The AZPF-11-008RHO30MB pump belongs to the AZPF External High Performance Gear Pumps series produced by Bosch Rexroth for hydraulic automation circuits where stable flow and compact build are required. It turns clockwise, so system designers must align drive shafts accordingly. The displacement is 8.0 cm³ per revolution, establishing the volume of fluid moved during each rotor cycle. A maximum rotational speed of 4000 rpm gives flexibility for variable-speed drives while keeping volumetric efficiency. Continuous operation is rated for 250 bar, allowing it to maintain pressure in closed-loop circuits. Suction inlet conditions are defined between 0.7 and 3 bar absolute, which helps prevent cavitation at the pump entry. The front cover centering diameter measures 36.47 mm, providing a tight fit on mounting brackets and reducing misalignment.
For duty cycles that exceed the nominal point, the pump tolerates 280 bar intermittently and up to 300 bar during brief peaks, enabling short pressure surges without damage. The shaft end is 16.65 mm in diameter and is threaded M12×1.5, facilitating direct coupling with standard drive hubs. Rectangular Flange 30 porting simplifies attachment to manifold blocks, and the ports are secured with M6 fasteners threaded 13 mm deep to resist loosening under vibration. NBR seals are installed to contain hydraulic fluid while tolerating common mineral oils and moderate temperature ranges. These construction details complete the mechanical interface and pressure limits necessary for integrating the pump into industrial power units.
