BCU PUMP CLASSIFICATION by Type
A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. the inlet is not walled off from the outlet like positive displacement pump, whether they are reciprocating or rotary in displacement.
Positive Displacement Pumps
Positive Displacement pump moves fluid by trapping and forcing a fixed amount of it into its discharge pipe.This kind of pump make use of its expanding cavity in the suction side to capture liquid and its decreasing cavity in the discharge side to make the liquid flows out. The liquid volume involved in each cycle of operation is constant.
