6) If the base plate is un-grouted, nonmetallic, and is anchored
down, multiply the original values of Table 2 by 70%.
Compare these values with the Table 2 corrected values of
Step 2 above. Use the lesser of the two corrected values as the
Table 2 corrected values. Multiply the values of Tables 1, 3,
and 4 by 70%. If any of the values of the de-rated Table 2 are
lower than the corresponding values in the de-rated Table 1,
substitute the lower of the values into Table 1.
7) Solve the equation of Equation Set #1 using the corrected
allowable values of Table 1. The result for each of the twelve
equations must be less than 1.00 for an acceptable applica-
tion.
8) Solve the equation of Equation Set #2 using the corrected
allowable values of Table 2. The result must be less than 1.0 to
be acceptable.
9) Solve the equation of Equation Set #3 using the allowable (or
corrected values if the base plate is either non-metal or un-
grouted) values from Table 3. The result must be between –1.0
and +1.0 to be acceptable.
10) Solve the equation of Equation Set #4 using the allowable (or
corrected values if the base plate is either non-metal or un-
grouted) values from Table 4. The result must be between –1.0
and +1.0 to be acceptable.
11) Use the solution of equation 3(a) and the solution of equation
4(b) to solve equation #5. The result must be less than 1.0.
12) If all the solutions of all the equation sets result in acceptable
values, the loads are within acceptable limits.

Notes:
1) The loads shown in Tables 1 through 4 are for a pump
mounted upon a fully grouted metal base plate with anchor
bolts.
2) The loads given in Tables 1 through 4 are for pumps con-
structed of 316 Stainless Steel when operated between
–20°F. and 100°F.
3) The temperature for a corresponding allowable nozzle load
is the temperature of the pumped liquid.
4) For an individual(single) load, the value of the applied load
must not exceed the maximum allowable value, for that
location, given in Table 1. i.e. The applied load divided by
the allowable load must be less than or equal to 1.0.
5) For a combination of more than one force and/or moment,
the applied loads must not exceed any limit of any Equation
(Sets 2 through 5) or any table (2 through 4).
6) When combining loads, the absolute value of any individual
load must not exceed the value given in Table 1.
7) The loads in the tables must be multiplied by adjustment
factors when applicable. The lowest correction factor must
be applied when more than one adjustment factor is
involved. There are cases where one adjustment factor is
applied in Table 2 and another adjustment factor is applied
to Tables 3 and 4.
Adjustment of allowable loads is required for:
Pump constructed of a material other than 316 S/S.
Pumping Liquid at temperatures above 100°F.
The base plate is not grouted.
The base plate is nonmetallic.
INSTRUCTIONS FOR USE OF ALLOWABLE LOADS
1) Determine the applied nozzle loads from the suction and dis-
charge piping systems.
2) Use the correction factor from Table 5 for the pump material
and operating temperature. For intermediate temperatures not
shown in Table 5 linear interpolation is permitted. Multiply the
values in Table 2 (For the applicable pump size) by the correc-
tion factor to obtain the allowable values.
3) If the base plate is metal, fully grouted, and anchored, evaluate
the values of the de-rated Table 2 to see if any value is lower
than the corresponding value in Table 1. If so, substitute the
lower of the values into Table 1. No corrections are needed to
Tables 3 and 4. Go to step 7.
4) If the base plate is un-grouted metal that is anchored down, use
the corrected values of Table 2 from Step 2 above and 80% of
the values in Tables 3 and 4. After adjusting the values in
Tables 3 and 4, if the absolute values of any of them or the
adjusted values of Table 2 (from Step 2 above) are lower than
the corresponding values in Table 1, substitute the lower of the
values into Table 1. Go to step 7.
5) If the base plate is grouted, anchored, and non-metallic, multi-
ply the original values of Table 2 by 80%. Compare these cor-
rected values with the Table 2 corrected values of Step 2
above. Use the lesser of the two corrected values as the Table 2
corrected values. Multiply the values of Tables 1, 3, and 4 by
80%. If any of the values of the de-rated table 2 are lower than
the corresponding values in the de-rated Table 1, substitute the
lower of the values into Table 1. Go to step 7.
