The AZ-P-F-12-016-LQR12MB SO022 pump belongs to the AZPF External High Performance Gear Pumps series and is produced by Bosch Rexroth for hydraulic automation tasks. It moves 16.0 cm³ of fluid per revolution, providing predictable flow to actuators. A parallel keyed drive shaft built to SAE J744 16-1 A allows secure torque transfer, aided by a 17 mm shaft diameter and a 4 × 20 mm DIN 6885 key. Counter-clockwise rotation meets installations requiring that direction. The housing attaches through a 2-bolt SAE J744 82-2 A mounting flange, and an 82.55 mm pilot centers the assembly to reduce vibration. Total weight is 3.7 kg, which simplifies handling during servicing.
The pump tolerates 250 bar during continuous operation and 200 bar for intermittent peaks, supporting circuits with varying load demands. NBR sealing material limits leakage when standard hydraulic oils are used. A pressure port threaded 7/8-14 UNF-2B to a depth of 16 mm provides a secure outlet connection, while the suction side uses a 1 1/16-12 UN-2B thread with a 19 mm depth to maintain adequate inlet flow. These port dimensions, along with the stated pressure limits and sealing choice, ensure reliable fluid transfer within automated hydraulic systems.
