The AZPFF-12-022/016LCP2020KB SO007 is manufactured by Bosch Rexroth for the AZPF External High Performance Gear Pumps series and supplies hydraulic flow in automated machinery. It turns counter-clockwise, so a left-hand drive must be used to match the specified direction of rotation. Pump stage I delivers 22 cm³ per revolution and stage II delivers 16 cm³ per revolution, allowing two flow rates from a single housing. The drive shaft is 17 mm in diameter and follows a 1:5 tapered profile, which centers the hub and transfers torque without slip. A maximum speed of 2500 rpm keeps gear tip velocity within safe limits. The 2-bolt 50 mm mounting flange positions the pump accurately against standard power units.
Stage I can be loaded to 210 bar and stage II to 280 bar, giving designers separate pressure ranges for sequential circuits. A peak transferable drive torque of 155 Nm defines the highest load the shaft can accept before taper damage occurs. The square flange line connection with dual 20 mm ports lines up with rigid pipework and maintains port spacing. A rear cover without a valve is fitted, so external controls must handle pressure relief. The shaft end thread is M12×1.5, providing a uniform lock-nut interface for couplings. NBR gaskets seal housing joints, while an FKM shaft seal resists hot hydraulic oil at the drive interface.
