Pompa Air Vertical Multistage

C.R.I. Vertical Multistage centrifugal pumps (MV Series) are non-self priming, axial suction and delivery type available with DIN standard port connections. All components like impeller, diffusers, & shaft of these pump are made of corrosion resistant AISI stainless steel and designed to deliver the best possible hydraulic efficiency. As the diffuser chambers, impellers, shaft & pump base (casing are made of high grade stainless steel S.S 304/316, these pumps can be used to pump aggressive water and are quite hygienic to use in drinking water systems too. ‘O’ rings and gaskets prevent leakage at the intermediate casing during high pressure. The replacement of the seal can even be done in the installed position without removing the pump from the booster system. These pumps are reliable, easily serviceable and used in water boosting units to get trouble free service for years together

C.R.I. Multistage Vertical  pumps are powered by a totally enclosed fan cooled, A.C. induction motor, suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure and rigidly  locked in the frame. Dynamically balanced rotor ensures vibration and noise free operations. The varnished impregnated windings made of enameled copper wire offer excellent resistance.

Shaft of ample size made of quality steel and precisely ground is used for transmitting the rated horsepower. Construction of motor frames and usage of quality materials result in high performance and low  temperature rise thereby increasing the life cycle of the motor. Thermal over load protector is incorporated in all single phase motors. These pumps require an adequate control system.

Applications :

  • Pressure Boosting
  • Reverse osmosis system
  • Fire fighting systems
  • Industries & General water supplies
  • Boiler feed
  • HVAC & Chilled water systems
  • High pressure washing & cleaning
  • Irrigation
