AZPF-22-022RSG20PB SO012

The AZPF-22-022RSG20PB SO012 pump is produced by Bosch Rexroth for the AZPF External High Performance Gear Pumps series and serves fixed-displacement hydraulic automation circuits that need steady flow delivery. A geometric displacement of 22.5 cm³ per revolution sets the volume moved each shaft turn to establish predictable pump output. The direction of rotation is clockwise, aligning the inlet and outlet ports for right-hand drive arrangements. A tapered 1:5 drive shaft facilitates secure torque transmission from the prime mover, while the 20 mm shaft end diameter matches standard coupling bores. An M14×1.5 thread on the shaft end enables locking hardware to be applied without adapters, and mounting holes accept M6 screws with 13 mm thread depth to position the housing firmly on a flange.

The unit withstands intermittent pressures up to 250 bar, allowing brief overloads without compromising structural integrity. Ambient operation between −20 °C and 110 °C is possible when fitted with the specified FKM seals, so the pump can start in cold conditions and continue running in hot engine compartments. FKM is used as the seal material to retain elasticity under oil exposure and high temperatures, maintaining a reliable barrier against leakage. An Ø80 mm Type 2 outrigger bearing supports external radial loads from belt or gear drives, keeping shaft alignment during variable duty cycles. Together, the pressure capability, temperature range, and bearing arrangement make the AZPF-22-022RSG20PB SO012 a dependable choice for compact hydraulic power modules.
