Double Suction Split Case Fire Fighting Water Pump COS-F250-600 (3000-5000gpm 90-120m)
The XSF series Horizontal Split Case Fire Fighting Water Pumps are engineered for reliable operation upon demand. 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.
The simple, split case design of these pumps allows for in-line service without disturbing piping while ensuring long, efficient unit life, reduced maintenace costs and minimal power consumption. Whether your fire pump application requires an electric motor, a diesel engine or vertical or horizontal orientation, these industry-approved pumps can be configured to meet your specific needs. These pumps are designed to operate with pressures from 5 Bar to 20 bar, even in excess of 22 bar and flows from 500 gpm to 5000 gpm.
Features
* Axially split casing – rotating element can be removed without disturbing pipework
* Exceptional hydraulic efficiencies
* Double entry reduce end thrust force, increase efficiency and bearing life
* Stainless steel impellers and shaft as standard
* Internal high efficiency coating as standard
* Wide operating range and extended bearing life
* Reduced efficiency degradation
* Comply to FM and/or UL standards (NFPA 20, UL448 and FM1311)
