AZPF-22-028RQR12MB-S0040

The AZPF-22-028RQR12MB-S0040 is produced by Bosch Rexroth within the AZPF External High Performance Gear Pumps series. This pump supplies hydraulic circuits using an internal displacement of 28 cm³ per revolution, so each shaft turn delivers a predictable volume of fluid. It tolerates intermittent system pressures up to 140 bar, allowing it to run actuators that demand short-term high load. A drive shaft torque limit of 55 Nm defines the maximum mechanical input that can be applied without damaging the gear set. The 15.875 mm shaft diameter matches common couplings and simplifies integration with standard electric or combustion prime movers. For mounting, the unit follows the SAE-A two-bolt flange pattern, providing straightforward interchangeability with other pumps that share this industry footprint.

The flange pilot diameter is 82.55 mm, which centers the housing precisely in the mating bracket and minimizes misalignment. A mass of 4.0 kg keeps handling manageable while still offering a rigid body for stable operation. Port threads follow the UNF-2B SAE BOSS form and are cut to a depth of 19 mm, giving sufficient engagement length to avoid thread pullout under pressure cycling. The pressure port is tapped 1 1/16-12 UN-2B, enabling direct connection to standard high-pressure hoses, and the suction port uses the same 1 1/16-12 UN-2B size so a single hose specification can service both lines. These connection features support quick installation and reliable sealing in industrial hydraulic automation.
