RJWDF-(P) DGS6
Mechanical Seals For Pumps
Materials
- Primary seat and seal face: Silicon carbide with DiamondFace technology
- Secondary seat and seal face: Silicon carbide with DLC coating (optional: DiamondFace technology)
- Secondary seals: FKM, FFKM, PTFE (DF-PDGS6). Other elastomers available, depending on product gas composition
- Metal parts: 1.4006 (410) and other stainless steels
Advantages
- Diamond Face sliding surface technology for maximum operational performance under multiphase process conditions (liquid, vapor, supercritical)
- Ideal upgrade solution for wet mechanical seals with dry running issues
- Simple set-up: seal gas heating and nitrogen buffer are not required
- Stiff sealing gap creates necessary heat and doesn´t require additional heating
- Significantly lower leakage rate avoids icing problems with CO2 (Joule Thomson effect) and keeps emission rate low
- High film stiffness in all operating modes
- Proven reliable and economical solution
- Adjustable to extreme narrow installation space - retrofits are easy to implement
Features
