Some of the most annoying problems with fire pump systems are related to the jockey pump controller. They can chatter, trip circuit breakers or fuses, cause water hammer, and they can even overpressure the system. These problems are all solved with a Variable Speed Jockey Pump Controller.
With the through door display, you can monitor the following: system pressure, motor volts, amps, power, and even the motor speed. See attached Jockey Controller PDF Brochure.
