valves are installed with their adjusting
ends toward the suction port. If bi‐rota
tional operation is required, a pressure
relief device must be provided for both
directions of flow. Operation without a
pressure relief valve or with an improp
erly installed relief valve could cause
the pump to explode, resulting in seri
ous injury or death to personnel.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Lock out incoming power to the
drive unit to ensure that the pump
will remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Close the discharge and suction
valve (if used).
An overheated pump can cause severe
burns and injury. If overheating occurs:
1. Stop the pump immediately.
2. Allow the pump to completely cool.
3. Refer to the instructions in this
manual before restarting the
pump.

guards in place over the rotating parts.
Exposed rotating parts can catch cloth
ing, fingers or tools, causing severe in
jury to personnel.
