The HF-PM45 is a swash-plate axial piston pump with pressure compensation: it delivers the flow the circuit asks for and swivels back when the setpoint is reached, saving energy and heat in machines that hold pressure more than they move. The compensator adjusts with a locking screw across the working range.
The cast housing carries a heavy-duty shaft bearing set sized for belt or coupling drive, and the mounting flange and shaft follow common industry patterns, so the pump drops into existing installations. Case drain routing keeps the housing pressure inside limits at all mounting angles.
Every pump runs on the factory stand for break-in and verification of flow, compensator setting and case leakage before dispatch.
