American Approval of an American National Standard requires verification by ANSI that the requirements tor due process. consensus and other criteria for approval have been met National by the standards developer. Standard Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered , and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the startJdards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard . Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for inte rpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard . Purchasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

Revis io ns The Standards of the Hydraulic Institute are subject to constant review, and revrsions are undertaken wheneyer it is found necessary because of new developments and progress in the art. If no revisions are made for five years, the standards are reaffirmed using the ANSI canvass procedure. Units of Measurement US Customary units of measurement are predominantly used. Due to the reference to ANSI/ASM E 873 standards for pump dimensions conversion to Metric units was inappropriate. Consensus for this stan dard was achieve d by use of the Canvass Method The following organizations, recognized as having an 1interest in the standardization of centrifugal pumps were contacted prior to the approval of this revision of the standard.

Driver I pump coupling alignment The allowable radial movement of the pump shaft at the pump coupling hub due to nozzle loads shall not exceed 0.005 inch parallel relative to initial alignment. Axial movement of ~he pump shaft at the pump coupling hub is not considered. 9.6.2.1.3.2

Internal pump distortion

No contact between moving and stationary parts is allowed (i.e., casing and impeller) . The allowable radial movement of the pump shaft with respect to the seal chamber due to nozzle loads shall not exceed 0.001 inch relative to initial position. 9.6.2.1.3.3

baseplate. RG!fer to API 686, Appendix E. for required torque values (use %inch nominal bolt diameter torque value for Group 1 and 2 pumps and ~inch nominal bolt diameter value for Group 3 pumps). It may be necessary to arrange for periodic tightening of the bolts to maintain required torque levels. 9.6.2.1.3.4

Pump mounting

The base for which the loads in Tables 9.6.2.1.1 through 9.6.2.1.4 are established must be a fully grouted metal baseplate with anchor bolts. The base as a minimum must withstand the applied nozzle loads combined with normal operating loads (i.e., driver weight and pump weight). · The base must be installed and grouted in accordance with ANSI/HI 1.4-2000, Centrifugal Pumps for Installation, Operation and Maintenance.

Pump hold down bolts 9.6.2.1.3.5

The maximum allowable· tensile stress allowed in the pump hold-down bolts is 90% of ASTM A 307 Grade A fastener material yield strength. The maximum allowable shear stress allowed in the pump hold-down bolts is 25% of ASTM A 307 Grade A fastener material yield strength. Fasteners used for hold-down bolts must have a yield strength greater than or equal to ASTM A 307 Grade A fastener yield strength . The pump shall be bolted to the baseplate at both the casing feet and rear foot position(s) and sufficiently tightened to prevent slippage of the pump on the

Nozzle stress

The maximum stresses developed in the pump nozzles and flanges by the applied nozzle loads combined with internal pressure will not exceed 26,250 psi tensile and 13,125 psi shear. This is in accordance with the allowable stress for ASTM A351 (A 744/743) Grade CF8M per ASME Boiler and Pressure Vessel Code. The suction nozzle stress is calculated using three dimensional stress analysis methods. The discharge nozzle stress is calculated based on the method contained in the ASME Boiler and Pressure Vessel Code, 1983 Edition, Section Ill, NC 3653, due to its complex geometry. 9.6.2.1.3.6

Pressure-temperature

The temperature shown for a corresponding allowable nozzle load is the temperature of the pressurecontaining components of the pump. In general, this temperature is the same as that of the contained liquid. Use of a pressure rating as specified in ANSI/ASME B16.5 corresponding to a temperature other than that of the contained liquid is the responsibility of the user, subject to the requirements of the applicable code or regulation. Low-temperature and high-temperature considerations addressed in ANSIIASME B16.5 should be examined. Figure 9.6.2.1.1 -Coordinate system for ASME 873.1 M horizontal end suction pumps

HI Centrifugal and Vertical Pumps for Allowable Nozzle Loads 9 .6.2.1.4

ANSI/ASME 873.1M pump nozzle loads

Loads given in Tables 9.6.2.1.1 through 9.6.2.1.4 are applicable for ASME 873.1M pumps constructed of ASTM A 7 43/744 - Grade CF8M (Type 316SS) operated between - 20°F and 1oooF and mounted on a grouted metal baseplate with anchor bolts. For an individual force or moment, pumps must be capable of satisfactory operation when subjected to loads shown in Table 9.6.2.1 .1 (adjusted if applicable) while meeting the criteria of Equation Set 1. Each load in Table 9.6.2.1.1 is such that it is the maximum ind ividual load for that particular load without any other loads applied. For a combination of more than one force and/or moment, pumps must be capable of satisfactory operation when subjected to the loads in Tables 9.6.2.1.2 through 9.6.2.1.4 (adjusted if applicable) while meeting the criteria of Equation Sets 2-5. When combining loads, the absolute value of any individual load must not exceed the value given in Table 9.6.2.1.1.

If mounting the pump on a base other than a fully grouted metal baseplate with anchor bolts , refer to Section 9.6.2.1. 7 for allowable load adjustment factor. 9.6.2.1.7

Nozzle load adjustment factors

The loads in the tables must be multiplied by adjustment factors when applicable. The lowest correction factor should be applied when more than one adjustment factor is involved. For instance, if the pump is an ASME B73.5M pump (90% reduction factor) mounted on a fully grouted non-metallic baseplate (80% reduction factor) , then the reduction factor for Tables 9.6.2.1.1 through 9.6.2.1 .4 would 80%. There may be cases where one adjustment factor is applied to Table 9.6.2.1.2 and another adjustment factor is applied to Tables 9.6.2.1.3 and 9.6.2 .1.4. These cases are denoted in the text. Refer to Appendix A for further discussion of nozzle load reduction factors. 9.6.2.1.7.1

Adjustment of allowable load values is required if any of the following occur: a)

Temperature is above 1oooF

b) The pump material construction is not ASTM A 744- Grade CF8M c) The base is not a fully grouted metal baseplate with anchor bolts Refer to Section 9.6.2.1.7 for allowable load adjustment factors. 9.6.2.1.5 ANSI/ASME 873.3M sealless pump nozzle loads Allowable loads and adjustment of allowable loads for pumps built to ASME 873.3M, Specification for Sealless Horizontal End Suction Centrifugal Pumps for Chemical Process is identical to ASME . 873.1 M pumps. Refer to Section 9.6.2.1.4. 9.6.2.1.6 ANSI/ASME B73.5M composite pump nozzle loads By reducing the values in Tables 9.6 .2.1.1 through 9.6.2.1.4 to 90% of their original values, the values are applicable for ASME B73.5M pumps mounted on a grouted metal baseplate with anchor bolts. Use Equation Sets 1-5 with these adjusted values.

2001

Alternate pump mounting

For alternate mounting conditions, the pump must be mounted on a base that can, as a minimum, withstand the applied nozzle loads combined with normal operating loads. 9.6.2.1.7.1.1

Stilt-mounted metal baseplate

Use 100% of the values in Table 9.6.2.1.2 and 90% of the values in Tables 9.6.2.1 .3 and 9.6.2.1.4. If after adjusting the value for a particular load in Tables 9 .6.2.1.3 and 9.6.2.1.4., the absolute value of any adjusted value is lower than the corresponding load in Table 9.6.2.1.1 , substitute the lower value into Table 9.6.2.1.1. All of the values in Tables 9.6.2.1.1 through 9.6.2.1.4 may be used if it can be demonstrated that the baseplate design meets the deflection criteria contained in ANSI/HI 1.3-2000, Centrifugal Pumps for Design and Application. Warning: Forces and moments must be limited to values lower than that which will initiate overturning or lifting of the pump, base, and driver assembly. 9.6.2.1.7.1.2 Ungrouted metal baseplate that is anchored down Use 100% of the values in Table 9.6.2.1.2 and the values in Tables 9.6.2.1.3 and 9.6.2.1.4. adjusting the value for a particular load in 9.6.2.1 .3 or 9.6.2.1.4, the absolute value

Adjustment factors are determined by taking the ANSI/ ASME 816.5 Class 300 pressure-temperature rating of the flange material being used and dividing by the pressure-temperature rating of ASTM A 351 - Grade CF8M Class 300 at 100°F as specified in ANSI/ASM E 816.5. In the case of ductile cast iron, adjustment factors were determined by taking the ANSIIASME 816.42 Class 300 pressure-temperature ratings and dividing by the pressure-temperature rating of ASTM A 351 Grade CF8M Class 300 at 100°F as specified in ANSI/ ASME 816.5. 9.6.2.1.7.2.2

Use 70% of the values in Tables 9.6.2.1.1 through 9.6.2.1.4. All of the values in Tables 9.6.2.1.1 through 9.6.2.1.4 may be used if it can be demonstrated that the baseplate design meets the deflection criteria contained in ANSI/H I 1.3-2000, Centrifugal Pumps for Design and Application. 9.6.2.1.7.1.5

For temperatures above 1oooF and/or the use of a material other than ASTM A 744 - Grade CF8M, the loads in Table 9.6.2.1.2 should be reduced by multiplying them by the proper adjustment factor from Table 9.6.2.1.6. For intermediate temperatures not shown in Table 9.6 .2.1.6, linear interpolation is permitted. If after adjusting the value for a particular load in Table 9.6.2.1.2, any adjusted value is lower than the corresponding load in Table 9.6 .2.1. 1, substitute the lower value into Table 9.6.2.1 .1 .

NOTES: Please note that certain sizes do not follow a ·trend of increased allowable nozzle loads with increased pump size. This is due to interaction of individual pump geometry (i.e., nozzle wall thickness, distance from flange face to nozzle connection with casing, etc.).

a This is not an ASME size. It is included here as a special Group 1 size that is common among manufacturers.

The allowable individual nozzle loads for Table 9.6.2.1.1 are based on the following formula:

I< 1 0 Mys I< 1 0 I Mzs I< 1 0 F xs I< 1 0 I F ys I
