Description
- Dependable mechanical seal 4kd
Stationary design, balanced, multiple springs located outside the fluid handled. The large springs are insensitive to contamination and provide uniform surface pressure across the seal faces, thus ensuring a long service life. - Robust mechanical seal 4kd
Tailored to the seal installation space of the pump, suitable for fluids with high solids content. - Safe mechanical seal 4kd
In the event of a sudden drop in the barrier fluid pressure, the double pressure balanced design ensures that 4KD’s seal faces will not detach. - Compact mechanical seal 4kd
No adjusting dimensions necessary
