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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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.

9.6.2. 1.3 Criteria for loading allowances 9.6.2.1.3.1 . 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 <1 0 I F zs I< 1 0 IF xs max - . ' F ys max - . ' F zs max - . ' IMxs max - . ' IMysmax - . , Mzsmax - . ' F xd I< 1 0 I F yd I< 1 0 I F zd I< 1 0 Mxd I

Scope
This section covers minimum allowable nozzle loads for pumps designed and constructed in accordance with ANSI/ASME B73.2M , Specification for Vertical InLine Centrifugal Pumps for Chemical Process, with Class 150 and 300 flanges. To be applicable, the pump casing and seal chamber or stuffing box must be constructed of a material listed in Table 9.6.2.2.2 and subjected to temperatures between -20°F and 500°F unless otherwise specified. 9.6.2.2.2 9.6.2.2.2.1
Nomenclature and definitions
9.6.2.2.3.1
Criteria for loading allowances Flange stress
The maximum stress developed in the pump flanges by the applied nozzle loads combined with internal pressure will not exceed 26,250 psi tensile and 13,125 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 flange stress is calculated using the method contained in the ASME Boiler and Pressure Vessel Code, 1995 Edition , Section Ill, Division 1, Appendix XI Rules for Bolted Flange Connections for Class 2 and 3 Components and Class MC Vessels.

applied moment about z-axis on suction or . discharge nozzle
applied moment about x-axis on suction or discharge nozzle
The maximum bending (Mx, Mz) and torsional (My) moments are those moments that, when applied to the flange, will develop the maximum allowed flange stress. The maximum shear force (Fx, Fz) equals the maximum bending moment divided by overall pump length: SO, as defined by ASME B73.2M. The maximum axial force (Fy) is that force which will develop tensile stress of 7,000 psi in the flange bolts. This tensile stress is in addition to the stress developed by internal pressure and flange gasket seating loads. The total combined stress must be evaluated for the service conditions and bolts of adequate strength must be used. The minimum required bolt strength is equal to the sum of: (7000 psi) plus (bolt stress due to internal pressure) plus (bolt stress due to gasket loads). Higher nozzle loads may be permitted if bolting of higher than minimum required strength is used. 9.6.2.2.3.2
Pressu·re-temperature
The temperature shown for a corresponding allowable nozzle load is the temperature of the pressure-containing components of the pump. In general, this temperature is the same as that of the contained liquid . .
Figure 9.6.2.2.1 -Coordinate system for ASME 873.2M vertical in-line pumps 10
Use of a pressure rating as specified in ANSI/ASME B 16.5 corresponding to a temperature other than that of the contained liquid is the responsibility of the user,
HI Centrifugal and Vertical Pumps for Allowable Nozzle Loads - 2001 subject to the requirements of the applicable code or regulation . Low-temperature and high-temperature considerations addressed in ANSI/ASME 816.5 should be examined. 9.6.2.2.4
ANSI/ASME B73.2M pump nozzle loads
Loads given in Table 9.6.2 .2.1 are applicable for ASME B73.2M pumps constructed of ASTM A 743/ 744 - Grade CF8M (Type 316SS) operated between 20°F and 1 00°F. For an individual force or moment or for a combination of more than one force and/or moment, pumps must be capable of satisfactory operation when subjected to loads shown in Table 9.6.2.2.1 (adjusted if applicable) while meeting the criteria of Equation Set 1. Each load in Table 9.6.2.2 .1 is such that it is the maximum value for that particular load regardless of whether or not any other external loads are applied. When applying loads, the absolute value of any individual load must not exceed the value given in Table 9.6.2.2.1. 9.6.2.2.5 factors
9.6.2.2.5.1
Adjustment factor basis
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 1 00°F as specified in ANSI/ASME 81 6.5. In the case of ductile cast iron, adjustment factors were determined by taking the ANSI/ASME 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 8 16.5. 9.6.2.2.5.2
Adjustment factors
For temperatures above 100°F and/or the use of a material other than ASTM A 744 - Grade CF8M , the loads in Table 9.6.2.2.1 should be reduced by multiplying them by the proper adjustment factor from Table 9.6.2.2.3. For intermediate temperatures not shown in Table 9.6.2.2.3, linear interpolation is permitted.
Temperature and material adjustment
Adjustment of allowable load values is required if any of the following occur: 1) Temperature is above 100°F 2) The pump material construction is not ASTM A 744- Grade CF8M

Scope
Nozzle load effects on single-stage double suction and two-stage horizontal axial. split case pumps. Discharge nozzles 2 in. through 10 in. with class 125 and 250 flanges per ANSI/ASME 816.1. Casings made of cast iron and mounted on a fully grouted baseplate by four bolts. 9.6.2.3.2
Description
Testing of nozzle loads on the above described pumps have shown that mis-alignment between the pump and driver shaft occurs from movement of the casing relative to the baseplate. The amount of loading that result in movement depends on the sizes of hold-down bolts, the amount of torque applied to the bolts and the grade of bolts. See Table 9.6.2.3.1 The shown nozzle loads are for those applied to castiron casings mounted on machined mounting surface(s} of carbon steel baseplate. The loads are for Grade A ASTM A307 bolts with no lubrication to the bolt threads. Calculation of stress in the pump suction or discharge nozzle show that such stress may also limit nozzle loads. See Table 9.6.2.3.2. 9.6.2.3.3
9.6.2.3.5
Casing hold-down bolts
The maximum allowable tensile stress for the holddown bolts is 90% of ASTM A 307 Grade A yield strength. The maximum allowable shear stress for the hold-down bolts is 25% of ASTM A307 Grade A yield strength . Fasteners used for hold down bolts must have a yield strength greater than or equal to ASTM A307 Grade A fastener yield strength. The casing shall be bolted to the baseplate by four bolts and sufficiently tightened to prevent slippage or movement relative to the baseplate. Refer to API 686 , Appendix E, for the required torque values. It may be necessary to arrange for periodic tightening of the bolts to maintain the required torque. It can be argued that some of the bolts may be against the wall of the bolt hole at initial installation. It can also be argued that with small bolts, the shank of the bolt may bend as the side force overcomes the friction force. To keep the presentation uncomplicated, friction force will be the criterion.
Driver and pump Assumed effect of nozzle loading:
The allowable radial movement of the pump shaft at the coupling hub due to nozzle loading shall not exceed .005 in. parallel to the initial alignment. Axial movement of the pump shaft at the coupling is not considered. 9.6.2.3.4
Limiting factors
Tests have shown that the limiting factors are not due to: a}
Bending of the shaft at the seal chamber or stuffing box
b)
Internal distortion of parts
Limiting factors are due to: a) Tension stress of the bolting of the casing to the baseplate
Forces in the X and Y directions, and the moments about the Z-axis · (see Figure 9.6.2.3.1 ), are assumed to be distributed equally to all the holddown fasteners in all four feet. Movement of the pump occurs when the force overcomes the static horizontal friction force on all four feet induced by the torque of the hold-down bolts. The static weight of the pump is relatively small compared to the force induced by the torque of the bolts. Forces in the Z direction, and moments about the Xor Y-axis, are assumed to be distributed to fasteners in two feet resulting in yielding of the fasteners. The yielding load is the difference between the torque stress applied bolts and the yield stress of the fastener. It is also. assumed that the piping does not provide restraint to pump movement.

Horizontal overhung slurry pumps can be grouped into two major categories, lined-casing and unlined casing. Lined casing pumps usually have casing shells of non-wear-resistant composition with a wear-resistant liner (elastomer, hard metal, or a combination). The liner is designed to wear, while the shells are not intended to wear (with recommended maintenance). Unlined-casing pumps are of more traditional design, having casings of wear-resistant metal with heavy wall thickness designed for sacrificial wear.

HI Centrifugal and Vertical Pumps for Allowable Nozzle Loads- 2001 pump, the allowable nozzle load are reduced. Standard nozzle loads are not applicable to this design. The user should rely upon the pump manufacturer to establish acceptable nozzle loads for each pump design and define minimum casing wall thickness for each design.
fx, fY' and 12 are .actual applied nozzle forces in their respective coordinate direction.
Lined-casing type pumps are designed to retain full casing strength throughout the life of the product (as long as the liners are replaced before wear is allowed to penetrate the liner and affect the shells). This means allowable nozzle loads are much more predictable. However, with the great variations of pump design among manufacturers, and within any single manufacturer, a standard approach to establishing allowable nozzle loads is not appropriate. The user should rely upon the pump manufacturer to establish acceptable nozzle loads for each pump design.
Fx, FY' and F2 are tabulated maximum permissible nozzle forces in their respective coordinate direction.
9.6.2.5 9.6.2.5.1
Vertical turbine short set pumps Scope
This standard deals solely with the maximum permissible loads on a vertical pump when the pump and system flanges are rigidly connected. It does not cover flexible or deformable connections such as bellows or flexible spool pieces. The choices of vertical pump configurations are numerous and their construction details are as varied as the pump manufacturers who produce them. Consequently, the scope of the analysis of forces and moments on vertical pump flanges has been restricted within certain limits, as defined below: Flange sizes between 2 and 36 inches. This excludes larger pumps, which are frequently custom built and require technical coordination between the manufacturer and user. Submerged suction with either above pump base (floor) or below pump base (floor) discharge short set pumps. Pump units that supply clear liquids with a maximum specific gravity of 1 .2. Vibration limits shou ld not be used in conjunction with this standard, unless agreed to by all involved parties. This is because external loads applied can make certain vibration levels unattainable.
mx, mY' and mz are actual applied nozzle moments in their respective coordinate direction.
Mx, MY' and Mz are tabulated maximum permissible nozzle moments in their respective coordinate direction. ly and
12
are the flange centerline distances to the baseplate centerline in the y and z direction respectively.
0 is the nominal discharge nozzle size.
A is the distance from the discharge case to pump base (applicable only on below pump base discharge pump). Fx', Fy'· F2 ' , Mx', My'· and M2 ' are the maximum permissible nozzle loads after compensation for centerline distance, temperature, and/ or material variation . P1ab is the pressure rating of 150# carbon steel flange at 100°F from ANSI/ASME 616.5. Pnew is the pressure rating of the actual material at a given temperature from ANSI/ASME 616.5. 9.6.2.5.3
Methodology
Consider the x-y-z coordinate system origin to be at the discharge flange face centerline. The included tables of allowable loads show maximum individual loads for each coordinate direction on each flange. The loads are to represent both forces and moments. Each value in the tables represents the maximum allowable load in a particular direction acting alone. For cases in which more than one load is applied simultaneously, the following formula should be used:

Appendix C shows examples to illustrate usage of the prev1ous equations. Criteria for the maximum individual loads IS based on operating expenences with extsring products and the following: Deflection - The max1mum allowable lateral deflection at the stuffing box area is 0.002 inches. This restriction on deflection is because most mechanical seals are designed to operate within these limits.
(Eq. 12) No contact between moving and stationary pans (i.e .. impeller and bowls). The max1mum allowable lateral deflection at the pump bowl is 0.002 inches.

Derati ng Loads On comparing temperature and material parameters with the scope of this standard. it IS found that thrs rs an applicable scenario. Since CF8M IS the matenal. and temperature of operat1on is less than 1OO"F. no adjustment of the allowable table loads is necessary. Also. since the unit is mounted on a fully grouted metal baseplate with anchor bolts. no adjustment of the allowable table loads is necessary.

Tile applied loads are compared to the allowable loads below. Derating Loads
1)
Upon comparing operating temperature and material parameters with the scope ol this standard , it IS found that this is an applicable scenario. Since Alloy 20 is the rnatenal and operation is occurring at 400 F. an adjustment of Table 9.6.2.2.1 loads is necessary. Using Table 9.6.2.2.3, a derating value of 0.67 1s found under Alloy 20 at 400 F. Derate the values 1n Table 9.6.2.2.1 as shown below. Line in Table 9.6.2.2.1 before derating :
