AZPF-11-016RCB20MM

The AZPF-11-016RCB20MM gear pump is manufactured by Bosch Rexroth for the AZPF External High Performance Gear Pumps series and supplies pressurized fluid for hydraulic automation loops. It runs with clockwise rotation so it pairs correctly with prime movers that deliver right-hand shaft output. A fixed displacement of 16.0 cm³ per revolution gives a constant flow rate that can be calculated directly from drive speed, which simplifies circuit sizing. The housing tolerates up to 280 bar, allowing the unit to power cylinders or motors that operate in medium-pressure ranges. A tapered-key 1:5 drive shaft centers itself inside the coupling, preventing fretting under cyclic torque. The 3 × 5 mm key produced to DIN 6888 locks the hub to the shaft and transmits rotation without backlash. An M12 × 1.5 thread at the shaft end accepts a retaining nut so the coupling components stay seated during service.

An 80 mm centering pilot on the front flange positions the pump accurately against mounting brackets, maintaining shaft alignment with the driver. Rectangular flange ports present flat sealing faces that streamline the attachment of rigid tubing in compact manifolds. The unit can be spun to 3000 rpm, a limit that guides drive selection to avoid cavitation and excessive bearing load. Four mounting holes with M6 threads cut to a depth of 13 mm let technicians secure the housing firmly to adapter plates without special hardware. A mass of 3.7 kg keeps the pump light enough for single-person handling while still delivering the performance expected from a high-efficiency external gear pump.
