WebThe volumetric displacement of a gear pump or motor can be approximated by measurement of the internal parts and substituting the values in the following formula: V = 6.03 × w × (2d − L) × L − d 2 Where V = displacement in in³/rev w = gear width in inches d = gear tip diameter in inches ... 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
