The AZPG-22-056RDC12MB gear pump belongs to the High Performance AZPG Gear Pumps series and is produced by Bosch Rexroth for hydraulic automation circuits. It delivers a displacement of 56 cm³ per revolution to supply a predictable fluid volume. The pumping element turns clockwise, so drive orientation must match this rotation. Continuous operation is supported up to 2300 rpm, while stable suction is maintained down to 500 rpm at 25 mm²/s viscosity. Power is transmitted through a 21.806 mm major diameter spline cut to the ANSI B92.1 13T 16/32 profile. A mounting flange that follows the SAE J744 101-2 (B) two-hole pattern and a 101.6 mm pilot center the housing during installation.
The housing tolerates intermittent line pressures of 195 bar and can absorb short surges to 250 bar, letting actuators accelerate without component failure. A shaft torque limit of 300 Nm keeps mechanical stress within the drive interface. The end cover is supplied without a valve, giving system designers freedom to select external control blocks. NBR seals provide compatibility with common mineral oils and maintain sealing integrity during temperature swings. These structural allowances permit the gear pump to deliver steady flow in automated presses, machine tools, and similar hydraulic installations. By aligning mechanical, pressure, and sealing characteristics, the AZPG-22-056RDC12MB supports high-performance operation throughout the duty cycle.
