Jockey pump from TPMC automatically sustains system pressure at the setpoint during idle periods, preventing short-cycling of the main pump and ensuring immediate activation upon fire detection. Featuring rugged multistage impeller assemblies optimized for low-noise, high-efficiency continuous duty, these pumps deliver superior hydraulic performance, long service life, and reliable operation. The compact footprint simplifies installation in new or retrofit pump rooms.

Note:
1. The jockey pump is typically sized at 1-3% of the main pump capacity, with a shut-off pressure set approximately 10-20 psi (0.7-1.4 bar) above the main pump start pressure.
2. The pressure ranges shown represent the available performance envelope at nominal speeds. Actual performance curves and drive power selection are provided upon request for selected duty point. Contact TPMC for details.
