The AZPG-22-050RAX07KB SO303 assembly belongs to the High Performance AZPG Gear Pumps series and is produced by Bosch Rexroth for fixed-displacement hydraulic circuits. It turns clockwise, matching right-hand drive layouts, and moves 50 cm³ of fluid per revolution to establish consistent flow. No installation position restrictions are imposed, so designers can mount the unit in any orientation. A parallel-keyed 25 mm shaft to ISO standards transmits motion, and the same 25 mm diameter defines the torsional interface. Operation extends to 2 600 rpm in continuous service and remains stable to 500 rpm when viscosity is 12 mm²/s and pressure stays below 100 bar. An end cover without a valve leaves space for external control elements, while NBR seals with an FKM shaft seal keep hydraulic oil contained across typical temperature ranges.
The housing tolerates 220 bar during continuous duty, 250 bar for intermittent loading, and pressure peaks of 280 bar without structural compromise. Up to 160 Nm of drive torque can be applied, matching the pressure limits with suitable mechanical strength. Installation uses M10 bolts that engage to a depth of 18 mm, providing secure clamping without over-penetration, and alignment is set by an 85 mm pilot diameter that centers the body on the mounting face. These dimensional, torque, and pressure values allow the pump to support compact power units and mobile machines that demand high load performance in a small footprint.
