Rexroth 0510225027 AZPF-12-004RCB20MB

The Rexroth 0510225027, model AZPF-12-004RCB20MB, is an external gear pump from Bosch Rexroth’s AZPF series. This fixed displacement pump is engineered for robust performance and reliability in a variety of hydraulic applications. It features a clockwise direction of rotation, a tapered drive shaft (1:5), and a German standard 2-hole mounting flange. Hydraulic connections are facilitated by SAE J518 split flange connections designed for standard pressure series. The pump incorporates NBR (Nitrile Butadiene Rubber) seals, making it compatible with mineral oil-based hydraulic fluids (HL, HLP). Additionally, this model includes an integrated pressure relief valve to help protect the hydraulic system.
