Positive Displacement Pumps
Positive Displacement Pumps
A positive displacement (PD) pump moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. Its internal design protects and prevents fluid from flowing back into the pump inlet or its housing. PD pumps can be either rotary or positive displacement. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms or vanes.
