Application single seal:
This seal is used in case that - due to the
nature of the product gas - no additional backup seal is required.
Through connection “A” dry, clean and filtered
gas is supplied to the seal chamber. The
resulting gas flow from the sealing
compartment prevents any dirty/wet gas
entering the seal. The primary leakage is then
discharged with the separating gas to the vent
connection “B”. The separation seal is supplied
with air or nitrogen through connection “D”.
