The AZPF-11-011LCB20MB gear pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth and is intended to supply controlled oil flow in hydraulic automation circuits. Its displacement of 11.0 cm³ per revolution sets the volumetric output, simplifying system sizing. A maximum operating pressure of 280 bar allows the pump to power cylinders and motors in high-load machinery. The unit tolerates speeds up to 3500 rpm, permitting direct drive from fast prime movers. Counterclockwise rotation specifies shaft orientation and avoids porting errors. NBR sealing material contains mineral oil and limits leakage. A tapered 1:5 drive shaft transmits torque while easing disassembly, and the 17 mm shaft diameter provides strength without excessive mass. The shaft’s 5°42'38'' taper angle positions the hub precisely to reduce backlash.
A rectangular flange front cover with an 80 mm pilot centers the pump and resists hydraulic side loads. The identical 80 mm pilot diameter aligns the housing with motor endbells to curb vibration. Fluid ports follow the rectangular flange size 20 pattern, enabling bolt-on fittings that minimize pressure drop. Mounting holes are tapped M6, and a thread depth of 13 mm ensures secure engagement of fastening screws. The shaft end carries an M12×1.5 thread to accept pullers or retaining hardware during service. A 3×5 mm key to DIN 6888 locks the shaft to couplings and prevents slippage under peak torque. Total weight of 3.5 kg makes handling straightforward while providing thermal mass for heat dissipation.
