3. Pump & Motor Installation
3.1 Installation of Pump, Motor & Base
The following guidelines should be observed for proper installation of the pump and motor
assembly:
A) The foundation area should be rigid and level for maintaining the alignment of the pump
with the system piping.
B) The pump and motor assembly must be securely fastened to the base, and the base must
be securely attached to the ground.
C) The pump and motor should be accessible for inspection and servicing.
D) The pump inlet (suction port) should be as close to the liquid supply as practical and
preferably below it.
E) The piping should be properly supported. DO NOT use the pump as a pipe hanger.
F) Install valves and unions to isolate the pump during maintenance.
G) Suction and discharge piping should be the same size or larger than the inlet and outlet
ports.
H) Clean piping as necessary to remove dirt, grit, weld slag, etc.
I) For further instructions on mounting or installing your pump, refer to the Hydraulics
Institute Handbook.
J) A positive displacement pump should have a pressure relief valve installed in the
discharge line. The relief valve should be the closest valve to the discharge port of the
pump and should bypass the discharge line back to the supply tank.
K) The maximum particle size capable of being passed by the pump is 37 microns. A filter
of at least 400 U.S. Mesh should be installed in the suction line. Concentration of solids
exceeding 1% is not recommended as wear rates will increase to unacceptable levels.
L) Clean the pump and motor periodically to prevent the build-up of dust.
NOTE: The Max Series pumps are close-coupled and no alignment procedures between the
pump and motor are needed.
