Major Overhaul Kit - Pfeiffer Duo 65M
The vanes in this kit are made from GX material . GX is a high-strength fiberglass composite. Think of it like very tough plastic mixed with glass fibers.GX vanes are made from proven high-strength GX polymer, similar to that used by many OEM pump manufacturers . This provides a durable vane that is both thermally stable and corrosion resistant for most vacuum pump applications .
All seals in this kit are made from high-quality materials designed for vacuum service. Viton rubber offers several benefits:
Handles high heat – It stays flexible when your pump gets hot
Resists chemicals – It stands up to pump oils and harsh fluids
Lasts longer – You will not need to replace it as often
Seals tight – It stops gas and oil from leaking
