Double Suction Split Case Fire Fighting Water Pump COS-F200-670 (2000-3500gpm 80-160m)

Description

A fire fighting water pump is a centrifugal pump which is used for pumping fire-fighting water. Fire-fighting pumps can be designed for transportable use (e. g. on fire-fighting vehicles or as portable fire pumps) or for stationary use (e. g. hydrants, sprinkler systems).

The XSF series Horizontal Split Case Fire Fighting Water Pumps are engineered for reliable operation upon stationary use. All fabricated parts are standardized and accurately machined for true alignment, increasing overall durability. Precision balancing of all rotating components provides mechanical dependability, reliable operation and minimal maintenance. Impellers are constructed with double inlets that practically eliminated end thrust while boosting operating efficiency.

Features
* Exceptional hydraulic efficiencies
* Double entry reduce end thrust force, increase efficiency and bearing life
* Stainless steel impellers and shaft as standard
* Reduced efficiency degradation
* Comply to FM and/or UL standards (NFPA 20, UL448 and FM1311)
