The AZPF-12-011RQR12MA S0022 pump is produced by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series and supplies hydraulic flow for automation loops that rely on fixed-displacement gear units. A displacement of 11 cm³ per revolution sets the flow rate, enabling accurate sizing of actuators. The unit withstands 3500 rpm so drives can reach target flow without overspeeding the prime mover. A maximum intermittent pressure of 260 bar handles short duty spikes common in lifting or clamping circuits. Clockwise rotation aligns with engines or electric motors that share the same direction, avoiding crossover couplings. A parallel keyed shaft built to SAE J744 16-1 A sends torque directly to the gears, and its 15.875 mm diameter offers sufficient strength while keeping the envelope compact. The 4 × 20 mm DIN 6885 key prevents hub slippage during load reversals. No installation-position restrictions simplify reservoir layout because the pump can be mounted horizontally or vertically without affecting performance.
An SAE J744 82-2 (A) mounting flange provides a standardized pilot face, and its 82.55 mm bolt circle centers fasteners to maintain shaft alignment while shielding bearings from side load. The housing supports flange securing or through-bolting, allowing builders to match existing bell housings or back-to-back engine plates. UN thread O-ring ports following ISO 11926-1 minimize leakage by sealing on an elastomer face instead of the thread flanks, which shortens assembly time. The pressure outlet is a 7/8-14 UNF-2B port 16 mm deep to accept high-pressure fittings, and the suction inlet uses the same size and depth so identical adapters can be stocked. NBR sealing elements tolerate common mineral oils and preserve elasticity across typical temperature swings. The pump weighs 3.6 kg, light enough for a single technician to install or replace it without lifting equipment.
