Basics of Mini Pump
A mixture of water air is used to reach a state of the fully primed pump. A low-pressure zone at the center is created, when the impeller located inside the casing rotates. The pressure difference inside the casing and the outside air causes a suction effect that results in water moving up the suction pipe. The self-priming pump mixes the air with recirculating water, all the air in the suction pipe is displaced and the water is discharged.
Features of CRI Mini Pumps
CRI Self priming mini monoblock pumps are power driven by totally enclosed fan cooled AC induction two pole motor, suitable for continuous duty. Motor stator is made of low watt loss silicon laminations assembled under pressure and rigidly locked in the frame. The windings are of high grade enameled copper wire and are varnish impregnated. Construction of motor frames and usage of quality materials result in high performance, noise free operation and low temperature rise thereby increasing the life cycle of the motor. The mini pumps volute chamber and impellers are designed to give the best possible hydraulic efficiency and suction lift characteristics. Non-self priming pumps with end suction and radial delivery.
