The AZ-P-F-12-008-RQR12MB SO022 gear pump is part of the AZPF External High Performance Gear Pumps series from Bosch Rexroth and supplies hydraulic flow for automated machinery. Its displacement of 8 cm³ per revolution determines the volume delivered per shaft turn, while a maximum operating pressure of 260 bar allows the pump to support high-pressure circuits. A top rotation speed of 4000 rpm lets it connect to fast prime movers without overspeeding. The 15.875 mm drive shaft follows the SAE J744 16-1A standard, and a 4 × 20 mm key per DIN 6885 secures torque transfer. With a weight of 3.4 kg, the unit imposes minimal load on the mounting face and can be handled by one installer.
The mounting interface centers on an 82.55 mm pilot and matches the SAE J744 82-2 (A) flange pattern so the pump bolts directly to common motor adapters. Both inlet and outlet follow the SAE O-Ring Boss port system for leak-free operation; the pressure port uses a 7/8-14 UNF-2B thread cut to a depth of 16 mm, and the suction side mirrors that same 7/8-14 UNF-2B thread and 16 mm depth to simplify hose selection. These dimensional features align the pump with standard hydraulic hardware, ensure secure sealing, and maintain consistent flow in automated pressure and return lines.
