Service
Never run pump dry. Running pump without water may
cause pump to overheat, damaging seal and possibly causing burns to per-
sons handling pump. Fill pump with water before starting.
Never run pump against closed discharge. To do so can boil
water inside pump, causing hazardous pressure in unit, risk of explosion
and possibly scalding persons handling pump.
PRIMING THE PUMP
A tee installed in the discharge opening of the pump, and provided with a
priming plug at the top position, will enable you to fill the pump with liq-
uid. Once filled and the priming plug replaced, the pump will prime. The
pump should prime itself time after time, as long as the built-in check valve
functions.
MAINTENANCE
Little or no maintenance to pump is required other than possible replace-
ment of shaft seal after a reasonable period of operation (see Page 10).
Lubricate motor according to motor manufacturer's in-structions. Periodic
greasing is required for most motors.
PUMP STORAGE
Drain pump to prevent freezing.
Keep motor dry and loosely covered. Do not wrap with plastic sheeting;
trapped moisture could cause corrosion or insulation deterioration.
NOTICE: A good rust inhibitor in the liquid end of cast iron pumps is rec-
ommended to prevent excessive corrosion.
PUMP START-UP AFTER STORAGE
Replace all drain plugs and close all drain valves in system.
Be sure all connections are tightly sealed.
After initial check is made, fill pump according to "Priming the
Pump," above.
SHAFT SEAL REPLACEMENT
IMPORTANT: The highly polished and lapped faces of the seal are easily
damaged. Follow instructions and handle the seal with care.
Be sure unit is grounded and power disconnected before
attempting any work on pump or motor.
