CRI Multistage Horizontal Booster Pump Set




 

C.R.I. Horizontal Multistage Centrifugal Pump Set are axial sunction and vertical radial delivery with theraded ports. The impellers, diffusers and shaft of these pumps are made of stainless steel and designed to deliver the best possible hydraulic efficiency. This pumpsets is a non-self priming horizontal centrifugal pumpsets with mechanical shaft seal and sealing is by means of a bellow mechanical seal.

 

 

These Pumpsets are powered by a totally enclosed fan cooled, AC induction motor, suitable for continuous duty. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. Dyanmically balanced rotor ensures vibration free and noise free operations. Shaft is made of quality stainless steel, precision ground of ample size for transmitting the rated horsepower. All single-phase pumpsets are incroporated with TOP. These pumpsets require a adequate starter/motor protection control panel.

 

Applications :

  • Domestic and industries water pressure boosting distribution

  • Small farms

  • Gardens

  • Pumping of clean liquid in industry

  • Car washing

 

 Salient Features :

  • High operating effciency resulting in lower power consumption

  • Good suction lift characteristics

  • Dynamically balanced rotating parts including rotor and impeller

  • Balanced and rigid construction

  • Single shaft ensures permanent & Correct alignment

  • inbuilt thermal over load protection in all single-phase pumpsets

 

Pumped Liquids : Clean, thin, non-aggressive, non explosive, clear, cold, fresh water without abrasives, solid particies or fiber having the following characteristics.
