power is obtained from a control voltage transformer (not supplied) connected between two phases of the three-phase motor power source. Operating Temperature -44° to 70°C (-40° to 158°F) Adjustable Trip Set Points • High Power: When power exceeds the trip point setting, the trip delay is activated. When the trip delay has timed out, an alarm contact relay will trip.
• Low Power: When power falls below the trip point setting, the trip delay is activated. When the trip delay has timed out, an alarm contact relay will trip.
Adjustable Trip Delay Timers Delay timers eliminate trips during motor starting and false trips due to temporary power fluctuations. Individual timers are adjustable from 0-to-999 seconds: • Start-up Delay • Lower Power Trip Delay • High Power Trip Delay Alarm Relay Contacts Form C relays for low power and high power trip points. • Ratings – 5 amps @ 125 VAC – 3 amps @ 277 VAC – 5 amps @ 30 VDC Analog Output (Optional) 4 to 20 milliamp output proportional to full scale setting. Maximum loop load resistance – 600 ohms. Trip Reset Options • Automatic: Automatic trip reset may be selected on the display/control module. • Manual: Trips may be reset manually on the display/ control module. • Remote: Trips may be reset remotely using a momentary external mechanical or solid state switch.

Typical Low Flow/ No Flow Pump Protection Zone
At low loads, motor amperes do not change much with small changes in pump loads. Small signal changes can cause false trips or allow equipment to operate below the desired minimum operating point. At low loads, power is linear. Small changes in pump operating loads provide greater signal changes. The KW941 is more sensitive to pump load changes and offers easier setup, more reliable equipment protection and no false trips.

Good Pump Practice
Good Pump Practice
Extending MTBPM by Reducing Internal Stress and Vibration in the Process Pump System Package Flowserve is recognized worldwide as the premier name in ANSI pump performance. Its technologically advanced product enhancements have extended MTBPM to new levels. By implementing Good Pump Practice, peak operating performance and economy can be further improved. These seven general principles apply to sealed and sealless pumps.
58
Selection • Sizing with less than maximum synchronous speed rpm where practical • Impeller trim from 95 to 60% of maximum with 75% optimal • Operate from 85% to 110% of BEP • NPSHa 20% or 1.5 m (5 ft) over NPSHr, whichever is greater • Consider variable speed technology for multiple operating point conditions Balance • Impeller balanced to 20 gmmm/kg (0.011 oz in/lb), after trimming. Two-plane spin balance when outside diameter to width ratio < 6 and single plane when ≥ 6 • Coupling balanced to AGMA 8 (AGMA 10 over 56 kW [75 hp]). Coupling to be elastomer type for soft start • Offset pump and motor shaft/coupling hub keyways 180° and cut keys to one-half unfilled keyway length
Installation • Level pump/base/motor – free of soft foot conditions • Provide 10 diameters of straight pipe to suction inlet. Flow conditioning technology may be an option • Rigid baseplate design – reinforced stilt – grout installed baseplate • Grout with low shrink cement; epoxy grout preferred • Special cleaning and primer to bond base with epoxy-type grout • Piping design to assure minimal stress (fasteners installed without force)
Alignment • Use laser or reverse dial indicator technology. Recommended tolerances to: parallel 0.05 mm (0.002 in) FIM; angular 0.0005 mm/mm (0.0005 in/in) FIM • Align before and after pipe-pump bolt-up • Specify bolting to fit without force to connect pump and pipe • Consider C-flange motor adapter for pumping temperatures > 93°C (200°F) or hot align after start-up • Consider C-flange adapters when minimum and maximum pumping temperatures are more than > 56°C (100˚F) apart • For pumping temperatures > 177°C (350°F) consider centerline mounted casing and include C-flange adapter > 260°C (500°F)

Good Pump Practice Preventive Maintenance • Change lubricant at recommended intervals • Protect lubricant from contamination • Use sealed or “vapor block” power end protection and synthetic lubricant to reduce relubrication intervals • Maintain mechanical seal flush environment. Eliminate the need for flush with alternate seal and seal chamber designs when possible • Maintain power end and mechanical seals in a “clean room” • Predictive maintenance, vibration monitoring and lubricant analysis are still good practice
Operation • Develop suitable start-up procedures and checklists • Avoid rapid closing of process valves (no water hammer) • Use a power monitor for minimum/maximum flow protection • Add minimum flow bypass as required • Consider soft start for frequent on-off duty • Consider variable speed technology for inherent soft start, reduced RPM and increased efficiency • Do not run dry. Check for submergence conditions, particularly in batch operation. Select pump/seal type accordingly • Operate spare pump every three (3) months
Design/Specifications • Use solid shafts – Index of Deflection: (I = L3D4) Group 1 < 75 Group 2 3500 rpm < 40 1800 rpm < 65 Group 3 ≤ 25 • Use cartridge seals designed to reduce fretting corrosion and for proper setting 100% of time • Maintain critical impeller setting tolerances to hold low thrust load and seal chamber pressure • Specify state of the art seal chamber designs that offer anti-rotation features to reduce abrasion, vaporization, heat and cavitation at the mechanical seal • Pump manufacturer to be responsible for “Total Engineered Seal System” (TESS) • Rigid, cast iron motor foot construction with ≥ 182T(S) frame sizes
Note: Some items are more critical for longer term installations and become economical when life cycle cost considerations are applied. For further information, contact a Flowserve salesperson.
