AZPF-11-019RQR20MB

The AZPF-11-019RQR20MB gear pump is part of the AZPF External High Performance Gear Pumps series from Bosch Rexroth. It serves as the hydraulic power source in automation circuits by converting rotary motion into pressurized fluid flow. A displacement of 19 cm³ per revolution sets the volumetric output per shaft rotation, allowing designers to predict flow at a given speed. The pump can run up to 3000 rpm, a limit that defines the maximum permissible shaft rotation before cavitation or bearing stress occurs. Intermittent system loads are supported up to 170 bar, indicating the highest pressure the housing, gears, and seals can handle for short periods. The unit mounts using the SAE J744 82-2 (A) two-bolt flange, which aligns the housing to standard motor or engine adapters without additional brackets.

A shaft diameter of 15.875 mm matches common keyway couplings, transmitting torque from electric or combustion drives without slip. The flange bolt circle is 82.55 mm so matched holes on the mating face ensure concentric alignment with the drive source. Threads for the flange bolts are M6, and a thread depth of 13 mm prevents bolt bottoming while maintaining sufficient engagement for the rated pressure. The assembled pump weighs 3.9 kg, a consideration for mounting to light frames or mobile equipment where mass influences vibration and support structure selection.
