INTERNAL GEAR PUMP
Internal gear pump with radial and axial seal clearance compensation
When the gear pair in the pump rotates, it sucks pressure uid (usually hydraulic oil) into the small teeth. between the
wheel and the internal gear. The two gears mesh smoothly to ensure excellent self-priming ability. The gear cavity in the
radial direction is sealed by meshing teeth and crescent blocks. Axial upward, using axial support
The support plate forms an almost gap-free seal forming the pressure chamber. This design minimizes Volume loss is
reduced, thereby improving efciency. When the gear rotates, the tooth head enters the gear tooth. The gap between them
discharges the pressure oil.
