GD2000P PISTON SEAL
The 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.
