The NS-33 slide ring seal for plunger type GD2000P is used for applications where low friction is required. Due to its radial pressure loading arrangement, it reacts faster to pressure build up than conventional seals. The seal consists of an elastic ring of NBR, a slide ring made of abrasion-resistant PTFE-Bronze-compound which acts as the sealing ring and a lateral POM support ring. In standard materials, NBR/PTFE-Bronze/POM, the seal is suitable for use with mineral oils. For use with other fluids, contact our application engineers for guidance.
