Introducing FUSION™ integrated-plate diaphragms from Versamatic, a new kind of power for your pump. FUSION diaphragms go beyond bonding PTFE and rubber; they also meld the outer diaphragm plate into the design. This exclusive bonding process results in diaphragms that are stronger and longer-lasting than ever before. FUSION is compatible with Versamatic and Wilden® 1½-inch pumps.
