The AZ-P-F-12-016-RQR12MB SO022 gear pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth. It supplies fixed displacement flow in hydraulic automation circuits such as presses or mobile machinery. The geometric displacement is 16 cm³ per revolution, delivering a precise volume of fluid each shaft turn. A maximum intermittent operating pressure of 200 bar allows the pump to handle medium-to-high pressure systems without damage. The drive shaft has a diameter of 15.875 mm and carries a 4 × 20 mm key, providing secure torque transmission to the gear set. Clockwise rotation defines the allowable drive direction and ensures correct port orientation during installation. Internal sealing is provided by NBR material, giving compatibility with common mineral oils and maintaining leak-free operation. The unit weighs 3.7 kg, so a single technician can mount it without lifting equipment.
The housing uses a 2-Bolt SAE J744 82-2 (A) mounting flange with 84 mm hole spacing, enabling direct attachment to standard pump pads. A pilot diameter of 82.55 mm centers the pump accurately on the drive source. The shaft may run at speeds up to 3000 rpm, supporting high flow rates in compact systems. The pressure port is threaded 11/16-12 UN-2B and has a depth of 19 mm, providing ample engagement for SAE adapters. The suction port thread is 7/8-14 UNF-2B with a depth of 16 mm, allowing low-restriction inlet connections. Together these standardized ports simplify hose selection and reduce installation time. Efficient high-speed service is maintained by the internal gear geometry in concert with the features described above.
