The ZJMS Series is a premium line of end-face flow hydraulic motors engineered for high-pressure environments and demanding industrial applications. Featuring an integrated pinion gear and high-capacity bearings, these motors are specifically designed to maintain exceptional reliability and structural integrity even when subjected to significant radial loads.
Optimized for precision and power, the ZJMS series is the ideal solution for the rotary drive systems of small excavators with a tonnage of less than 2 tons. Its versatile design allows for the seamless assembly of overflow valves and essential blocks directly onto the unit, ensuring efficient integration into complex hydraulic circuits.

The ZJMS series is specifically optimized for the rotary drive of small excavators with a tonnage of less than 2 tons, providing the necessary torque and reliability for compact machinery.
Through the use of integrated pinion gears and large capacity bearings, the ZJMS series maintains high reliability and structural stability even under severe radial loading conditions.
Yes, the ZJMS design allows overflow valves or other necessary hydraulic blocks to be assembled directly onto the motor for streamlined performance.
A drain line is required for proper operation, and the back pressure in this line should not exceed a maximum of 20 bar (290 psi).
When facing the standard rotary direction at the output shaft end, Clockwise (CW) rotation is achieved when Port A is pressurized, and Counter-Clockwise (CCW) is achieved when Port B is pressurized.
Customers can opt for the inclusion of shockless relief valves and time delay valves to ensure smoother hydraulic transitions and enhanced system protection.
