ABSTRACT
For pipe networks distributing water and requiring a prime mover, the centrifugal pump is well established. The pressure that the pump must develop is dependent upon its application.
There are essentially two types of pipe distribution in which a pump is used to transport water. Closed systems include those applications where water is recirculated around the pipe network for the purposes of transferring heat. Open systems are those in which water is circulated and at some point or at a number of points around the pipe network it is discharged to atmosphere for the ultimate purpose of consumption.
