STF Series Hydraulic Motor (Staff)

STF has similar technical parameter and performance with STAFFA, and are proved to be an ideal replacement of it with its excellent performance and competitive price;
Main characteristics:
1. High mechanical efficiency and starting torque due to the hydrostatic balance built between the piston, con-rod and eccentric sets which reduces the friction between con-rod and eccentric sets, also reduces the side force of pistons, and increases contact pressure ratio between the ball and socket of piston;
2. Good sealing capability, less leakage due to applying hydrostatic balance shaft disributor to prevent the shaft tilted; Enables continuous woking in high pressure condition (Max. Pressure up to 29MPa);
3. Less leakage and higher volumetric efficiency due to the special seal rings;
4. Longer overall service life due to the special materials and advanced treatment process in main driving components;
5. Ideal replacement of STAFFA due to their same installation data and similar technical performance.
