<p>A non-metallic, diaphragm-type tank assembly (10) for use with a pressurized water system is disclosed. The tank assembly comprising a non-metallic outer body (12); a non-metallic inner shell (14), including an upper (17) and a lower (19) portion, that is contained by the non-metallic outer body; and a diaphragm (20) that is structured and arranged about the upper and lower portions of the inner shell assembly to separate said inner shell assembly into a water portion and a prssurized gas portion. Preferably, the diaphragm comprises a resilient, non-porous material and includes a bead portion (25) comprising an annular ring that is convex on an inner side and concave on an outer side at its periphery. More preferably, the bead portion (25) is removably secured to the overlapable end portion (19a) of the lower portion of the inner shell assembly by a clamping system that comprises an inner clamp hoop (22) and an outer band (24). Specifically, the outer band can be mechanically crimped to compress and secure the second overlappable end portion and the bead portion of the diaphragm between the inner clamp hoop and the outer band to provide a watertight seal for the water portion.</p> |
