The New Mechanical Shaft Seal Designed By Zhong Chao Carbon


Features:


1 Chamber seal (modular design - can be combined in any order), optinal with housing and lid for screw compressors with one-part and horizontally split housing

2 Very small operation gap – low leakage

3 Dry running

4 Seal rings bear radial shaft movements

5 Compensates axial shaft movements

6 No sealing components mounted on the shaft and hence no additional shaft vibrations

7 Seal rings running contact-free – sliding faces and machine consume no additional power

8 One-piece seal ring with titanium bandage

9 Both side balanced seal ring inside chamber for short-term backpressure operation

10Seal ring axially spring-loaded – no swinging up at pressure-less machine operation


Advantages:


High reliability

Long-term operation time

Maintainability
