CRI CENTRIFUGAL MONOBLOCK PUMPS

CENTRIFUGAL MONOBLOCK PUMPS

C.R.I’s Centrifugal monoblock pump’s volute chamber and impellers are carefully designed to give the best possible hydraulic efficiency and suction lift characteristics. Most modern and highly sophisticated machinery and technology are employed in the manufacture of these pumps using quality raw material, dynamically balanced impellers, seals and ball bearing to ensure long life. Dynamically balanced rotor ensures vibration and noise free operation. Shaft is made of quality steel, precision ground of ample size for transmitting the rated Horse power.

C.R.I. Automatic pressure booster systems comprises of Self priming jet pump (JTS / JTC – Series), Pressure tank, Mechanical Pressure switch & other accessories designed ingeniously for delivering optimal performance. This system eliminates the need of over-head tanks & float switch. The electro mechanical control device switches ON & OFF the pump automatically whenever the pressure reaches the minimum and maximum preset levels. It maintains uniform pressurized water in the pipelines suitable for all domestic applications.
