pumps must be used with the proper size
and type of motor starter to ensure protection against damage from low voltage, phase failure, current imbalances,
and overloads. The overload should be sized to trip at the full-load current rating of the motor.
OPERATION
Priming
WARNING! Risk of explosion and scalding.
Do not run the pump with the discharge valve closed; the water in the pump may boil, causing risk of
explosion and steam burns to anyone nearby.
WARNING! Risk of electric shock.
Can shock, burn or kill. Disconnect all power to the pump before servicing or working on the pump. Make
sure that the power is locked out and that the pump cannot be accidentally started.
NOTICE: Under no circumstances should the pump be operated without flow through the pump. Never operate the
pump dry.
Operation of closed system or open system with the liquid level above the pump priming plug.
1. Close the discharge isolating valve and loosen the needle valve located in the assembly in the pump head
(figure below). Do not remove the needle valve.
NOTICE: On PVM(X)2/4 models, remove the couple guard for access to the vent plug.
CAUTION! Risk of flooding.
Can cause personal injury and/or property damage. Watch
the direction of the priming plug and make sure that the
liquid escaping from it does not injure persons nearby
or damage the motor or other components. In hot water
installations, pay particular attention to the risk of injury
from scalding hot water.
2. Slowly open the isolation valve in the suction pipe
until a steady stream of liquid runs out the vent in
the priming pot.
3. Tighten needle valve to 25 inch-pounds. Completely
open isolation valves.
