The Charly CY is a double seal available in two different configurations: double back-to-back or double in tandem. Its spring mechanism is free from contact with the pumped product, extending the life of the seal since it is most vulnerable to corrosion from chemical agents.

Its universal gland fits the majority of pumps, with ANSI Big Bore and API glands available. It is hydraulically balanced for use in Chemical, Pharmaceutical, Pulp and Paper, and Petrochemical processing.
