AZPF-22-025RQR12MB-S0040

The AZPF-22-025RQR12MB-S0040 gear pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth for hydraulic automation where fixed-displacement flow is required. It turns clockwise, allowing direct coupling to right-hand prime movers. The displacement is 25 cm³ per revolution so each shaft turn sends that volume into the circuit. A maximum continuous pressure of 195 bar sustains normal machine cycles, while 225 bar can be carried for short intermittent loads without damage. Momentary pressure peaks up to 265 bar help the system absorb shock when actuators change direction. The pump can spin to 3000 rpm at rated pressure to generate high flow, and it remains stable down to 500 rpm when system pressure stays below 100 bar, supporting low-speed positioning tasks.

An SAE A two-bolt flange with an 82.55 mm pilot centers the housing and simplifies attachment to standard motor mounts. The 15.875 mm shaft diameter transfers drive torque to the internal gears while keeping deflection low. A 1 1/16-12 UN-2B thread of 19 mm is provided on the pressure port for direct connection to common high-pressure hoses, and the same thread is supplied on the suction port to unify fittings. Suction side absolute pressure may range from 0.7 to 3 bar so the inlet can run slightly above atmospheric without cavitation. These connection details ensure quick integration, and the pressure and speed capabilities outlined earlier allow the pump to support medium-pressure hydraulic circuits with predictable flow and compact size.
