Product Description

BluFinCirculator Isolation Flanges (CIF) are used in pairs to connect circulating pumps in hydronic systems. These
devices rapidly isolate a circulator to be serviced and eliminate the need to drain and refill the entire system. The CIF
integrates a 2-bolt flange connection (common to small circulating pumps) with a full-port ball valve. This practical "all-in-
one" design reduces the number of plumbing connections and results in a more reliable, economical, and easily serviced
hydronic system.
