The AZPF-12-022RRR12MB pump belongs to the AZPF External High Performance Gear Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation tasks. It is an external gear design that delivers hydraulic fluid with a geometric displacement of 22 cm³ per revolution, allowing predictable flow in fixed-displacement circuits. The unit rotates clockwise, so system designers must align inlet and outlet ports accordingly. A continuous operating pressure rating of 180 bar supports steady service in industrial power packs, while the SAE-A two-bolt mounting flange with an 82.55 mm pilot simplifies direct attachment to standard motor adapters. Fluid connections follow the SAE UNF-2B O-ring boss pattern, providing leak-tight porting without additional adapters.
Short-term load conditions are handled by an intermittent pressure limit of 210 bar and a peak pressure capability of 230 bar, permitting brief overload events without damage. The drive shaft may run up to 2500 rpm, offering flow scalability when paired with variable-speed prime movers. Torque is transferred through a 16/32 SP involute spline, measured to ANSI B92.1 and cut to a tooth thickness of 2.357 mm for consistent fit with matching couplings. The pump weighs 4.0 kg, light enough for compact manifold blocks yet robust for mobile or stationary installations.
