Why centrifugal pumps are widely used in process industries than positive displacement pumps Centrifugal pumps ate widely used in process industries. Because 1) They are simple to construct and operate 2) Installation and maintenance are easy 3) Casing can be made of up variety of materials 4) Noise free operation 5) No need of safety valve at discharge side in case of single stage centrifugal pumps 6) Can handle variety of liquids. The impeller MOC can be altered accordingly.
