AZPF-11-008RRR20MB

The AZPF-11-008RRR20MB gear pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth and supplies fixed-displacement flow for hydraulic automation circuits. It delivers 8.0 cm³ of fluid per revolution, allowing predictable volume control for proportional valve groups. Mineral oil conforming to DIN 51524 is the required medium, securing fluid compatibility across standard power units. A maximum operating pressure of 280 bar lets the pump drive medium-pressure actuators without overstressing internal components. Permissible rotation speed reaches 4000 rpm so it can couple directly to high-speed electric or combustion prime movers. Installation orientation is unrestricted, simplifying placement in confined reservoirs. The housing carries an SAE J744 82-2 (A) two-bolt flange with an 82.55 mm pilot to fit common bell housings, and mounting screws engage M6 threads to clamp the unit firmly against the motor face.

Each tapped hole offers a depth of 13 mm, providing adequate bolt engagement while preventing thread stripping under vibration. An NBR elastomer is used for all dynamic seals, giving the assembly oil resistance and endurance at the stated pressure range. The primary shaft seal measures 17 × 30 × 7 mm, defining the spare part size for scheduled maintenance. Drive coupling alignment is aided by a spline tooth thickness of 2.357 mm, which matches standard involute hubs for smooth torque transfer. A minimum usable shaft length of 21.8 mm ensures full spline engagement and limits axial play. Overall mass is 3.3 kg, keeping overhung load on the prime mover within acceptable limits for compact power-unit designs.
