AZPG-22-040RCB20MB

The AZPG-22-040RCB20MB gear pump from Bosch Rexroth belongs to the High Performance AZPG Gear Pumps series. It supplies hydraulic power to automation circuits that need a fixed displacement source. The external gear mechanism delivers uniform flow and simplifies maintenance. Its displacement is 40 cm³ per revolution, so each shaft turn moves a known volume for accurate actuator feed rates. The shaft is set for clockwise rotation, matching common industrial motor orientations. A permissible rotational speed up to 2800 rpm allows the pump to cover medium to high speed drives without cavitation. The housing is made of aluminum, reducing mass while resisting corrosion in standard hydraulic oils. NBR sealing is used to keep the unit compatible with mineral-based fluids and to limit leakage during continuous duty.

A front flange diameter of 105 mm gives the pump a rigid mounting face that aligns the shaft with prime movers. The square mounting flange simplifies orientation during installation on standardized frames. Fluid ports are arranged as an ISO 8434-3 rectangular flange, allowing direct connection to manifold blocks without additional adapters. When driven at rated conditions the unit can supply up to 112 liters per minute, providing sufficient flow for multiple actuators in parallel. An intermittent pressure ceiling of 280 bar lets the circuit handle short load peaks without overstressing internal gears. The pump weighs 10.4 kg, keeping overall system mass manageable while still offering the strength required for high-pressure operation.
