Product Description

The ROTOFLUID fluid coupling is designed to provide your plant with optimum reliability and durability. It is fitted between the motor (drive) and machine (drive component).

The ROTOFLUID fluid coupling comprises basically two impellers, with radial blades, opposed to each other, one connected to the motor shaft and the other to the input shaft of the Driven Equipment or Machine.

The ROTOFLUID fluid coupling acts like a centrifugal clutch, by driving an impeller, the oil passing from the blades to the driven part, which acts as driven impellers, transmits the power to the Equipment or Machine.

The oil, which fills the fluid coupling, transfers the torque and also lubricates moving parts.

Fluid couplings are the easiest and cheapest way of creating a perfectly Flexible Drive Train, because no mechanical parts are necessary between the motor and the Equipment or Machine being driven. Without mechanical parts, there is practically no wear.

The elasticity of the fluid coupling solves problems of power peaks in conventional electric motors and the machines they drive.


  • Easy start-up with gradual acceleration of the driven component
  • Automatic load speed adjustment on the basis of the synchronous speed of two or more motors.
  • The drive train is protected against overloads.
  • Rotational vibrations are dampened.
  • The torque transmitted complies with pre-set values.
  • Direct on-line start electric motors can be used, without star-delta starters or slip-ring motors with rheostat.

*Many versions fitted with pulleys, flexible couplings, brake drums, disc brakes, etc are available.
