CRI WASTE WATER SURFACE PUMPS

Waste Water Surface Pumps

C.R.I. “SM Series” Self-priming Non-Clog Monoblock Pump’s volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics. These pumps are powered by a totally enclosed fan cooled A.C. Induction motor. Motor stator is made of low watt loss silicon steel laminations assembled under pressure and rigidly locked in the frame. 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.

ECN series non-clogging, self-priming centrifugal pumps are new generation uniquely designed product suitable for varied waste water pumping applications. 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 bearings to ensure long life. The special features like removable front cover & removable rotating back assembly facilitates to limit pump’s break down time. The casing and impeller are designed for a better solid handling capacity and keeps the pump clog free. These pumps are used for special applications such as municipal sewage and industrial dewatering system.
