The AZPF-22-025RRR12MB-S0040 unit is manufactured by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series. Designed for hydraulic automation, it supplies pressurized fluid to cylinders and motors in machinery. A displacement of 25 cm³ per revolution establishes the output flow required for mid-range actuator sizes, while a maximum intermittent pressure of 210 bar allows the circuit to handle load spikes without damage. The pump accepts clockwise rotation so drive shafts must match this orientation. An allowable speed up to 2500 rpm broadens the selection of electric or combustion prime movers. Attachment is via an SAE J744 82-2 (A) two-bolt mounting flange, and the 82.55 mm flange diameter aligns with standard brackets in mobile equipment. The housing weighs 4.0 kg, keeping installation manageable, and NBR sealing material resists common mineral hydraulic oils under the stated pressure and temperature limits.
Fluid compatibility is further defined by a viscosity window from 12 to 800 mm²/s, ensuring adequate lubrication at start-up yet preventing excessive drag when oil thickens. The suction port tolerates absolute pressures between 0.7 and 3 bar, so tank placement must maintain these limits to avoid cavitation or seal stress. Service connections use 1 1/16-12 UN-2B threads for both suction and pressure ports, and a thread depth of 19 mm provides sufficient engagement for SAE straight-thread adapters. Torque is transmitted through a nine-tooth spline, allowing secure coupling to standard drive shafts and minimizing backlash during load reversals. Together these characteristics let the pump integrate into hydraulic circuits that demand stable inlet conditions, reliable sealing, and standardized fittings.
