POSITIVE DISPLACEMENT pumps - performance AND APPLICATION. by David B. Parker Manager, R&D Testing Warren pumps Incorporated Division of IMO Industries Warren, Massachusetts PD pumps come in many designs and operating ranges, but they all work on the same principle. An increasing volume is opened to suction, filled, closed, moved to discharge, and displaced. The delivered capacity is nearly constant throughout the discharge pressure range. This constant capacity will intersect a system curve at a defined point, allowing a high degree of system control.
