Why does my Crane Water Pump deliver insufficient capacity?
- C
  Christie MillerAug 13, 2025
  The Crane Water Pump might deliver insufficient capacity because of several reasons, including incorrect voltage, excessive inflow, or the pump not being properly sized for the application. The discharge could be restricted, the check valve might be stuck closed or installed backward, or a shut-off valve might be closed. The impeller could be jammed, loose on the shaft, worn, or damaged, or the impeller cavity or inlet might be plugged. Also, the pump may be airlocked or running backward.

  The Crane Water Pump might not turn off because the float movement is restricted, or the switch won't activate the pump or is defective. Other potential causes include excessive inflow, the pump not being properly sized for the application, the pump being airlocked, or the H-O-A switch on the panel being in the “HAND” position.

  If your Crane Water Pump isn't running, there could be several reasons. First, check all electrical connections to ensure they are secure, and inspect the fuse or breaker for any interruptions in power. An electrician can measure the current in the motor leads. If the current is within ±20% of locked rotor Amps, the impeller is likely locked. If the current is zero, the overload may be tripped. Remove power and allow the pump to cool before rechecking the current. Also, make sure the liquid level is at least at the suggested turn-on point. The float movement may be restricted. Reposition the pump or clean the basin to provide adequate clearance for the float. If the switch won't activate the pump or is defective, disconnect the level control and use an ohmmeter to check if it shows zero oh...
