AZPFF-11-011/004LCB2020MB

The AZPFF-11-011/004LCB2020MB is a gear pump in the AZPF External High Performance Gear Pumps series produced by Bosch Rexroth for hydraulic automation tasks that require compact, double-section flow generation. The pump contains 2 sections so it can supply separate circuits or combine outputs through a single drive. The first section displaces 11 cm³ per revolution and the second section displaces 4 cm³ per revolution, allowing designers to assign a larger flow to primary actuators and a smaller flow to auxiliary functions. Both sections tolerate a maximum operating pressure of 280 bar, supporting high force operation without separate pressure classes. The shaft rotates counter-clockwise, a detail that must align with the prime mover so port orientation and lubrication paths remain correct.

The unit operates safely up to 3500 rpm, which sets the permissible speed envelope for continuous duty and influences volumetric delivery at the outlets. A rectangular 80 mm front flange locates the housing accurately against standard motor adapters and resists torsional loads during pressure peaks. The drive shaft features a 17 mm small-end diameter to match common keyed couplings used in mobile power packs. M6 mounting threads in the body let installers fasten the pump directly to a bracket or frame without additional plates, while an M12 × 1.5 retaining nut thread secures the shaft components against axial movement during start-up and load reversals.
