ABOUT BELLOFRAM

In 1950, Bellofram introduced the original rolling diaphragm for a wide variety of industries and applicatoins. The immediate, wide-spread acceptance of this successful new principal of sealing resulted in rapid company growth, and in 1957, Bellofram erected facilities in Burlington, Massachusetts.  In 1989, Bellofram moved into a new, modern facility in Newell, WV, designed, constructed and fully integrated specifically for the high-volume, high-precision manufacture of elastomeric products.  Since that time, over one billion diaphragms have been used successfully throughout the world.
