Zurcon® Scraper WNV
Zurcon® Scraper WNV is a double-acting scraper. Its dynamic scraping lip is specially designed with an additional inward sealing edge to keep the residual oil film in the system. If the volume of this oil film can not be backpumped by the main rod seal, a pressure build-up between main rod seal and scraper will be prevented by lifting the scraper lip to reduce pressure. The static sealing lip and edge ensure against ingress of dirt and fluids.
