•Since the plunger, connecting rod, and eccentric sleeve are designed to be statically balanced, the friction between the connecting rod and the eccentric sleeve and the lateral force of the plunger body are reduced, and the contact pressure of the ball joint pair is reduced, which reduces the transmission Friction loss in the process. Therefore, the STFC series hydraulic motor has the characteristics of high mechanical efficiency and high starting torque (mechanical efficiency above 0.90 when starting);
•The shaft distributor with static pressure balance technology prevents the distributor from tilting, has good sealing performance, less leakage, and can work continuously under high pressure (maximum pressure up to 29MPa);
•The sealing ring adopts special materials and structure to reduce leakage and improve volumetric efficiency;
•The main transmission parts of the motor adopt special materials and advanced heat treatment technology to improve the overall service life;
•The appearance and installation dimensions of this series of motors are basically the same as those of the original Staffa, and the performance parameters are similar to those of the original Staffa. It is an ideal choice to replace imported Staffa motors.
