HMV Series End-Face Distribution Orbital Hydraulic Motor
HMV series is fixed displacement orbital motor with end-face flow distribution, interchangeable with Danfoss OMV & Eaton 8K series. It adopts integrated orbital stator-rotor pair and auto-compensating valve plate to maintain stable volumetric efficiency after wear.The motor features square 4-hole mounting flange, involute multi-spline output shaft and dual standard oil ports, with integral cast steel housing. Equipped with double taper roller bearings to bear heavy radial impact loads. It owns low starting pressure, smooth low-speed rotation without crawling, stable performance under long-term heavy load and intermittent impact conditions. Optional external brake valve, relief valve and drain port assembly, customizable multiple displacements, direct replacement for imported equivalent motors without machine modification.
