The AZPF-22-022RCB20MB gear pump is produced by Bosch Rexroth within the AZPF External High Performance Gear Pumps series and serves closed-loop hydraulic automation where stable flow is required. It delivers 22.5 cm³ per revolution, and its clockwise rotation aligns with standard engine PTO drives. A continuous pressure limit of 180 bar supports steady operation, while 210 bar intermittent and 230 bar peak values accommodate transient load increases. The pump can reach 2500 rpm at the intermittent pressure rating, providing high volumetric output from a small envelope. Any installation position is permitted, so designers can orient the housing to fit tight machinery compartments. A total mass of 3.8 kg keeps handling straightforward during service or replacement.

The rectangular 80 mm mounting flange offers a common face connection, and M6 mounting holes with 13 mm depth hold the unit rigidly against torsional loads. Rectangular Flange 20 porting aligns with matching manifold blocks to minimize external piping. An M12 × 1.5 retaining nut thread secures the drive shaft to couplings for reliable torque transfer. Sealing is provided by NBR elastomer components, and the shaft seal measures 17 × 30 × 7 mm to manage pressure while limiting leakage. Hydraulic fluid must be maintained at ISO 4406 cleanliness code 21/18/15 to protect the gear set from abrasion. Together these hardware and contamination control features enable fast integration and dependable performance in modular hydraulic systems.
