The AZPF-11-008RCN20MB pump belongs to the AZPF External High Performance Gear Pumps series and is manufactured by Bosch Rexroth. It supplies hydraulic flow in automation circuits where consistent volumetric output is needed. The pump operates on the external gear principle, enabling straightforward construction and steady delivery. A displacement of 8 cm³ per revolution sets the flow rate for compact power units. Maximum intermittent pressure of 280 bar allows the unit to handle momentary load peaks common in machine tools. The recommended hydraulic medium is HLP mineral oil according to DIN 51524, ensuring compatibility with internal materials. Cleanliness class ISO 4406 21/18/15 must be maintained so that gear faces and bearings are not damaged by contamination. Sealing surfaces use NBR material, identified by the MB code, which resists petroleum-based fluids and maintains flexibility over standard temperature ranges.
Mechanical connection details facilitate installation in standard power packs. A shaft diameter of 17 mm mates with drive couplings, and the shaft thread of M12 × 1.5 provides a point for axial retention screws. The shaft seal measures 17 × 30 × 7 mm to prevent oil leakage along the drive end. Torque transfer to the driving motor is assisted by a key sized 3 × 5 mm in accordance with DIN 6888. The housing mounts to a motor or bracket through a 2-bolt ×50 mm flange, while two M10 bolt holes secure the pump firmly against vibration. An O-ring of 45 × 2.5 mm seats in the port face to maintain a pressure-tight connection to the manifold. Overall weight is 2.8 kg, allowing manual handling during assembly without lifting equipment.
