How do jockey pumps contribute to the energy efficiency of fire protection systems?

Jockey pumps contribute to the energy efficiency of fire protection systems by maintaining system pressure with minimal power consumption. Unlike main fire pumps, which are designed for high-flow, high-pressure scenarios, jockey pumps are smaller and use less energy, making them ideal for maintaining pressure during normal conditions without wasting power. Additionally, jockey pumps with variable speed drives (VSDs) further enhance efficiency by adjusting the pump’s speed to match the exact pressure requirements, reducing energy use and operational costs.
