WebThe displacement of a rotary gear pump is the volume displaced during one complete . revolution of the gears. It may be calculated from the physical dimensions of the gears, or it . may be determined as the volume of fluid pumped per revolution at zero differential . pressure. The unit of displacement for most Northern Pumps can be calculated and Webleakage. For positive displacement pumps the major cause of leakage is the small amount of reverse flow that occurs before a check valve closes and possibly past the check valve after it is closed. Leakage past the piston is negligible. Diaphragm operated PD pumps have no cylinder to leak past. Rotating PD pumps, such as gear pumps or
