Final Test Procedures 12–4
A jammed grinder may trip the circuit breaker or cause the overload protector to cycle and this
will cause the pump to cycle on and off and finally result in an alarm condition. A torn or worn
out pump stator results in a “runs but does not pump” condition and causes an alarm. Current
readings with a clamp-on amp meter will show 4.0 to 4.5 amps when the motor is running
without a load. Replace the stator and, if necessary, the rotor.
