Frame PE piston pump provides a displacement range of 100 to 180cc/rev, designed for axial piston pumps used in hydraulic open-loop circuits. The pump incorporates a cylindrical tapered bearing to enhance load-carrying capacity, capable of sustaining pressures up to 310 bar. The junction of the pump body and end covers adopts an O-ring design, facilitating user’s accessibility for obtaining replacement parts independently. With a compact exterior design, the installation space requirement is minimized, resulting in a 10% reduction in weight compared to the P100 model.
