Fabric Reinforcement Diaphragm (Type -WD-08)

Fabric Reinforcement Diaphragm (Type -WD-08)

This style diaphragm is the same as the Type WD-01 in all respects expect flange mounting. The parts are molded with what equates to half of an O-ring on the flange rather than a large that surface.This O-Ring half its into a groove machined into the cylinder half of the hardware. Sealing is achieved by squeezing the bead into a properly sized groove (see table at bottom of page). The cylinder and bonnet can then be designed to make positive contact when assembled, eliminating the need for a closely controlled assembly torque. It also reduces the overall diameter of the diaphragm, reducing the hardware diameter.
