Consisting of housing (, mounting flange (2, drive shaft (, bearing blocks (, sleeve bearings (, and hydrostatic compensation plates (6. G2 series gear pumps are designed to handle the rigors of industrial use. otation of the gears creates a void at the suction inlet (7. Fluid trapped in the gear roots is transported to the pressure port (8. This merging of fluid creates flow, which reflects a pressure signal as a result of load forces. s evident by the cross-section, any void created at the suction inlet will immediately be replaced by reservoir fluid. To enhance smooth performance, a small volume of load-pressurized-fluid is needed to aid in internal lubrication Suction side 8 Pressure side 9 Driving gear (clockwise Driven gear 8 2 Symbols Single pump P Tandem pump P P S S S
