AZPF-11-004RCB20MM

The AZPF-11-004RCB20MM gear pump is built by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series and supplies hydraulic flow for automation circuits where consistent volumetric output is required. A geometric displacement of 4.0 cm³ per revolution defines the volume moved each shaft turn, enabling engineers to predict actuator speed. The pump endures intermittent system peaks up to 280 bar, so it tolerates pressure spikes common in cycling machinery. A maximum speed rating of 4000 rpm allows pairing with high-speed electric or combustion prime movers without overspeed risk. Clockwise rotation aligns with right-hand mounting conventions and simplifies integration with standard power take-offs. The tapered 1:5 drive shaft forms a self-centering interface that transmits torque while easing removal during service.

The square flange front cover with an 80 mm face provides a rigid mounting surface that maintains gear alignment under load. A rectangular flange port arrangement streamlines line connection by letting hoses route flush to the housing, reducing installation depth. The 80 mm pilot diameter centers the pump precisely within the mounting flange, minimizing vibration. M6 mounting threads give uniform fastener sizing for bracket design and field replacement. NBR sealing material resists common hydraulic oils and limits leakage across the temperature range expected in plant equipment. The assembly weighs 3.2 kg, light enough for single-person handling yet substantial enough to dampen pulsation and support internal bearings.
