Mansfield & Green R Series diaphragm seals feature removable metal diaphragms that can be replaced or repaired if required many times over. The diaphragm is selfretained in the upper housing for easy repair or replacement. This extends the life of the seal element and allows for field replacement and service. Type R Series seals have a low operating costs and greatly reduce the need to completely replace the entire seal element, even in harsh applications.
Type R Series diaphragm seals employ a diaphragm retained between two bolted members. In the clean-out design, the diaphragm is situated between the top and middle ring. In the plain design, the diaphragm is located between the top and bottom. Type R Series diaphragms have integral gaskets with a baked-on TEFLON® finish.
A VITON O-ring also seals the fill fluid cavity. The seal element’s upper housing is contoured to allow maximum movement and minimal distortion due to improper handling. Type R seal elements have a volumetric displacement of .07 cubic inches.
