• As depicted in Figure 1, place the baseplate on wedges, 

locating two wedges at each foundation bolt location. A gap 
of ¾" to 1½" (19 mm to 64 mm) is recommended between 
the baseplate and the foundation for grouting. Adjust the 
wedges as necessary to level the baseplate.

• Inspect baseplate for any distortion, and adjust as neces-

sary. Make sure that any necessary fi nal coupling alignments 
are possible within the motor movements and shim limits. 
Tighten the 4 foundation bolts fi nger tight.

• Build a dam around foundation and pour grout under the 

baseplate, insuring that the areas under the pump and  
motor are fi lled completely.

• Allow grout to harden for 48 hours before tightening  

4 foundation bolts.

• For maximum pump capacity, piping should not be smaller 

than the pump suction and discharge.

• To minimize pipe friction losses, avoid unnecessary pipe 

and fi ttings.

• All piping MUST be independently supported and MUST 

NOT place any piping loads on pump.

NOTICE: DO NOT FORCE PIPING INTO PLACE AT  
 

PUMP SUCTION AND DISCHARGE    

 CONNECTIONS.

• Short and direct suction piping is recommended. For  

suction lifts of over 10' (3 m) and liquid temperatures over 
120° F (49° C), consult pump performance curve for net 
positive head required (NPSH

R

).

• If a pipe size larger than the pump suction is required, an 

eccentric pipe reducer, with the straight side up, MUST  
be installed at the pump suction.

• If the pump is installed below the liquid source, install a full 

fl ow isolation valve in the suction for pump inspection and 
maintenance.

NOTICE: DO NOT USE THE ISOLATION VALVE TO  
 

THROTTLE PUMP. THIS MAY CAUSE LOSS  

 

OF PRIME, EXCESSIVE TEMPERATURES  

 

AND DAMAGE TO PUMP, VOIDING    

 WARRANTY.

• If pump must be installed above the liquid source, the  

following MUST be provided:
• To avoid air pockets, no part of the piping should be 

above the pump suction connection.

• Slope the piping upward from liquid source.
• All pipe joints MUST be airtight.
• Use a foot valve ONLY if necessary for priming or to 

hold prime during intermittent duty.

• The suction strainer or suction bell MUST be at least  

3 times the suction pipe diameter area.

• Insure that the size and minimum submergence over suc-

tion inlet is suffi cient to prevent air from entering pump 
through a suction vortex. See Figures 2 through 5.

• Install a check valve, suitable to handle the fl ow and liquids, 

to prevent backfl ow. After the check valve install an   
appropriately sized gate valve to be used to regulate the 
pump capacity, pump inspection and maintenance.

• When required, the pipe increaser should be installed be-

tween the check valve and the pump discharge.

• All wiring and grounding connections must be in accor-

dance with Local and National Electrical Code require-
ments.

• Use only stranded copper wire to the motor and ground. 

Wire size MUST limit the maximum voltage drop to 10%  
of  the motor nameplate voltage, at the motor terminals. 
Excessive voltage drop may affect performance and will 
void the motor warranty.

• Single phase motors supplied by Goulds, have built in ther-

mal overloads. Other motors not so equipped MUST  
use a properly sized contactor and overload. Fuses are 
permissible.

• Three phase motors require all leg protection with properly 

sized magnetic starters and thermal overloads.
