The chemical process engineering has a special step-by-step approach of pumps. There are two type of pumps available Dynamics and positive displacement. In dynamic there are four types screw, gear, reciprocation, progressive gravity and in positive displacement there are 2 types centrifugal and axial pumps.
Pumps must be select according to their efficiency. All the details about the pumps and there types are explained in “The mihir’s Handbook of Chemical process engineering”.
