Double Suction Horizontal Split Case Centrifugal Pump COS80-210 (90-200m3/h @ 30-60m)
COS Series pumps are double suction horizontal installed split case centrifugal pump, they are Single stage, axially split casing, double-suction pumps. Double entry radial impeller has hydraulic thrust compensation. Suction and discharge flanges are along the same line. Upper body is lighter than the lower body and joins it in such a way that it is easily assembled. Double suction pumps have the advantage of low NPSH (net positive suction head) features.
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
* Reduced efficiency degradation
