Screw compressor double lip oil seals

Description Of PTFE Rotary shaft seals

PTFE Rotary Seal with one or more PTFE sealing lip(s) are designed to withstand aggressive environments, high temperatures, high pressures and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand. Many of the PTFE compounds are food grade approved.

Equipment which is required to operate with high pressures, high speeds or that requires a dry running rotary seal, can often only be accommodated by using  products where the seal lips are manufactured from the latest filled PTFE polymer technology.

Rotary Seal are often the perfect choice when the operational parameters cause premature failure of traditional sealing products.High speed lip seal applications that involve high pressures often rely upon PTFE shaft seals to deliver long term, reliable and efficient performance. Where marginal or oil free conditions exist, dry running rotary seals manufactured from advanced PTFE compounds can often present the only reliable solution. Several standard ranges of Rotary Seal are available from stock to cover peripheral speeds up to 30 m/s and pressures up to 10 Bar.

PTFE Rotary Shaft Seal is suitable for a wide range of applications, in the chemicals industry, process engineering, and general machine construction.

Typical applications: · Centrifuge machinery · Separators · Air compressors · Mixers · Agitators · Spiral conveyors · Rotary lead –through · Pumps

Advantages of PTFE Rotary Shaft Seal: ·Suitable for applications under pressurized or vacuum conditions. ·Capable of handling high peripheral speeds. ·Suitable for a temperature range of -90℃ to +250℃. ·Outstanding resistance to chemical media. ·Can be used in the food and drinks industry and in the pharmaceuticals industry. ·Good dry-running characteristics, low friction, and good resistance to wear and tear.
