Fire pumps ensure fire sprinklers operate effectively by maintaining adequate water pressure during emergencies, while jockey pumps maintain baseline pressure within the sprinkler piping so the main fire pump controller can detect drops and activate automatically.
If you have a commercial or industrial building that needs sprinklers for fire protection purposes, you might be wondering if a fire pump should be part of the design. It’s a very reasonable question. The primary purpose of a fire pump is to ensure fire sprinklers work the way they’re supposed to by keeping water pressure at an adequate level. Without a pump, water might slowly trickle onto a fire, doing little to extinguish the blaze and allowing property to be destroyed even with carefully installed sprinklers.
How Fire Pumps and Jockey Pumps Work
- Fire Pumps: These systems feature an electric or diesel-powered engine that kicks into gear when sprinkler water pressure drops below a certain threshold—typically when multiple sprinklers activate simultaneously or when firefighting teams hook up their hoses.
- Jockey Pumps: A jockey pump is a small portion of a fire pump’s control system that maintains pressure within the sprinkler system piping to an artificially high level. This ensures that when an appreciable pressure drop occurs, the main fire pump’s automatic controller can easily detect it and start up the pump.
Quick Reference: Fire Pump vs. Jockey Pump
| Pump Type | Primary Operational Function | Key Trigger / Mechanism |
| Main Fire Pump | Provides high-volume water pressure to douse active fires | Activated when system pressure drops below threshold |
| Jockey Pump | Maintains baseline artificial high pressure in sprinkler piping | Runs periodically to counteract minor pressure leaks and keep lines primed |
Types of Buildings Where Fire Pumps Are Used
- High-Rise Buildings: Sprinkler heads on top stories need extra help creating the required water pressure to douse flames, making pumps essential for multistory structures.
- Storage Warehouses: Large expanses without walls or doors have higher water pressure demands as fires spread rapidly across open spaces.
- Buildings with Water Storage Tanks: Buildings supplied by onsite storage tanks rather than direct city water mains require dedicated pumps to establish proper water pressure.
