Fire pumps

Our fire suppression pumps can be powered by diesel, electric, or both motors. We have a wide variety of fire suppression pumps, from small, basic electric-motor pumps to larger diesel-electric units. The pump is connected by a supply valve to a line connected to a water supply (such as a lake or pit). The pump supplies water under high pressure to sprinklers and fire hydrants. Each pump is tested for its intended fire-suppression use. Our standard units are designed for clean, freshwater use. However, we also build special units for saltwater, offshore use employing anti-corrosive materials. The principal code regulating fire pumps in the United States is the National Fire Protection Association’s code NFPA-20.

A jockey pump is a small pump connected to a sprinker or fire hydrant pipe network and is used to maintain high line pressure as sprinklers begin to activate. Automatic controls monitor line pressure and turn on the jockey pump when needed. The jockey pump is essentially part of the control system for the fire-suppression network.

Characteristics

  • Applications

    We have a wide variety of fire suppression pumps, from small, basic electric-motor pumps to larger diesel-electric units. Our standard units are designed for clean, freshwater use. However, we also build special units for saltwater, offshore use employing anti-corrosive materials. WARSON fire pumps provide superior performance for general industrial facilities, construction, commercial facilities, power plants, and offshore platforms, and are all compliant with NFPA 20 requirements.

    Advantages of fire pumps:

    They do not require priming or purging since the impeller is always submerged beneath the water supply. Startup is automatic and does not require supervision.

    When equiped with vertical motors, our vertical pumps require 75% less floorspace compared to a horizontal pump.

    Suitable operating curves and that do not have large changes in the flow of the pump due to considerable changes in line pressure.
