AZPF-12-022LQR12MB

The AZPF-12-022LQR12MB gear pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth. It supplies hydraulic flow for automation circuits in mobile or industrial equipment. The pump moves 22 cm³ of fluid per revolution, allowing consistent delivery for medium-duty systems. A counter-clockwise rotation direction matches power-train layouts where the prime mover drives the shaft from the left side. The housing uses a 2-bolt SAE J744 82-2 mounting flange, simplifying alignment to standard motor adapters, and the flange diameter measures 82.55 mm for a secure interface.

The pumping element tolerates intermittent pressures up to 140 bar, so it can handle short load peaks without damage. The 140 bar limit applies when the pump operates intermittently, which suits functions such as steering or lifting that see cyclical demand. A 17 mm shaft diameter provides adequate torsional strength while fitting common splined or keyed couplings. The unit version is supplied with standard bearings that support the gear set without extra high-load options. Overall weight is 4.0 kg, which keeps installation manageable when the pump is mounted directly on small power packs or engine bell housings.
