The Practical Pumping Handbook

Descripción

A pump is an item of mechanical equipment that moves liquid from one area to another by increasing the pressure of the liquid to the amount needed to overcome the combined effects of friction, gravity and system operating pressures. In spite of the wide divergence of pump types available, over 80% of all pumps used in industry are of the single stage, end suction, centrifugal pump. The centrifugal pump moves liquid by rotating one or more impellers inside a volute casing. The liquid is introduced through the casing inlet to the eye of the impeller where it is picked up by the impeller vanes. The rotation of the impeller at high speeds creates the centrifugal force that throws the liquid along the vanes, causing it to be discharged from its outside diameter at a higher velocity. This velocity energy is converted to pressure energy by the volute casing prior to discharging the liquid to the system.
