What Is a Jockey Pump and Why Is It Important?

A jockey pump is a small, auxiliary pump used in fire protection systems to maintain water pressure within the fire sprinkler or hydrant system. Its primary purpose is to keep the system pressurized and ready for action without unnecessarily activating the main fire pump, such as an electric or diesel fire pump.

Key Features of a Jockey Pump

• Size: Smaller in capacity compared to the main fire pump.
• Operation: Runs automatically when the system detects a drop in pressure due to minor leaks or system testing.
• Control: Works with pressure switches or control panels to maintain a consistent pressure level.

Why Is a Jockey Pump Important?

1. Pressure Maintenance:

   • Fire protection systems need a constant, specific pressure to function effectively. A jockey pump ensures this pressure is maintained.

2. Prevents Main Pump Overuse:

   • Without a jockey pump, minor drops in pressure could activate the main fire pump frequently, leading to unnecessary wear and tear and higher operational costs.

3. Improved System Reliability:

   • By keeping the system pressurized, a jockey pump ensures that sprinklers and hydrants are ready to operate immediately during a fire emergency.

4. Cost-Effectiveness:

   • Operating a smaller jockey pump is more energy-efficient and cost-effective than using the main fire pump for minor pressure adjustments.

5. Compliance with Standards:

   • Fire protection standards, such as NFPA 20, often recommend or require jockey pumps to ensure the system remains pressurized and operational.

In summary, a jockey pump plays a vital role in the reliability and efficiency of fire protection systems, acting as a safeguard to ensure the system is always ready to respond to a fire.
