Product Information Introduction Brandt® MA-RG Series Agitators are heavy-duty mechanical mixers for viscous fluids. The gearbox is a helical-bevel gear drive system that reduces the rotational speed of the motor to drive the impeller(s). The impeller shaft is suspended from and attached to the output shaft of the gearbox. Several models are available to meet a variety of mixing needs. The naming convention for these models is: MA-XRG where X = the horsepower of the unit and RG indicates the helical-bevel gearbox. For example, MA-20RG is the 20 hp mud agitator with a helical-bevel gearbox. MA-RG Series Agitators are very compact. Their low profile reduces headroom requirements and provides more layout space on top of the tanks. The 1:1 height-to-width ratio results in a lower center of gravity, providing stability and safety should the impeller encounter a sudden shock load. MA-RG Series Agitators use a mounting skid. An even lower profile version of the MA-RG Series Agitator is offered in which a base plate is used instead of the mounting skid to reduce the overall height. The naming convention for the agitator with a base plate is: MA-XRGLP Another variation of the MA-RG Series Agitators has a C-face motor with a close coupling style. This variation also has a base plate instead of a mounting skid and naming convention is: MA-XRGC For example, the MA-3RGC is the 3 hp mud agitator with a helical-bevel gearbox, a base plate and a C-face motor. Each MA-RG Agitator uses a shaft-mounted impeller to maintain a homogeneous mixture of liquids and solids within a tank. Impellers are available with flat blades (radial flow), contour blades (axial flow), and canted blades (radial/axial flow). Blades may be installed in single or multiple configurations to provide the desired results. There are several options available for MA-RG Series Agitators. Popular options include special paint finishes, remote starters, other electrical controls, and special duty motors. Contact your sales representative to discuss which options may be right for your application. See Chapter 8, titled "Worldwide Locations" to locate the office nearest you.

2: Product Information

Unit Description Each MA-RG Agitator consists of a motor, gearbox, mounting base and shaft-mounted impeller. Electrical controls, special coatings, custom bases, and other options are available.

Motor The motors used on the mud agitators are explosion proof, three-phase electric motors directly coupled to the gearbox using a flexible coupling with a solid steel guard. Motors are available for most voltage/frequency requirements. Other electrical code styles and temperature ratings are also available.

Nominal motor ratings Volts

Gearbox The gearbox is a triple-reduction helical-bevel gear drive reducing the motor speed (1800 rpm @ 60 Hz / 1500 rpm @ 50 Hz) to the agitator speed (60 rpm / 50 rpm respectively) in a 30:1 nominal reduction. The actual output speed varies by motor and gearbox size. The gearbox contains an output shaft, two seals, and four to six bearings in addition to the helicalbevel gear system. The bearings are generously spaced to minimize shaft vibration and deflection. Seals are standard sizes readily obtainable.

Mounting Base The motor and gearbox are assembled on a common base with heavy grade fasteners. The base is sand blasted to white metal, primed with zinc and finish coated with epoxy. Special coatings are available as an option.

Impeller Impellers may have flat blades (radial flow), contour blades (axial flow), or canted blades (both radial and axial flow). Blades may be installed in either single or multiple configurations to provide the desired results. Impellers range from 32 in. to 64 in. (813 to 1626 mm) in diameter for canted and flat blades and 20 in. to 64 in. (508 to 1626 mm) in diameter for contour blades. Flat-blade impellers are recommended for tanks less than 5 feet (1.5 m) in depth. Use canted or contour blades in tanks deeper than 5 feet (1.5 m). You may also mount a combination of types on a single shaft in tanks deeper than 15 feet (4.5 m). Larger custom-designed blades and mixing systems are also available. See Chapter 8, titled "Worldwide Locations" to locate the office nearest you.

Flat-blade Impellers When properly mounted, these impellers produce adequate agitation in shallow tanks, but may require baffles to induce both axial and radial flow. Flat blades do the best job of preventing solids from settling on the tank bottom. (See Figure 2-1.)

Figure 2-1. Flat blade impellers promote radial flow in shallow tanks.

Canted-blade Impellers On canted blade impellers (see Figure 2-2), the blades are angled downward at 60° to promote axial as well as radial flow. Canted blades shear and circulate to provide quick mixing. Vortexing may occur with canted blades.

Figure 2-2. Canted blade impellers promote axial flow within a tank.

Document number Revision Page

M14030 11 9 of 114

Contour-blade Impellers On contour blade impellers (see Figure 2-3), the blades are designed with a variable pitch reducing the horsepower requirements and inducing less shear to the mud. Contour blades move liquid downward to the bottom of the tank, along the tank bottom toward the tank walls and then up the tank wall. All fluid in the tank is mixed continuously and the same consistency is maintained in all parts of the tank. Field experience has confirmed that this design provides the most homogeneous mixture in the widest range of installations. Complete fluid agitation minimizes fluid control problems caused by inconsistent mixtures. Contour blades also use less horsepower than canted blades.

Figure 2-3. Contour blade impellers promote axial flow with less shear to the mud.

Multiple Impellers When an agitator is used in an extremely deep tank, over 15 feet (4.5 m) deep, multiple impellers can be mounted on one shaft. Usually the upper impeller(s) is a canted or contour blade and the bottom impeller is a flat blade. A bottom shaft stabilizer is often required for multiple impellers. Contact our engineering department for proper impeller sizing and stabilizer requirements. See Chapter 8, titled "Worldwide Locations" to locate the office nearest you.

Impeller Placement Flat-blade impellers should be placed 6 in. (152 mm) above the bottom of the tank or 2 in. (51 mm) above the bottom shaft stabilizer if one is used. Canted and contour blade impellers should be placed on the shaft so that the distance between the bottom of the tank and the lower edge of the blades is equal to 0.75 times the diameter of the impeller. For example, a 36 in. (914 mm) impeller should be placed 27 in. (686 mm) above the bottom of the tank.

Handling Planning Meeting For handling the agitator and shaft crates to the site, personnel involved should attend the Planning Meeting to decide on the safest, most direct route to move the agitator and shaft crates into position as close as possible to the final location.

Risk Assessment Risk assess any potential hazard that may lead to serious injury or death when transporting the agitator and shaft crates. Hazards must then be addressed by all key personnel to ensure safe transit of the crates to the site location.

To Site Extreme care must be taken to prevent damage when moving the agitator and shaft crates. Ideally, the use of a spreader bar with soft fabric slings is the recommended support method for lifting. Never lift a crate with only one support point. Only certified sling sets are to be used. Ideally, soft fabric slings should be used to minimise damage to the crates or components. All lifting equipment and procedures must comply with applicable safety requlations. 

Unpack



Component check



Inform NOV of damage

Unpack Personnel should always unpack the agitator and shaft in an efficient and safe manner providing a clean and safe working environment. The equipment will be delivered to the site in crates. Remove any protective sheeting and steel banding used to secure the crates. Remove the lid and then the sides, taking particular care not to damage the equipment or cause injury to any personnel. Any small loose items should remain in the crates awaiting storage or installation.

Component Check All components enclosed in the agitator and shaft crates are to be thoroughly checked against the packing list to ensure all items have been delivered/received.

Installation - Planning Meeting Planning meeting is to be carried out prior to installation of the agitators and shafts. A clear plan of action is to be deduced involving key personnel on how best to install the agitators and shafts efficiently and safely.

Installation - Risk Assessment All potential hazards that may lead to serious injury or death during the installation process must be taken into account. Hazards must then be addressed by all key personnel to ensure a safe and efficient installation of the agitators and shafts.

Handle to Final Location The installation activities involve substantial lifting and handling operations with some heavy and awkward components weighing up to 2500 lb (1133 kg) individual weight. Loads may also require to be handled through floor, bulkhead hatches and doors. To assist with this handling, it is recommended to ship the larger, heavier components partially disassembled for easier and safer installation. Actual handling procedures and sequence of activities may be changed as dictated by rig activities and experience gained with the handling of installation components.

Support Structure Adequate support must be made in the deck in order to support the agitator correctly. Suitable structure should be designed based on reaction forces specified on the installation drawings (if applicable included in documentation package) and/or in this manual. The following information should be reviewed and taken into consideration: 

Agitator weight and design loads (Refer to table titled "MA-RG Series Models" on page 11 for weights of agitators and table titled "Impeller Shaft Measurements" on page 10 for shaft weights and maximum torque.)



Location and size of skid mounting holes (Refer to Chapter 7, titled "Parts and Drawings".)



Placement of structural members to allow full contact support for the agitator skid footprint Use of structural members of equal or higher rigidity to the material used in the agitator skid is recommended. Typically I-beams of respective strength in the lateral and horizontal bulk head to bulk head cross sections is sufficient to support the base/skid of the agitator.



Placement of the agitator Directly to the tank deck is recommended. Lowering the mounting height improves the strength of the structure and lowers the center of gravity, improving resistance to vibration.



Tank openings required to place the shaft and impeller into the tank



Proper placement of the impeller



Proper size and location of the baffles

The agitator frame should be supported by a rigid structure making the first fundamental natural frequency of the whole system 15 % above the operating rotating frequency of the motor and having following characteristics: 

flat and level



structural members to support the perimeter of the agitator skid with full-face contact

Document number Revision Page

M14030 11 16 of 114

3: Installation

The agitator skid has been engineered to have the first natural frequency 50 % or more above the motor operating speed. The natural frequency of the combined rigid structures is different than that of its components as well as dependent on the rigidity of their connection. Verification of the natural frequency of an as-installed structure might be helpful in eliminating any resonance. Should resonance of the combined structure occur, it can be eliminated by modification of either the supporting structure or the rigidity of agitator skid to support structure connection. The system natural frequency is typically directly proportionate to its stiffness. Increasing stiffness will shift the natural frequency up, thus decreasing the possibility of resonance. This can be achieved by: 1. use of rigid, symmetrical and leveled structural support for the agitator base. 2. adding cross members to the support structure. 3. minimizing the gaps between the agitator base and the support structure or closing of the gaps by welding. Minimize the use of shims. 4. minimizing agitator shaft misalignment.

Below is an example of an installation where adequate primary structural support was added to strengthen the deck area in which the agitators were installed.

After Figure 3-1. Support structure

Please note that sub support frames for the agitator baseplates must be suitably fabricated. Inadequately fabricated support frames can cause instability or vibration issues.

Below is an example of a sub frame with inadequate support.

Figure 3-2. Inadequate support

Lifting and Mounting Lifting should be performed with proper lifting equipment and using only the designated agitator lifting points. The agitator should be stored and lifted with its shipping crate until it is ready to be installed in its final destination. The agitator should never be rested on the gearbox output shaft. Once the agitator is in its intended position, check the alignment of the mounting holes and gaps between the agitator skid and support structure as follows: 

The gap between the agitator skid and support structure at the bolting points before bolt down should be less than 0.025 in. (0.635 mm). Gaps at the bolting points ranging from 0.025 in. (0.635 mm) to 0.5 in. (12.7 mm) should be eliminated using shims to prevent deflection of the agitator skid and impact on shaft alignment.



Minimum allowable shim size is 2 in. (51 mm) x 2 in. (51 mm) by the shim thickness.



Maximum allowable shim thickness is 0.5 in. (12.7 mm). Thicker shims must be welded to the foundation.



No gap is allowed between the bolted components after tightening the bolt as it can cause "soft foot" phenomenon.



If needed, the agitator skid can be permanently welded to the supporting structure to close excessive gaps between the structures. Alternatively, the support frame can be build and fitted to the agitator skid before being welded to the tank deck. Any gaps resulting from unevenness of the tank structure can be closed while welding the support frame. Ensure that the skid is grounded before welding. Failure to do so can result in electrical system damage.

Installation All MA-RG Agitators are supplied as shop assembled agitators. All shaft assemblies are broken down into various separate parts (shaft complete with coupling/bushing assembly, impeller assembly and stabilizer housing) to aid in maneuvering parts into mud pits with restricted access. Two type of shafts are manufactured; either a solid shaft that is keyed for the impeller or a pipe spool to which the impeller is bolted. The solid shaft installation instructions are given followed by the pipe spool installation instruction on page 31.

3: Installation

Mechanical Installation 1. Refer to the "Taper-Lock Coupling Installation Instructions" that is supplied in the "Supporting Documents". These should be reviewed to familiarise the user with the shaft fixing components being used. 2. Before locating the agitator on top of the tank, ensure the surface is square and level. 3. Ensure before installation of the agitator onto the top of the tank, the structure is strong enough to hold the unit and the tank dimensions are correct as per the general arrangement drawings. It is recommended the agitators are bolted to rigid beams. 4. The agitator assembly can be lifted to its location and into place using the four lifting eyes provided on the unit and a correct four leg lifting sling assembly (not supplied). The agitator assembly should be placed on blocks in the exact location it will be secured to give 19.685 in. (500 mm) clearance from the bottom of the tank to the bottom of the shaft assembly when the shaft assembly is fitted to the agitator assembly. This is to ensure the stabilizer will be fitted in the correct location. The agitator assembly and shaft assembly need to be fitted before the stabilizer to ensure correct alignment.

Figure 3-7. Agitator lifting

5. Ensure access into the tanks is large enough for the shaft assemblies, impeller assemblies and stabilizers. If it is possible to assemble the shafts completely before positioning inside the tank, skip to step 8. 6. The impeller assemblies can be reduced in diameter by removing the blades, up to 4 if necessary. 42 www.nov.com/brandt

9. For a single shaft and single impeller, do not remove the coupling already fastened to one end. The preservation fluid needs to be removed from the shaft at this stage.

Figure 3-9. Single shaft with one half coupling

10. Install the impeller the correct way up. The impeller blades should be oriented so that the fluid is pushed downward when the agitator is rotating clockwise when viewed from the top, i.e. the leading edge of the paddle will be in the higher position with the trailing edge in the lower position. 11. Ensure the bushing key is in the shaft keyway. Slide the impeller onto the shaft past the key. Slide on bushing over the keyway and locate with the impeller coupling. 12. Locate the key and slide the impeller so that when the impeller is installed, the distance from the bottom of the impeller blades to the tank bottom is roughly 0.75 times the impeller diameter. For example, if the impeller diameter is 36 in. (914.4 mm), then the distance from the bottom of the impeller blade to the tank bottom should be 27 in. (685.8 mm). If installing dual shafts, the top shaft impeller distance should be taken from the bottom of the top shaft coupling connection to the bottom of the impeller blade.

13. After sliding the impeller into position, secure the impeller. Install the head of the bolts on the underside of the impeller. See the table titled "Fastener Torque (lb-in.)" on page 51 for proper bolt torque values. 14. For assembly of dual shafts, if the top shaft assemblies have been sent to the site with the coupling assemblies on both ends, one end will need to be removed to install the impeller. To remove the coupling, follow step 15 - 19. See Figure 3-8 for top shaft complete with couplings at both ends. 15. The preservation fluid needs to be removed from the shaft at this stage. 16. The bushing, coupling and shaft are secured together. This connection needs to be broken by first removing the screws from the coupling/bushing, then inserting two of these screws into the two jacking bolt holes on the coupling/bushing. Figure 3-11 shows three screws securing the coupling/bushing assembly. The two jacking bolt holes show no screws.

17. When removing the coupling from the bushing using the two screws, it is essential to tighten in the screws evenly. Do not just tighten one screw until it cannot be turned further. This will damage the bushing and coupling threads. Tighten each a little at a time. 18. Once the connection is broken, the coupling and bushing should slide off the shaft easily. They might need a slight tap with a rubber mallet to get the bushing moving, but this is all that it should need. Do not force the coupling and bushing apart. 19. Once the coupling assemblies are apart, complete step 10 - 13 to install the impeller. 20. If the top shaft assembly has been sent to the site with one fixed coupling (similar to Figure 3-9) and the other half of coupling attached to bottom shaft assembly, follow step 10 - 13 to install the impeller blade, then proceed to step 21 to assemble the bushing/coupling assembly. The preservation fluid needs to be removed from the shaft at this stage. The one fixed coupling should not be removed by the user.

21. Once the impeller has been installed, then the coupling/bushing assembly needs to be replaced onto the shaft in the correct fashion. 22. Ensure the shaft end and coupling/bushing assembly are clean and free from any debris, rust, grease or oil and the key is inserted into the keyway. See Figure 3-12 and Figure 3-13.

23. Slide on the coupling half and then slide on the bushing, ensuring the three tightening holes and the two jacking bolt holes line up as in Figure 3-11 and the bushing and coupling are aligned with the end of the shaft. 24. Ensure the screws are tightened up in an even fashion, going in a clockwise direction, as per Figure 3-14 and Figure 3-15. Do not just tighten one screw until it cannot be turned further. This will result in damage to the bushing and coupling threads. Tighten each a little at a time.

25. Once the coupling and bushing are tightened together, the bolts need to be correctly torqued. See the table titled "Fastener Torque (lb-in.)" on page 51 for proper bolt torque values. Not tightening the bolts to the specified torque may result in the shaft falling off the rigid coupling/bushing. Ensure the screws are torqued in an even fashion, going in a clockwise direction as per Figure 3-16 until torqued to the correct setting.

Figure 3-16. Torque clockwise

26. If the shaft has been assembled outside of the tank then, using the appropriate slinging arrangement, lower the shaft through deck cut out on top of the tank. If required, the shaft can be temporarily tied on the side of the tank. When the agitator is fitted with dual shafts, the lower shaft should be put in the tank first.

27. If the shafts are to be stored after assembly on site, preservation fluid must be applied to shafts and couplings. 28. The shaft should now be assembled to the rigid coupling under the agitator gearbox as per Figure 3-17. This half coupling is fixed at the factory and under no circumstances should be removed by the user without consulting with a field service representative. 29. The stabilizer housing should never be permanently installed to the tank floor until the agitator and the shaft are installed, properly aligned and bolted down. Failure to follow this step may result in the shaft falling out of the rigid coupling/bushing. 30. Before installing the stabilizer, make sure the tank floor is suitable to weld the stabilizer. If not, weld a doubler plate on the tank floor directly underneath the shaft. 31. To install, slide the stabilizer over the bottom of the agitator shaft once the impeller has been installed but before the agitator is bolted down. 32. The blocks should be removed and the agitator should be secured to the mud tank using the mount hole pattern shown on the installation drawing, or the unit can be directly welded to the mud tank (provided necessary risk assessments are agreed and approved). www.nov.com/brandt

See the section titled "Bolt Torque Requirements" on page 102 for the correct torque of the agitator fasteners. The shaft alignment should then be checked by rotating the impeller through several revolutions manually.

Figure 3-17. Agitator shaft coupling connection

33. Once the agitator shaft is properly aligned, the stabilizer should be positioned so that the shaft is centered within the stabilizer. 34. In the case of sloping tank bottoms, cut the stabilizer to suit the tank profile. 35. Profiling the stabilizer to suit might result in losing the drain holes on the stabilizer bottom. If so, similar drain holes must be made on to the stabilizer before welding onto the tank. See Figure 3-18.

39. Weld the stabilizer in place. Some contact between shaft and stabilizer is normal during operation, but immediately correct any hard striking. Ensure that skid is grounded before welding. Failure to do so can result in electrical system damage.

Incorrect stabilizer location

Correct stabilizer location

Figure 3-20. Stabilizer installation

If correct position of the stabilizer location cannot be achieved: a. Check the agitator shaft runout. Make sure all connections are flush with no gaps between the two surfaces. b. Check for level mounting of the skid base. c.

From the top, check the hubs/shafts for excessive runout. Proper runout can be verified using a dial indicator at various sections along the shafts and hub connections. High runout might require replacement of the shaft section or sections.

d. It may be required to reinstall the shaft ensuring that all connecting surfaces are clean, making good contact and properly torqued. If water will be used in the tank during start up, the shaft stabilizer should be lubricated with grease to reduce friction and minimize vibration during start up. Operation with mud does not require lubrication. 40. Only after these steps are completed and assured that the shaft is centered within the stabilizer should the stabilizer be permanently secured to the tank floor by means of welding. 41. The shaft should locate into the stabilizer at 50 % of the total height. 75 % is the maximum and 40 % is the minimum. 42. Check the impeller height and adjust if necessary. Reference step 12 for the correct height.

Pipe Spool Installation 1. Before locating the agitator on top of the tank, ensure the mounting surface is square and level. 2. Ensure the support structure is adequately designed to hold the unit and the tank dimensions are correct as per the general arrangement drawings. It is recommended for the agitators to be bolted or welded to rigid beams. 3. Ensure access into the tanks is large enough for the shaft assemblies, impeller assemblies and stabilizers. 4. Place the skid on the foundation and ensure level of the unit. Level check should be performed on skid main beams as well as on the gearbox housing in both directions. Proper shimming is required. See the section titled "Lifting and Mounting" on page 17. 5. After shimming, bolt or weld the unit to the foundation. Ensure that skid is grounded before welding. Failure to do so can result in electrical system damage. 6. Clean all debris, grease and other contaminants from the coupling faces. 7. Bolt the first pipe spool to the gearbox coupling. Torque the bolts to 40 % of the recommended torque. Torque the bolts in a series of diagonally opposite pairs. Tighten each a little at a time up to 40 % of the recommended torque. 8. Check the runout along the pipe spool to observe the trend. See Figure 3-22. Rotate the shaft by hand. Mark the high and low runout points on the bottom of the pipe by the coupling weld. Note runout values. See Figure 3-23. 9. Check the runout on the bottom face. See Figure 3-23. Mark the high and low values. 10. Unbolt the first pipe spool.

Gearbox and Motor Shaft Alignment The agitators are aligned at the factory before performance of the Factory Acceptance Test. The alignment between the shafts should be inspected after installation of the agitator to ensure that transportation, handling or installation has not caused a misalignment. Poor alignment can result in increased vibration and failure or decreased service life of the coupling, gearbox or motor bearings. Alignment should not be attempted until the base is in position and the mounting and flange bolts have been tightened.

The recommended alignment procedure is to use laser alignment tools or dial indicators. The less accurate method of measurement using a straight edge can be used in areas where these alignment tools are not available. The recommended maximum shaft misalignment is specified in table below.

Alignment method

Alignment criteria

Laser alignment

5 mil parallel offset and 1 mil angular misalignment

Indicator alignment

0.010 inches offset and 0.005 inches angular

Straight edge alignment

See the table titled "Maximum misalignment using a straight edge" on page 39

The dial indicator procedure uses the dial indicator attached to one coupling half with the indicator button resting on the O.D. of the other coupling half to measure offset misalignment. To measure angular misalignment, the indicator is positioned so that the button rests on the face, near the O.D., of the other coupling half. Rotate the shaft and dial indicator one full revolution while the other shaft remains stationary and note the Total Indicator Reading (T.I.R). Unless otherwise specified by the coupling manufacturer, offset misalignment should be limited to 0.010 inches T.I.R. and angular misalignment should be limited to 0.005 inches T.I.R. Adjust misalignment by loosening the motor mounting bolts and re-tightening or shimming as required.

In areas where a dial indicator arrangement is not available, an adequate job of alignment can be done with a straight edge. This method is especially useful if the coupling used contains an all rubber drive element. To check offset misalignment, lay the straight edge in line with the shafts on the O.D.'s of the coupling halves. There should be no gaps under the straight edge. Check 4 locations 90º apart. There should be no more than specified gap under the straight edge. See the table titled "Maximum misalignment using a straight edge" on page 39 and Figure 3-32 below.

The unit should be mounted not less than 2 feet (0.6 m) above the servicing level. A height of 5.5 feet (1.7 m) is recommended. Use properly certified seal glands.

Emergency Stop Station This unit is supplied by others and is out of the scope of supply. The unit should be certified Zone 1 and have an ingress rating of IP56 minimum. The unit must be positioned for easy access and for non-hazardous operation by the operator or others who may need to use it. Measures against inadvertent operation should not impair accessibility. The unit should be mounted not less than 2 feet (0.6 m) above the servicing level. Ideal height is 5.5 feet (1.7 m). The ideal position is such that you can see the whole agitator but do not need to go into the danger area to operate it. Other accessible locations can be considered, i.e. close to doorways, exits, etc. The emergency stop should not be used as a functional stop for the unit but should be tested on a regular basis to ensure reliable switching. Weekly testing is recommended. Use properly certified seal glands.

General Electrical Cabling / Distribution Ensure each electric motor has a same voltage and frequency with the accepted tolerance limits voltage +/- 5 %, frequency +/- 2 % of the rig supply voltage. Cables will be run in accordance with the single line block diagram. Great care must be taken when wiring to the electric motors. Only use recommended cable (as per the drawings) or its equivalent. Cables to the electric motors must be externally supported. Cable trays should be installed in conjunction with the appropriate vessel installation / assembly drawings. Ensure the cable is free to move (without excessive movement) prior to the terminal box cable entry. Ensure the cable has sufficient length so as not to be strained during operation preferably by means of a loop or "pig-tail". Do not leave the electrical wires inside the terminal box too long. Always use ring type crimps when attaching the electrical wires to the motor terminals. Use properly certified seal glands. Unused cable entries must be plugged with appropriate certified plugs. 42 www.nov.com/brandt

Grease the motor every three months or as the motor manufacturer recommends.

Gearbox Oil The gearbox can be filled with either a conventional mineral oil or a synthetic PAO (Poly Alpha Olefin) oil depending on the anticipated service temperature range as listed in the table below. The initial oil fill should be changed at 10,000 hour intervals for the conventional mineral oil. In practice, change every 12 months depending on operating conditions. If synthetic oil is used, the interval can be doubled to 20,000 operating hours or every two years. The companies and oil shown below are typical. Mineral-based gear oils must comply with the minimum requirements as specified in DIN 51 517 Part 3. The gearboxes are shipped with ISO VG 220 oil, as shown by the oil type label on the gearbox. When changing the oil, always use the oil grade previously in use. Mixing oils of different grades is not permissible. In particular, synthetic oil may not be mixed with mineral oils or different synthetic oils. If the oil type is changed, the gearbox must be flushed thoroughly with the new oil grade.

Changing the Gearbox Oil Verify the location of the oil drain plug, the breather plug and the oil level plug for your MA-RG Series Agitator model in Figure 6-1. 1. Turn the unit off. 2. LOCKOUT/TAGOUT the power supply to the agitator. Allow the gearbox to cool or open the vent plug before opening the level plug. Hot oil may escape rapidly and cause burns. 3. Remove the oil drain plug. 4. Drain the used oil into a suitable container and replace the oil drain plug. 5. Remove the fill/level plug. 6. Fill the gearbox with the correct amount of acceptable oil. The gear reducer is properly filled when oil just begins to flow out of the oil level hole. 7. Replace the fill/level plug. Gear oil is extremely slippery and sticky. Gear reducers are most easily filled using a pump or pressurized lubrication gun. Be sure to dispose of used oil properly and clean area of any spilled oil after completing this procedure.

8. Restore power to the agitator.

6: Maintenance & Repair

Routine Maintenance Checklist The MA-RG Series Agitator is designed for years of dependable service with routine inspection and maintenance. Additional copies of this checklist should be placed close to the unit for quick reference.

Startup 1. Check the oil level with the agitator turned off. The oil should be within 1/2 in. (12 mm) of the bottom of the oil level hole. Do not overfill.

2. The impeller should rotate clockwise when viewed from top. 3. The oil fill/breather plug must be clear of any obstruction to prevent pressure build-up and possible seal damage. 4. The agitator should operate with no vibration. 5. Check the rubber insert on the input shaft coupling for wear and cracks. 6. For optimal performance, change the oil after the first five days of operation, particularly if the unit has been in storage.

Daily 1. Check for oil leaks. 2. Keep the motor clean and ventilation openings clear of mud build-up or other debris. 3. Check the impeller shaft coupling for proper make-up.

Periodic 1. Check the oil level. 2. Lubricate the gearbox input bearing with the approved bearing grease every 5,000 operating hours. (See the table titled "Formerly Recommended Greases" on page 48.) Do not over lubricate.

3. Change the oil every 10,000 operating hours. (See the table titled "Recommended Oils" on page 49.) 4. Lubricate the motor every three months or as the motor manufacturer recommends. Do not over grease.

INSTALLATION INSTRUCTIONS FOR DODGE® TAPER-LOCK® Rigid Couplings

Figure 2 TO INSTALL BUSHING:

Figure 1 INSTALLATION ON SHAFT:

1.

1.

Read “To Install Bushing,” steps 1 thru 3. Mount the female flange on the shaft end having the least length available. This leaves the longest shaft end for the male flange which requires more room to tighten the bushing. 2. Locate large end of bushing in female flange flush with end of shaft. Tighten bushing per steps 4 thru 6 under “To Install Bushing.” 3. Mount male flange on the other shaft. Locate the small end of the bushing flush with the end of the shaft. Tighten bushing per steps 4 thru 6 under “To Install Bushing.” 4. Locate and align shafts to bring coupling halves together. Pilot diameters and flange surfaces should mate fully against each other before bolting the flanges together. 5. A gap between the mating surfaces anywhere around the flanges indicates angular misalignment. Difficulty in mating the pilot diameter indicates parallel misalignment. Shafts should be aligned with a dial indicator to eliminate misalignment. 6. Insert and tighten screws “A” to the recommended torque given in Table 1. The screws are supplied with the male flange assembly. It is necessary that the shafts be free to move endwise when tightening screws. Using the screw to pull the flange together or into alignment without end float may pre-load the system and cause bearing problems or damage to the coupling.

Clean shaft, bore and outside of bushing, and hub bore of all oil, paint and dirt. File away any burrs. Insert bushing in hub. Match the hole pattern, not threaded holes (each hole will be threaded on one side only). ”LIGHTLY” oil setscrews and thread into those

half-threaded holes indicated by ⊚ on above diagram. 4. Alternately torque setscrews to recommended torque setting in Table 2. 5. To increase gripping force hammer face of bushing using drift or sleeve. (Do Not Hit Bushing Directly With Hammer) Re-torque Screws After Hammering. 6. Recheck screw torque after initial run-in, and periodically thereafter Repeat steps 4 & 5 if loose. DO NOT USE WORN HEX KEY WRENCHES. Table 2 Coupling No.
