The AZPF-12-016LRR12KB gear pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth and is intended for fixed-displacement hydraulic automation. It displaces 16.0 cm³ per revolution, providing a steady medium flow rate for actuators and valves. The design tolerates a maximum operating pressure of 280 bar, allowing the unit to work in high-duty industrial circuits. Counterclockwise rotation must match the driver orientation to maintain correct porting. A SAE J744 82-2 two-bolt mounting flange delivers a standardized interface, while an 82.55 mm centering diameter aligns the housing accurately. Two M6 bolt holes that are 13 mm deep secure the flange against vibration. The drive shaft uses an ANSI B92.1 9T 16/32 DP spline so it can mate with common couplings without alteration.
The pump can run at speeds up to 3000 rpm to accommodate fast electric motors without inducing cavitation. Port sealing relies on the SAE O-ring Boss system, which minimizes leakage under full load. The pressure outlet is tapped 11/16-12 UN-2B, whereas the suction inlet uses a 7/8-14 UN-2B thread to lessen inlet losses. NBR static seals and an FPM shaft seal contain hydraulic fluid and tolerate oil additives and temperature swings. The housing weighs 3.75 kg, permitting single-person handling during installation or service. Unified thread forms on both ports streamline hose selection and reduce assembly time. These threaded ports, combined with the high speed rating, help maintain flow efficiency in compact hydraulic power packs.
