The AZPF-11-016LCB20MB pump belongs to the AZPF External High Performance Gear Pumps series from Bosch Rexroth and supplies pressurized fluid for hydraulic automation loops. Its geometric displacement is 16 cm³ per revolution, so every shaft turn delivers a fixed volume to cylinders or motors. Normal duty allows a maximum continuous pressure of 250 bar, while short intermittent periods can reach 280 bar without overstressing the housing. The design withstands pressure peaks up to 300 bar, protecting the pump during rapid load changes. Flow is generated with a counter-clockwise rotation direction, which must match the driving motor. These operating limits provide stable performance in medium-pressure machinery where accurate flow and robust pressure tolerance are required.
A tapered 1:5 drive shaft simplifies alignment with couplings, and the shaft end carries an M12 × 1.5 thread for a retaining nut. Torque is transmitted through a 3 × 5 mm key that follows DIN 6888. The pump mounts on a rectangular front cover flange that centers on an 80 mm pilot, and M6 mounting bolts engage 13 mm into the housing for secure attachment. Minimum absolute pressure at the suction port is 0.7 bar, so a flooded inlet prevents cavitation during high speed operation. The assembly weighs 3.7 kg, allowing manual handling during installation. These construction details ensure reliable sealing, straightforward replacement, and consistent service life in modular hydraulic manifolds.
