Multistage Jockey Pump
A jockey pump is designed to maintain pressure in a fire protection piping system to an artificially high level. The operation of a single fire sprinkler will cause a pressure drop sensed by the automatic controller, prompting the main fire pump to start.

Frequently Asked Questions
Q: What makes a fire pump different from other kinds of pumps?
A: Fire pumps meet stringent NFPA 20, UL, and FM requirements for extreme reliability. They must maintain specific pressure levels (at least 65% pressure at 150% rated flow) even under difficult conditions like a 15-foot lift.
Q: What is the typical lead time for a fire pump?
A: Typical lead times run 5-8 weeks from the release of an order, depending on the specific model and customization requirements.
Q: How are engines and motors sized for fire pumps?
A: Motors and engines are sized according to UL/NFPA 20 standards to operate at any point on the pump curve without exceeding the service factor. They are often sized for a 1.15 service factor since they don't run continuously.
Q: What is the easiest way of determining pump rotation?
A: Standing at the motor facing the pump, it is right-hand (clockwise) if suction is from the right and discharge is to the left. Rotation depends strictly on the vantage point.
Q: Do I need to worry about NPSH in fire pump applications?
A: Rarely. Fire pumps typically require a "flooded suction" where water arrives via gravity to ensure a 100% prime at all times, which is critical for fire emergency readiness.
Q: Can a flow meter loop substitute a test header?
A: While it tests hydraulic performance, a closed loop doesn't test the actual water supply integrity. For initial start-ups, flowing water through hoses and Playpipes is recommended to ensure the system is free of obstructions.
