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.
