Pump seal fits standard bore chambers
GX-200 dual-pressurized gas barrier seal uses a shaft-centered cartridge design, provides zero product emissions, lowers energy costs, and eliminates seal face wear. Metal bellows design does away with dynamic O-rings and problems associated with pusher seal O-ring hangup. The seal retrofits to standard bore pump seal chambers by mounting completely outside.
