Description:

This product is a double acting scraper. The dynamic scraping lip is specially designed with an additional inwards sealing edge to keep the residual oil film in the system. If the volume of this oil film can not be back pumped by the main rod seal (e.g. u-cup) a pressure built up between u-cup and scraper will be prevented by releasing this pressure by lifting of the scraper lip. The static sealing lip and edge respectively ensure against the intrusion of dirt and fluids.
