AZPF-10-011LHO30PB SO285

The AZPF-10-011LHO30PB SO285 pump is produced by Bosch Rexroth within the AZPF External High Performance Gear Pumps series. It supplies fixed-volume flow to hydraulic circuits used in automation, testing, and mobile machinery. The unit displaces 11 cm³ of fluid per revolution, delivering predictable output for metered actuators. It is built for counter-clockwise shaft rotation so the inlet and outlet ports align correctly with left-hand drive arrangements. A rectangular flange with a 36.47 mm pilot centers the front cover, allowing direct face mounting to standard housings. The port interface follows the Rectangular Flange 30 pattern, and threaded M8 bolts with a 13 mm engagement secure the ports against high pressure. Twelve gear teeth on each element balance flow uniformity and reduce pressure pulsation at moderate speeds. An FKM seal package marked “PB” resists mineral oil and elevated temperatures, maintaining leakage control during continuous operation.

Continuous duty pressure capability reaches 250 bar, enabling the pump to drive cylinders and motors without derating in typical industrial cycles. It accepts intermittent overloads up to 280 bar and withstands short pressure peaks to 300 bar, giving the hydraulic system tolerance for transient spikes. The drive shaft can transmit 160 Nm of torque on a 1:8 taper, matching common electric or combustion prime movers. Permissible speed extends to 3500 rpm at rated pressure P2, supporting compact power units where high rotational velocity offsets small displacement. For light-load circuits below 100 bar, the shaft may turn as slowly as 500 rpm without flow separation, while a minimum of 600 rpm is required at P2 when oil viscosity is 25 mm²/s. These speed limits define the operating envelope and help designers avoid cavitation and excessive heating under varying load conditions.
