The AZPFF-12-016/016LRR1212MB SO040 pump is produced by Bosch Rexroth within the AZPF External High Performance Gear Pumps series and provides dual-stage flow for hydraulic automation circuits. It turns counter-clockwise, which fixes inlet and outlet orientation in the power unit. Stage I displacement is 16.0 cm³ per revolution, and Stage II displacement is also 16.0 cm³ per revolution, bringing total displacement to 32.0 cm³ per revolution for steady delivery from both gear sets. The first stage withstands intermittent pressures up to 280 bar, while the second stage is rated for 230 bar, allowing designers to assign pressure zones appropriately. A flange conforming to SAE J744 82-2 with an 82.55 mm pilot centers the housing on the prime mover, and NBR sealing material contains the fluid under varying thermal and pressure conditions.
The unit operates with HLP hydraulic oil specified in DIN 51524, assuring compatibility with common mineral-based fluids. Continuous service is permitted when oil viscosity stays between 12 mm²/s and 800 mm²/s, so proper conditioning prevents cavitation and gear wear. Fluid temperature may range from −30 °C to +80 °C, enabling cold starts and sustained high-load running without degradation. A maximum rotational speed of 3000 rpm limits the volumetric flow rate obtainable from the stated displacement figures. The assembled pump weighs 5.2 kg, making it manageable for installation in compact power packs while retaining the mass needed for stable operation.
