AZPFF-12-011/008RQR1212MB-SO04

The AZPFF-12-011/008RQR1212MB-SO04 is manufactured by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series and is used to deliver pressurized fluid for hydraulic automation. Pump section I displaces 11 cm³ per revolution, while pump section II outputs 8 cm³ per revolution; these volumes define the flow each stage can supply to actuators. The unit turns clockwise, so drive arrangements must match this rotation direction. A maximum operating pressure of 280 bar for section I allows the first stage to sustain high-pressure circuits without premature wear. The pump accepts shaft speeds up to 3500 rpm, which supports fast cycling in machines that require rapid oil delivery. A SAE-A two-bolt mounting flange with an 82.55 mm pilot centers the housing and provides a standardized interface for engine or motor adapters.

The second stage also tolerates 280 bar, giving identical pressure capability across both sections for balanced performance. A 7/8-14 UNF-2B pressure port thread mates with common SAE-ORB fittings, and an identical 7/8-14 UNF-2B thread on the suction port lets installers keep uniform hose ends on both lines. The 16 mm thread depth provides full engagement to withstand vibration and pressure spikes. A shaft diameter of 17 mm fits standard spline or keyed couplings so torque can be transmitted without custom adapters. Sealing along the drive end is handled by an NBR shaft seal sized 17 × 30 × 7 mm, preventing oil escape and keeping contaminants out of the housing.
