Their Fluid Couplings are used in a wide variety of industries, including cement, mining, power generation, steel, and material handling. With continuous innovation and decades of expertise, the brand has set a new benchmark in fluid power transmission technology.

Understanding Fluid Couplings

A Fluid Coupling is a hydrodynamic device that transmits rotational energy through fluid motion rather than direct contact. It is composed of three main elements — the impeller, the runner, and the housing filled with a suitable fluid, usually oil. The impeller, connected to the driving shaft, accelerates the fluid, creating kinetic energy. This fluid then transfers energy to the runner, which is connected to the driven shaft, thus achieving torque transmission smoothly and efficiently.

This mechanism makes Fluid Couplings particularly effective for applications where controlled acceleration, overload protection, and vibration absorption are essential. The fluid medium absorbs and redistributes the torque, preventing sudden mechanical shocks and extending the life of connected equipment.

Key Benefits of Fluid Couplings

Rathi Couplings designs Fluid Couplings that bring multiple advantages to industrial systems. Their innovative design not only enhances machine performance but also ensures long-term reliability.

Some of the major benefits include:

  • Smooth Power Transmission: Fluid Couplings eliminate jerks during startup and load changes.

  • Overload Protection: The coupling acts as a torque limiter, safeguarding machinery from damage during overload conditions.

  • Energy Efficiency: Efficient fluid dynamics reduce power losses and optimize energy usage.

  • Reduced Maintenance: With no direct mechanical contact between input and output shafts, wear and tear are minimized.

  • Vibration Damping: Fluid Couplings effectively absorb and dampen vibrations, ensuring stable and quiet operation.

  • Extended Equipment Life: By reducing mechanical stress, they enhance the longevity of motors, conveyors, and pumps.

These advantages make Rathi Couplings Fluid Couplings an ideal choice for industries looking for performance and reliability in demanding environments.
