Description

Fluid Coupling

The fluid coupling is consisted of driving impeller, driven impeller, and cover. Because the power is transmitted by Fluid, being no mechanical wear, it has long life.

[Features]

- Easy installation

- Ensuring long life

- Protecting the machine against the offset and angular displacement.
