- Dual seal
- Stationary single spring
- Oil-lubricated, oil-buffered
- Spring and pins not in contact with the medium
- Highly resistant silicon carbide sliding materials
Advantages
- No flushing, no water injection or circulating unit required
- Very low heat generation at sliding faces, optimum heat dissipation due to oil buffer
- Reliable performance, long service-life, low maintenance required
- Insensitive to particles in the media, no clogging, no contamination
- Seal faces at atmospheric and product side are identical in construction
- Buffer oil supply by just a small reservoir needed
- No leakage to the atmosphere – any leakage is absorbed by the buffer oil
