The AZPG-22-032RCB20MB pump belongs to the High Performance AZPG Gear Pumps series from Bosch Rexroth and supplies hydraulic fluid in automated circuits. It delivers 32 cm³ per revolution, establishing the fixed volume of oil moved through the system each cycle. Maximum continuous pressure is 250 bar, marking the allowable working load for constant duty, while the intermittent limit rises to 280 bar for short operating periods. A peak pressure of 300 bar defines the highest transient spike the housing can tolerate. Maximum rotational speed at rated conditions is 2,800 rpm, which sets the upper shaft velocity, and the minimum speed of 500 rpm at 12 mm²/s viscosity keeps flow stable at low load. There are no restrictions on the installation position, giving flexibility in mounting orientation, and the assembly weighs 10.7 kg, which affects handling and support requirements.

A 1:5 tapered drive shaft provides the primary mechanical interface, and a 5 × 7.5 mm key conforming to DIN 6888 locks the hub against torque. The shaft carries an M16 × 1.5 thread, defining the fastener used for pulley or coupling retention. A rectangular mounting flange with a 105 mm pattern forms the fixed connection to the machine frame. The pump must operate with oil cleanliness at ISO 4406 20/18/15, setting the filtration level needed to limit wear. Each of these mechanical and fluid specifications guides proper integration of the unit into hydraulic automation equipment.
