Jockey Pump Systems
Jockey Pump

A jockey pump maintains pressure in a fire protection piping system. It prevents the main fire pump from starting unnecessarily due to small leaks or pressure drops, acting as a critical component of the fire pump's control system.

Frequently Asked Questions
What makes a fire pump different from other kinds of pumps?
Fire pumps meet stringent NFPA 20, UL, and FM requirements for reliability under extreme conditions. They must produce specific flow rates and maintain at least 65% of rated pressure at 150% flow, even at a 15-foot lift. Casings must withstand hydrostatic tests of three times the maximum operating pressure.
What is the typical lead time for a fire pump?
Typical lead times range from 5 to 8 weeks from the release of an order, depending on specific configuration and requirements.
How are engines and motors sized for fire pumps?
Motors and engines are sized according to NFPA 20 standards to operate at any point on the pump curve without exceeding the service factor. They are designed to handle flow even beyond 150% of rated capacity.
Do I need to worry about NPSH in fire pump applications?
Rarely. Fire pumps require a "flooded suction" where water arrives via gravity. This ensures 100% priming at all times, which is critical for fire emergency response.
Can I use a flow meter loop as a substitute for a test header?
A flow meter loop is practical for testing hydraulic performance but does not test the actual water supply integrity. For initial start-ups, flowing water through hoses and playpipes is highly recommended to expose any supply obstructions.
What is the easiest way of determining pump rotation?
For a horizontal split-case pump, facing the pump from the motor side: it is right-hand (clockwise) if suction is on the right and discharge is on the left.
