What is the primary purpose of a jockey pump in fire systems?

The primary purpose of a jockey pump in fire protection systems is to maintain system pressure during non-operating conditions. Jockey pumps are smaller pumps that are installed to compensate for small leaks in the fire protection system and ensure that the pressure remains within the required range. These pumps operate automatically to maintain the pressure in the system, preventing unnecessary activation of the main fire pump and avoiding a drop in pressure that could impact the system's readiness.

In fire protection, maintaining adequate pressure is crucial because it ensures that the system can deliver the necessary water flow during an emergency. If the system pressure drops, it could lead to impairment of the fire suppression system, making it less effective when needed. The jockey pump therefore plays an essential role in ensuring the system remains operational and effective without unnecessarily starting the larger main pump unless there is a significant demand for water.

Circulating water through the system is not the primary role of a jockey pump; rather, that function typically pertains to other system components. Enhancing sprinkler pressure may occur as a result of maintaining system pressure, but it is not the direct aim of a jockey pump. Activating fire alarms is related to detection and alarm systems, which is a completely different aspect of fire safety.
