Hubbell’s Model HJ601 Jockey Pump Controllers are intended for across-the-line starting of squirrel cage motors, 1/2 Hp at 120 V and 3/4 Hp at 120 V. The controller is for fire protection system applications where it is desirable to maintain uniform system water pressure by the use of an automatic pressure maintenance pump.Model HJ601 Jockey Pump Controllers serve overall system efficiency by detecting minor fire protection water system leakage. By bringing jockey or make-up pumps on line, they maintain pressure within set point limits without unnecessary cycling of the main fire pump. These controllers come standard in a UL type 3R enclosure with one point latch, flanged door, and padlockable.
