The AZ-P-F-12-011-RQR12MB SO022 pump belongs to the AZPF External High Performance Gear Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits that rely on fixed-displacement flow. It delivers 11 cm³ per revolution, establishing a predictable volume for pressure generation. The unit is set for clockwise rotation, allowing direct coupling to engines or motors that follow the same direction. Torque is transferred through a parallel-keyed SAE J744 16-1 A drive shaft; this shaft is 17 mm in diameter and accepts a 4 × 20 mm key to lock the hub. Installation uses an SAE J744 82-2 (A) mounting flange, and the 82.55 mm bolt circle positions the housing precisely against mating brackets.
The pump sustains 250 bar as a continuous working pressure, handles 260 bar for intermittent duty, and endures short pressure peaks up to 300 bar without structural damage. System lines attach to an 11/16-12 UN-2B pressure port machined 19 mm deep, while fluid enters through a 7/8-14 UN-2B suction port cut 16 mm deep to minimize inlet losses. Total mass is 3.6 kg, so a single technician can position the unit during machine assembly.
