DISCHARGE
VALVES DIFFI-
CULT TO OPER-
ATE Lack of lubrication • Recommended weekly lubrication of discharge and suction valve.
• Use a good grade petroleum based silicone grease.
• Foe Hale Products, SVS Valves, etc., use Never-Seize ® White
Food Grade with PTFE.
• Refer to separate valve manual for addition information.
Valve in need of
more clearance for
operation • Multi-gasket design allows additional gaskets fro more clearance
and free operation.
Note: Adding too many gaskets to the valve eventually causes leakage.
WATER IN PUMP
GEARBOX Leak coming from
above the pump • Check all piping connections and tank overflow for possible spill-
age falling directly onto the pump gearbox.
• Repair accordingly.
Leaking mechanical
seal • Inspect the oil seal and replace as needed. If the oil seal checks
OK, then the mechanical seal may need to be replaced.
• If a mechanical seal is installed there must be no leaks. See Sec-
tion 6 Repair, heading “Mechanical Seal Assembly” on page 74.
ROTATION
SYMPTOMS
(Reduced pressure
60-100 PSI [4.1-
6.9BAR] and
reduced flow.)
Wrong impeller
installed • Verify the new impeller vanes are oriented the same as the old
impeller before installing. (See Figure 2-6: “Pump/Engine Rota-
tion,” on page 3-19.)
• Refer to relief / sensing valve manual and follow maintenance
instructions for disassembly, cleaning and lubrication.
Impellers installed
backwards (two-
stage pump) • Verify the impellers are in the correct order - p/n: 016-0280-00-0 is
installed closest to the gearbox in an “Engine Rotation” applica-
tion and CLosest to the front in a “Opposite Engine Rotation”
application.
Wrong application
attempted • The pump was installed on an application for which it was not
intended, i.e., front mount vs. rear mount.
