The HCG high pressure shaft seal series orbital hydraulic motor, which boasts superior mass-to-power ratio, has been extensively used in all kinds of mobile and rotary conditions, adopting special high-pressure shaft seal design, effectively withstand high-pressure environment, wear-resistant, particularly for low flow and large torque load starting conditions.
• The optimized high-pressure combined seal design ensures excellent sealing performance and reliability. • The needle roller bearing structure makes it bear axial and radial loads better. • The unique balance plate design ensures stable operation at low speeds and
high pressures. • The full flow cooling treatment of its linkage mechanism prolongs its service life. • 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.
