CEMarkedTORNATECH
A jockey pump controller controls the jockey (pressure maintenance) pump used to maintain pressure in fire pump systems. According to Tornatech, the jockey pump prevents the main fire pump from starting unnecessarily because of small leaks in the sprinkler installation. Motor power, system pressure and cut-in settings are evaluated together when selecting a jockey pump controller.
The Tornatech JPLT-B is supplied with a ViZiLT operator interface mounted on the front door. Start and stop pressures, timers and the unit of measure (psi or bar) can be set without opening the door. The display shows system pressure, set points, operating status, motor overload information, number of starts and a non-resettable run-hour counter.
The power circuit consists of a horsepower-rated disconnect switch, a thermal-magnetic motor protector and a motor contactor for across-the-line starting. The fuseless motor starter is operated by a rotary handle that can be padlocked and is interlocked with the door.
The controller senses pressure with a 316 stainless steel pressure transducer operating in the 0–600 psi range and is offered for jockey pump motors from 0.25 to 25 HP. The JPLT is listed under UL 508A.
