COS Series pumps are Horizontal Double Suction Split Case Centrifugal Stainless Steel Sea Water Pump, they are single-stage, double suction, horizontally mounted, applied for general water supply, water booster service, municipal waterworks, condenser cooling, hot water circulation, industrial water service, high building water supply, chemical plant, power plants etc.

It is specially design for corrosive liquid like the acid liquid, sea water as well as mining water with corrosiveness. All the wet parts choose stainless steel material, which ensure the working life of pumps while handling corrosieve liquids.

COS series Split case centrifugal sea water pumps feature a single double suction or two single suction impellers supported between bearings. The casing is split axially, with opposing suction and discharge flanges, greatly simplifying maintenance. With balanced bearings and a robust overall design it’s not uncommon to find a horizontal split case pumps still in use after 30 years of service.Suitable for electric or diesel engine, our COS series split case sea water pump duties range from 50m3/h to 20,000m3/h, head range from 15m to 220m.

FEATURES
* Axially split casing – rotating element can be removed without disturbing pipework
* Exceptional hydraulic efficiencies
* Double and single entry back to back impellers reduce end thrust, increase efficiency and bearing life
* Modular design for maximum interchangeability. Multiple impeller selections
* Stainless steel impellers and shaft as standard
* Internal high efficiency coating as standard
* Cartridge mechanical seals as standard
* Double row thrust bearing
* Wide operating range and extended bearing life
