Description

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 heavyduty applications such as in construction machinery, presses, etc.

ADVANTAGeS

 - outstanding sliding properties

 - Stick-slip-free, no sticking (Turcon®material)

 - Tough scraper for heavy-duty operation

 - Can compensate for deflections of the piston rod or plunger

 - Very good scraping effect even against firmly adhered

dirt, etc.

 - Very good scraping effect from the inside against the

residual oil film adhering to the surface of the piston rod

 - identical installation with that of the Zurcon®excluder®500

 - Very high resistance to hydraulic media
