HDL series orbital hydraulic motor is a rotor distribution hydraulic motor with independent intellectual property rigths of Hengli, which uses a special patented end face compensation structure, which can achieve high volumetric efficiency, high starting efficiency and good load retention under high pressure conditions.
• Adoption of wheelside output for compact installation enables high throughput.
• The unique balance plate design ensures stable operation at low speeds and high pressures. • The advanced flow distribution system design greatly improves efficiency and makes the motor more compact. • A variety of flange connection sizes are provided, facilitating installation. • Optional integrated counterbalance valve design, integral design of sprocket and motor parts.
