1. P045, P062, P075, P100, P137, P150, P200 only:
a) Place the clamp O-ring on the clamp ring, and install it on the motor adapter.
Press firmly to ensure a tight seal.
b) Place the barrier O-ring on the motor barrier and install it on the motor adapter.
c) Install the impeller sha, aligning the flats on the sha with the ones in the motor
barrier. Make sure the impeller sha is completely seated in the motor barrier.
2. Assemble the impeller thrust ring, the impeller drive assembly, and the impeller
bushing.

3. Place the housing O-ring in the groove on the pump housing and apply an oil-free
lubricant.
4. Install the pump housing onto the pump, making sure the discharge is in the correct
orientation for the installation.

Description
Assemble the impeller bushing.
NOTE The P030 impeller as-
sembly has the thrust ring and
drive assembly included within
it.
Assemble the impeller thrust ring, the im-
peller drive assembly, and the impeller
bushing.
5. Hold the pump housing with one hand, install and finger-tighten two bolts or screws
and washers (if present) in opposite locations.
6. Install the remaining pump housing fasteners and finger-tighten.
7. Use a socket wrench or screwdriver (depending on fasteners) to tighten all bolts
evenly using a star pattern.

Suggested remedy
Check the pipe connections
and tighten the seals.
Ensure the pump head is
filled with fluid before start-
ing.
Check the application re-
quirements; a larger pump
may be required.
Open the suction and dis-
charge valves.
Check the fluid mixture con-
centrations.
Ensure the proper inlet
pressure. The pump should
be either below water lev-
el or in a fully pressurized
loop.
Check the inlet strainer and
pump lines, and remove de-
bris.
Check the wiring to ensure
the installed configuration
matches wiring diagram on
the pump.
Bleed the air out of the sys-
tem using an automatic
bleeder or manually open a
bleeder line at the highest
point.
Check the application re-
quirements; a larger pump
may be required.
Check the application re-
quirements; a smaller pump
may be required.
Check the wiring to ensure
the installed configuration
matches the wiring diagram
on the pump.
Check the pipe connections
and tighten the seals.
Check the generator power
output to ensure it is main-
taining the proper voltage.
Check the fluid mixture con-
centrations.
Ensure the proper inlet
pressure is maintained.
Check the inlet strainer and
the pump lines, and remove
debris.
