How do pumps work ?
Pumps are designed to facilitate pumping of ready mixed concrete through the pipeline under high hydraulic pressure. When ready mixed concrete is pushed through the pipeline, it is separated from pipe line wall by a lubricating layer of cement, water and fine aggregates. Ready mixed concrete should have enough cohesiveness and workability for the mix to move easily through pipeline, bends, reducers and hoses.

Pumps move fluid in a variety of ways: The accepted industry standard, as published by the Hydraulic Institute www.pumps.org, defines pumps according to the method energy is imparted to the liquid: kinetic energy pump, or positive displacement (PD) pump. Kinetic energy type – A centrifugal pump imparts energy to a liquid by means of centrifugal force produced by a rotating impeller, disk or other blade form. Centrifugal pumps are made in many shapes and sizes, and differ from one another both internally and externally to an appreciable degree. In spite of appearance, all centrifugal pumps use the same mechanical principle. Pumping action is obtained from an impeller driven by a shaft or magnetic coupling, which is connected, to a motor or some other driving device. The impeller rotates (cw or ccw direction of rotation) at a high rate of speed (usually 1725 or 3450 rpm), and the liquid being pumped flows from the eye (center) of the impeller to the outside (periphery) of the impeller by
