A jockey pump, also known as a fire pump jockey pump, plays a crucial role in fire protection systems by maintaining consistent pressure and preventing unnecessary activation of the main fire pump. While many assume that a pump jockey runs continuously, this is not the case. Instead, it operates automatically based on pressure fluctuations within the system. Let’s dive deeper into the function, activation triggers, and key benefits of a fire jockey pump in a sprinkler system.

A fire jockey pump works alongside the main fire pump to ensure the fire protection system remains pressurized at all times. When small drops in pressure occur due to minor leaks, temperature fluctuations, or normal system operation, the sprinkler jockey pump activates to restore the pressure. This prevents the main fire pump from cycling on and off unnecessarily, which extends its lifespan and ensures it is only used for actual fire emergencies.
A fire pump jockey pump is triggered under several conditions:
· The most common reason a jockey pump turns on is a drop in system pressure. This can be caused by small leaks in pipes, fittings, or sprinkler heads.
· When a single sprinkler head discharges water, the sprinkler jockey pump compensates for the pressure drop to maintain system integrity before the main fire pump engages.
· Air temperature fluctuations can cause expansion and contraction in the pipes, leading to slight pressure variations. The fire jockey pump automatically corrects these changes.
· During fire system inspections, technicians may deliberately trigger the jockey pump to verify that it is functioning properly.
· Issues such as a malfunctioning check valve or manual valve adjustments can alter system pressure, prompting the jockey pump to activate.
No, a fire jockey pump does not run continuously. It only activates when the system detects a drop in pressure and turns off once the preset pressure is restored. This energy-efficient operation ensures that the pump is only used when necessary, reducing wear and tear.
There are three main types of fire and jockey pumps, each suited for different applications:
· Cost-effective and compact
· Requires a pressure relief valve
· Highly reliable with small footprint
· Easy to maintain
· Used when the water supply is insufficiently pressurized
· Installed within a water source
· Must be a centrifugal pump but does not require fire pump certification
· Should include a check valve, isolation valve, and independent pressure sensing line
· No need for standby power, though backup generators or battery systems are recommended
· Should be set at least 10 PSI higher than the main fire pump to prevent unnecessary fire pump activation

Purity’s fire pump jockey pump offers industry-leading advantages over competitors:
· High-pressure multistage pump with a compact vertical design
· Durable mechanical seals for leak-free, long-lasting operation
· Over 15 years of experience in manufacturing certified multistage pumps (CE-certified)
A fire jockey pump is essential for maintaining steady pressure in fire protection systems, but it does not run continuously. Instead, it activates only when needed, preventing the main fire pump from unnecessary operation. Proper selection, installation, and maintenance of a sprinkler jockey pump improve fire system efficiency and reliability.
