How do Centrifugal and Positive ,Displacement, Pumps Work? Nearly all pumps fall within these two categories, with centrifugal being the most common. However, positive ,displacement, pumps come in a wider variety such as gear, lobe, peristaltic, screw, and many other types of pumps. The most common type among centrifugal ,pump, is the radial flow ,pump,.

Positive Displacement Pumps types and operation
Positive Displacement Pumps types and operation

A positive ,displacement pump, is one in which a definite volume of liquid is delivered for each cycle of ,pump, operation. This volume is constant regardless of the resistance to flow offered by the system the ,pump, is in, provided the capacity of the power unit driving the ,pump, or ,pump, component strength limits are not exceeded.
