Pressure Boosting Pumps

Multistage Vertical Centrifugal (Inline) Pumps MV series

C.R.I. Multistage Vertical Centrifugal (Inline) Pumps MV series are non self priming with mechanical shaft seal and bearings lubricated by the pumped liquid. All components like impellers, diffuser and shaft of these pumps are made of corrosion resistant stainless steel and designed to deliver the best possible hydraulic efficiency. These pumps are powered by a totally enclosed fan cooled A.C. induction motor, which is 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
