Turcon Excluder 5
Turcon®excluder®5 is a patented double-acting scraper with scraper lip and sealing lip, positioned back-to-back. The scraper is installed with an O-ring as elastic energizing element in one groove. The scraper function is performed by the excluder®5 Turcon®element. The O-ring maintains the pressure of the scraper lips against the sliding surface and can compensate deflections of the piston rod.
Excluder®5 has two functions:
- Scrape contaminants from the retracting piston rod to protect the system from soiling
- Hold back the residual oil film on the extending piston rod on the medium side.
excluder®5 is used in conjunction with our rod seals Turcon®Stepseal®2K, Turcon®Vl Seal®or Zurcon®rimseal, i.e. seals with a hydrodynamic back-pumping function. in contrast to excluder®2, they are used particularly for heavy duty applications such as in construction machinery, presses, etc.
