Flexcon Industries, a member of the Swan Group, is a world leader in the design and manufacture of pre-pressurized diaphragm tanks used in water storage applications. Focusing on quality, innovation and customer service since 1989 has positioned our products at the forefront of the industry. Constructed of steel or composite materials, Flexcon tanks are known for their unique features, high quality and durability. Our list of customers includes many of the largest and most well known distributors and manufacturers in the water systems, water treatment, plumbing and heating markets

Flexcon’s modern highly automated manufacturing facility in Randolph, MA produces tanks constructed of both steel and composite/fiberglass.  At the heart of every tank is the patented Controlled Action Diaphragm (CAD2) system which permanently separates the air side of the tank from the water storage chamber.  Our sister company Tankpac, located in Taichung, Taiwan, operates a state of the art manufacturing facility making smaller single diaphragm tanks.  Following a strict quality management system, both factories are ISO 9001 certified and every tank undergoes a rigorous inspection process before being sent into the market.


From the beginning, Flexcon has focused on listening to their customers and providing them with creative product solutions and comprehensive field support.  This approach has led to industry leading innovation in product design and application.   Flexcon is committed to producing the finest pressure tanks in the world and continues to lead the way forward in the market.
