Construction & Advantages
Low Leakage Design: High‑precision gerotor set + advanced flow distribution; commutator runs 6× faster than output shaft for minimal leakage & high volumetric efficiency.
High Torque Density: 300cc displacement delivers 873 N·m continuous torque at low speed, ideal for heavy‑duty wheel drives.
Heavy‑Duty Bearings: Double needle roller bearings handle high radial/axial loads; suited for sweepers, loaders, and rough terrain.
Reinforced Geroler Set: Inlaid‑column stator/rotor; low start pressure, smooth rotation, long life.
High Backpressure Tolerance: Premium shaft seal allows backpressure up to 8 MPa; supports series/parallel circuits.
