Gas Barrier and Containment Seals - GX-200

BRAND: Durametallic

The GX-200 is a dual pressurized gas barrier metal bellows seal utilizing APGS non-contacting seal face technology. Welded metal bellows eliminate dynamic O-ring hang-up in a compact cartridge that fits ANSI and DIN standard bore seal chamber pumps. Inert barrier gas eliminates process contamination, reduces power consumption and provides zero process emissions in hazardous services.
