Rotary ring Worthington ERP 50 x 315 Sic

The friction pairs of the Worthington Simpson ERPI 50-315 pump cartridge seal (ERP 50 x 315, ERP 40x315) are made of materials: The material of the movable ring is Sic (silicon carbide) Single seal of the Worthington Simpson ERPI 50-315 centrifugal pump (ERP 50 x 315, ERP 40x315) - hydraulically unloaded, equipped with a floating ring on the atmospheric side. The special design of the working surface of the fixed ring with U-shaped grooves allows you to operate the seal much longer and with minimal shut-off gas consumption. Due to the flow of gas into the sealing gap, a kind of gas cushion appears, which prevents the contact of the sliding surfaces.
