  • High reliability; easy maintenance
  • Higher mechanical and volumetric efficiency

STFC

HYDRAULIC MOTOR

STFC series’ hydraulic motor is the achievement of our year’s experience of hydrostatic balance technology. It features with higher intensity of casing and larger carrying capacity of internal dynamic components. Reduced internal friction, heat, and all negative effects are realized by hydrostatic balance technology.

PRODUCT FEATURES

  • The hydrostatic balance built between the piston, con-rod and eccentric sets reduces the friction between con-rod and eccentric sets, and also reduce the lateral friction on pistons, and contact pressure on ball the socket, thus to reduce the friction loss while on load. With above, STFC series’ motor features with high mechanical efficiency and starting torque (The Mechanical efficiency while starting is up to 90%);
  • Hydrostatic balance shaft distributor prevents the shaft from tilting, thus to get excellent sealing, less leakage, and continuous running under high pressure(Max.pressure reaches to 29Mpa);
  • Special materials and structure of seals reduce the leakage and improve the volumetric efficiency;
  • Special materials and advanced treatment on main driving parts prolong the overall service life;
  • Ideal replacement of STAFFA motor with interchangeable mounting and performance.

STFD

HYDRAULIC MOTOR

STFD series’ dual speed hydraulic motor is an upgrade of the STFC series low-speed and high torque hydraulic motors. It inherits the STFC series hydrostatic balance structure, and is features with high efficiency, high starting torque,high volumetric efficiency,etc.

STFD series’ dual speed hydraulic motor enables users to select displacement in a wide range for special working conditions. Users can switch the displacement by using a remote control or manual control,with control valve mounted on the motor.The displacement can be switched easily while the motor is running.

PRODUCT FEATURES

  • Low speed, high-torque;
  • High effciency;
  • Stable performance;
  • Wide-range option of displacement;
  • Switchable displacement while the motor is running;
  • Switch option: electromagnetic, manual, automatic.
