A fixed and balanced double-barrel mounting face seal can be used at higher pressures and speeds than non-balanced alternatives. It can be used with pressurized isolation solution (double seal application) or unpressurized buffer solution (series application). GMP-II seals are available in a variety of materials to meet application requirements.
