The AZPFF-12-008/008LCP2020KB SO007 gear pump is manufactured by Bosch Rexroth for the AZPF External High Performance Gear Pumps series. It supplies hydraulic circuits in automation systems by converting mechanical input into flow across two identical stages. The pump is configured for counter-clockwise rotation, matching power units where the prime mover turns in that direction. Section I delivers 8.0 cm³ of oil per revolution, providing moderate flow for actuators. This first section tolerates pressures up to 280 bar, allowing it to serve high-duty cylinders and motors. Fluid enters and exits Section I through a Square Flange 20 connection, which simplifies rigid pipe attachment. A 2-bolt 50 mm mounting flange aligns the housing with the drive face, while two M10 mounting bolts secure it against vibration. Continuous operation is supported up to 4000 rpm, so the unit can be coupled directly to high-speed electric motors.
The second stage moves the same 8.0 cm³ per revolution, enabling balanced parallel flows or separate circuit feeds. It also withstands 280 bar, so both sections share identical pressure limits for simplified system design. A matching Square Flange 20 on Section II keeps port hardware identical, reducing spare parts variety. An NBR housing seal combined with an FKM shaft seal contains fluid and resists mineral oil attack during extended service. Power is transmitted through a 17 mm shaft diameter sized for the rated torque. The shaft end carries an M12 × 1.5 thread that accepts standard lock nuts to hold drive couplings. A 3 × 5 mm key under DIN 6888 locates the coupling and prevents relative motion between shaft and hub. The assembly weighs 5.2 kg, allowing manual installation without lifting equipment.
