The AZPF-11-004LAB01MB gear pump belongs to the AZPF External High Performance Gear Pumps series produced by Bosch Rexroth for hydraulic automation circuits that require steady flow at moderate volumes. Its geometric displacement is 4.0 cm³ per revolution, providing predictable delivery for compact actuators. Counter-clockwise rotation aligns with power units where the motor is on the right side, preventing cross-porting. A parallel keyed 18 mm shaft in ISO form ensures secure torque transfer to standard electric motors, and the rectangular 80 mm flange supplies a rigid mounting face for bell-housing installation. Continuous operation is permitted up to 250 bar, while intermittent duty can reach 280 bar without excessive wear. The pump stays stable down to 600 rpm when system pressure is below 100 bar, allowing low-speed cycles, and a G 1/2 pressure port threaded to ISO 228-1 simplifies discharge line connections.
During short load spikes the pump tolerates 300 bar peaks, protecting components from cavitation and shock. Shaft torque capacity is 75 Nm, so the drive line can transmit full power without overstressing keys or bearings. A maximum speed of 4000 rpm at the P2 operating point supports high flow rates, whereas a minimum of 700 rpm at 25 mm²/s viscosity maintains lubrication when fluid temperature rises. The G 3/4 suction port reduces inlet velocity and limits noise, aiding consistent filling at elevated speeds. NBR sealing material resists mineral hydraulic oil and moderate temperatures typical of industrial machinery. Overall weight is 3.3 kg, enabling single-person handling and minimizing loads on mounting brackets.
