The AZPFF-11-008/004RCB2020MB belongs to the AZPF External High Performance Gear Pumps series manufactured by Bosch Rexroth and supplies pressurized fluid for hydraulic automation circuits. It is built with two pumping sections, so it can deliver separate flow paths from a single drive shaft. Section I displaces 8.0 cm³ per revolution, while section II displaces 4.0 cm³ per revolution, a combination that supports differing actuator speeds in one system. Each section withstands up to 280 bar operating pressure to power cylinders or motors that demand high force. A maximum rotation speed of 4000 rpm enables fast cycle times without cavitation. At 5.1 kg, the pump adds minimal mass to compact power packs.
A rectangular 80 mm mounting flange aligns the housing to common IEC motor faces, and M6 mounting threads hold the unit firmly in place. The drive shaft features a 5°42'38" taper that eases coupling engagement, while an M12×1.5 shaft-nut thread locks the hub against axial movement. A shaft seal sized 17×30×7 mm made of NBR keeps oil from escaping along the shaft, and the same material is used for the 45×2.5 mm port O-ring to secure the pressure line connection. Because the pump has two discrete sections, both seals protect against cross-leakage as well as external leakage, maintaining stable circuit performance.
