Zurcon Excluder 500 Wiper

Excluder Wiper

The Zurcon Excluder 500 has an identical design and function as that of the Turcon Excluder 5 and is fully interchangeable with this scraper.  It is more flexible and thus easier to install, but cannot withstand such high speeds and temperatures as the Excluder 5.  The Excluder 500 is injection molded from high-grade wear-resistant polyurethane.  It is suitable as an inexpensive scraper element where large quantities are required.

The Zurcon Excluder 500 is a patented double-acting scraper with two geometrically different scraper lips which are installed back-to-back. The wiper is always installed together with an elastic O-ring in one groove.  The scraper function is performed by the Excluder 500.  The O-Ring maintains the pressure of the scraper lips against the sliding surface and can compensate any deflections of the rod.

The Excluder 500 has two functions. One, to scrape contaminants from the retracting piston rod and thus to protect the system from soiling. Two, to hold back the residual oil film on the extending piston rod on the medium side.
