AZPF-22-019RHO30KB

The AZPF-22-019RHO30KB pump is manufactured by Bosch Rexroth as part of the AZPF External High Performance Gear Pumps series. It supplies hydraulic circuits in automation by translating rotary input into a fixed volumetric flow. Each revolution moves 19 cm³ of fluid, allowing predictable actuator motion. The unit accepts power through a taper 1:8 drive shaft, which simplifies alignment with standard couplings. Clockwise rotation is specified, so installation must follow that direction to maintain correct inlet and outlet orientation. A rectangular 36.47 mm mounting flange secures the housing to machine frames with minimal deflection. Despite its robust casting, total mass remains 4.1 kg, enabling assembly without lifting equipment.

For temporary load peaks the pump can withstand 280 bar, giving designers margin for pressure spikes in fast-cycling manifolds. Shaft torque capacity reaches 160 Nm, so the mechanical interface stays within safety limits when full pressure coincides with rated speed. Below 100 bar the pump operates down to 500 rpm, supporting low flow conditions during standby phases. Fluid containment relies on an FKM seal that resists common hydraulic oils, and the primary shaft seal measures 18 × 30 × 7 mm to match standard service kits. External surfaces are galvanized and passivated, providing corrosion protection in humid production cells.
