Premium Transmission Constant Speed Fluid Coupling
A Constant Speed Fluid Coupling is a robust hydrodynamic power transmission device designed to deliver smooth startup, controlled torque, and reliable overload protection in heavy industrial applications.
At AV Drive Tech, Chennai, we supply industrial-grade constant speed fluid couplings ranging from 0.5 kW to 1850 kW, engineered for conveyors, crushers, pumps, fans, mills, and other critical rotating equipment across India.
Description
What is a Constant Speed Fluid Coupling?
A Constant Speed Fluid Coupling is a mechanical power transmission device that uses fluid dynamics to transfer torque between the motor and driven equipment while maintaining near-constant output speed.
How Does It Work?
It consists of an impeller (connected to the motor) and a runner (connected to the driven machine). Power is transmitted through hydraulic fluid, reducing mechanical shock during startup and load fluctuations.
A constant speed fluid coupling transmits power smoothly from motor to driven equipment using hydraulic fluid, reducing starting shock and protecting machinery from overload.

Key Characteristics & Performance Benefits
Smooth, Jerk-Free Power Transmission
The hydrodynamic principle eliminates direct mechanical shock, protecting motors, gearboxes, and connected machinery.
Controlled Starting Torque (110% – 275%)
Adjustable starting torque ensures safe startup under loaded conditions — especially important in conveyors and crushers.
Overload Protection
In case of sudden load increase, the fluid coupling absorbs shock, preventing damage to motors and mechanical systems.
Energy Efficiency in Heavy Industries
Fluid couplings help reduce peak current during startup and minimize mechanical stress, leading to improved system efficiency.
Proven Industrial Technology
Only a limited number of manufacturers worldwide specialize in high-performance industrial fluid coupling systems, making this a specialized engineering solution.
Major Industrial Applications
Constant Speed Fluid Couplings are widely used in:
- Conveyors
