Product Introduction
MRH-750 hydraulic motor, Geometric Displacement 740cm3/r. Rated Pressure 210bar, Rated Power 54KW.
The MRH-750 hydraulic motor is a high-pressure, high-efficiency hydraulic power unit featuring an inner-curve, multi-acting design suitable for high-pressure operating ranges. Its compact design, small size, light weight, and low inertia make it easy to install and maintain. The MRH-750 hydraulic motor offers excellent performance characteristics, including high torque, low speed, excellent response speed, and load adaptability. It utilizes high-quality bearings and seals to ensure long-term reliability and durability.
Type: Fixed‑displacement low‑speed high‑torque radial piston motor, five‑piston design, cast‑steel housing, widely used for marine winches, anchor‑handling equipment, dredger cutter drives and heavy‑duty industrial machinery.
MRH‑750: Base model
2: MRH2 reinforced heavy‑duty version (higher shaft radial load capacity)
E: Valve housing configuration
20: Mounting flange form
S: Shaft type (spline / taper / parallel‑key)
R: Port orientation (right‑hand / left‑hand)
Notes: MRH‑750 and MRH2‑750 are different; MRH2‑750 is reinforced for heavy‑shock marine duty.
‑ Heavy industry: large mixers, heavy conveyor drives, mining machinery
Independent drain line must be fitted. Case back‑pressure ≤ 3‑5 bar, otherwise shaft‑seal failure occurs.
Recommended fluid: mineral‑based hydraulic oil; system filtration ≤ 10 μm.
Common failure modes: piston seal wear, distributor block erosion, high internal leakage, torque drop.
Do not interchange components between standard MRH‑750 and reinforced MRH2‑750.
