The AZPF-12-022LRR12MB is produced by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series. Designed for hydraulic automation circuits, the pump transfers fluid by positive displacement and is suited for power steering, lift, or press drives. A standard bearing version supports typical radial and axial loads encountered in mobile equipment. Corrosion-protected surfaces limit material degradation when the unit is exposed to moisture-laden oil. The counter-clockwise rotation direction matches engines or electric motors that turn in that sense, preventing reversal of flow. A 2-bolt 82.55 mm SAE J744 flange provides a simple face mounting interface. The 15.875 mm shaft diameter aligns with common splined or keyed couplings, while a geometric displacement of 22 cm³ per revolution defines the fixed volume delivered each turn.
Intermittent system peaks are handled up to 140 bar, allowing brief load surges without damage, and continuous operation is limited by a maximum speed of 2500 rpm to keep internal heating within safe limits. The pressure outlet uses an 11/16-12 UN-2B thread with a 19 mm port depth, giving adequate thread engagement for high-pressure fittings, whereas the suction inlet employs a 7/8-14 UNF-2B thread with a 16 mm depth to reduce inlet restrictions. NBR sealing material resists swelling in standard petroleum-based hydraulic fluids and maintains sealing integrity over the temperature range typical of industrial machinery. Finally, a weight of 4.0 kg permits single-person handling during installation or replacement inside compact power packs.
