Frequently Asked Questions

What is a hydrodynamic coupling?

A hydrodynamic coupling, also known as a fluid coupling, transmits torque from one shaft to another using a fluid medium. It allows smooth start-up and overload protection in industrial drives.

How does a magnetic coupling work?

A permanent magnetic coupling transfers torque through a magnetic field without physical contact. This eliminates the need for seals and reduces maintenance in pumps and mixers.

Can you customize couplings for specific applications?

Yes, we offer custom engineering services to design couplings based on your torque, speed, space, and environmental requirements.

What industries use your couplings?

Our products are widely used in mining, cement, power plants, marine propulsion, chemical processing, and bulk material handling systems.
