Product Description

GFD radial lip seals type MW with PTFE sealing lip
Radial Lip Seals with PTFE Sealing Lip MH type.
- same design as type M
(but with an auxiliary wiper lip)

Shaft lip seals were especially developed for use under difficult and
extreme conditions.

The superior properties of PTFE as lip material combined with a corrosion resistant stainless steel housing provide the particular advantages of these rotary shaft lip seals.

Advantages and applications of MW type:
• Temperature range from -70° C to +260°C
• Lowest friction and power draw
• Long seal life because of wear resistant lip materials
• Almost universal chemical resistance (depending on lip material)
• Suitable for dry running and poorly lubricated conditions
• High shaft speed up to 36 m/s
• Exchangeable with standard lip seals according to DIN 3760
• For food or pharmaceutical industry

Housing materials:
Stainless steel (301,304)
Additional materials on request

Lip materials:
Approximately 45 lip materials are available for special applications. Following please find a selection of materials:
Material Description	Relative Wear Resistance	Temperature Range
	1 = low, 9 = high
PTFE - virgin; for food and pharmaceutical applications	3	- 230 ... +190ºC
PTFE - with Carbon and Graphite; good general properties	8	- 100 ... +225ºC
PTFE - with Graphite; good general properties	7	- 130 ... +250ºC
PTFE - with Glass fiber and Graphite; good wear resistance	9	- 100 ... +260ºC
PTFE - with special filler; good wear resistance, for unhardened stainless steel shafts	9	- 100 ... +260ºC

Technical Consultation and Service:
We will help you find the best solution for your seal problem.
Send us your drawing/sketch, working conditions (dimesions, shaft/housing material, operating speed, medium, pressure, life expectancy etc.).

All recommendations and data are based on the experience gained over decades of using those radial lip seals with PTFE sealing lip. Unknown factors and special conditions may restrict the generally valid promises. In critical cases we suggest tests with samples.
