Diaphragm Seals Type R Series with Removable Metal Diaphragm Seal DESCRIPTION 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 Type RG 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. The fill fluid cavity is also sealed by a VITON® O-ring. 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. Removable metal diaphragm - Self-gasketing simplifies field maintenance - Extends seal service life - Low operating costs • Materials available for corrosive applications • Ideal for general purpose applications - .07 cubic inch volumetric displacement • Standard seal ratings to 2000 psig (optional to 5000 psig) • Continuous duty seal element SEAL CONFIGURATIONS Threaded Seal Elements There are four basic versions of R Series diaphragm seals with threaded attachments. The RB seal element is used for pressure applications only and has a standard pressure rating of 2500 psig (optional 5000 psig) at 100°F (38°C). The RG seal element is similar to the RB seal, except that it has a 1/4 NPT flushing connection and optional 3000 psig rating. The RA seal element has a standard pressure rating of 2500 psig at 100°F (38°C), but may also be supplied with a pressure rating of up to 5000 psig. The RH seal element is similar to the RA seal element except that it features a 1/4 NPT flushing connection and optional 3000 psig rating. Flanged Seal Elements There are three basic versions of flanged R Series seal elements. The flange is a standard raised type. The RC seal element can be supplied in 1/2” and 3/4” with Class 150 thru 1500 ANSI flange ratings. A 1” and 1-1/2” version can be supplied with a Class 150 thru 1500 ANSI rating. 2” thru 4” versions are available with Class 150 to 1500 ANSI ratings. The RD Series features a 1/4 NPT flushing connection. Type RC seal elements are also available in DIN and metric sizes. The RR Series has an exposed tantalum diaphragm and 304 stainless steel tantalum-clad bottom. Type RR Series are available in sizes from 1/2” to 3”. ANSI ratings from 150 to 1500 are available as standard. In-line Flow Thru Seal Elements In-line flow thru R Series diaphragm seals include the RJ versions for 3” and larger pipe connections. The RK versions are available with 1/4, 3/8, or 1/2 NPT process connections. The RM version is for pipe sizes from 3/4” to 3” schedule 40 pipe (other schedules available) where the diaphragm seal element is to be directly welded to the process pipe. The RN version is for pipe sizes from 3/4” to 3” requiring ANSI ratings of 150 or 300. These can be supplied with an optional TEFLON liner. The RP versions are for pipe sizes from 4” to 8” and with ANSI ratings of 150 or 300. These can be supplied with an optional TEFLON liner.
