A Fluid Coupling is a hydrodynamic device used to transmit rotating mechanical power. It operates on the principle of hydraulic force transmission, utilizing a fluid, typically oil, to transfer torque from one shaft to another. This mechanism allows for smooth acceleration, load sharing, and protection against overloads in various industrial applications.
Our fluid couplings are designed for high efficiency and durability. Below are the detailed parameters in a tabular format for clarity.

How does a fluid coupling work?
A fluid coupling works by transmitting torque through a fluid. The impeller, connected to the input shaft, moves the fluid, which then strikes the blades of the turbine connected to the output shaft, causing it to rotate and transfer power smoothly without mechanical contact.
What are the main benefits of a fluid coupling?
The main benefits include smooth power transmission, protection against overloads and shocks, reduction in mechanical stress, and the ability to start heavy loads gently, which enhances the lifespan of connected equipment.
How do I select the right fluid coupling for my application?
Select based on power requirements, speed range, torque capacity, and environmental conditions. Consider factors like operating temperature, fluid type, and connection compatibility. Consulting technical datasheets and experts is recommended for optimal selection.
Can fluid couplings be used in high-temperature environments?
Yes, but it depends on the fluid and materials used. Standard models operate up to 120°C, but special designs with high-temperature fluids and seals can handle higher ranges. Always check specifications for temperature limits.
How often should the fluid be changed in a fluid coupling?
Fluid should be inspected annually and changed every 2-5 years, depending on usage intensity and operating conditions. Signs of degradation, such as discoloration or contamination, indicate the need for earlier replacement.
What maintenance is required for a fluid coupling?
Regular maintenance includes checking fluid levels, inspecting seals for leaks, monitoring operating temperatures, and ensuring proper alignment. Lubrication of external bearings may also be necessary as per manufacturer guidelines.
Are fluid couplings efficient?
Yes, modern fluid couplings offer efficiencies between 95-98% under optimal conditions. Efficiency can vary with speed and load, but they are designed to minimize energy losses compared to mechanical couplings.
Can a fluid coupling be repaired if damaged?
Yes, common repairs include replacing seals, bearings, or the fluid. Severe damage might require component replacement or professional servicing. Always follow manufacturer instructions for repairs to avoid voiding warranties.
