Diaphragm Seals Type S Series General Purpose Diaphragm Seal Elements DESCRIPTION Mansfield & Green S Series Type SM diaphragm seals feature a diaphragm which is permanently welded onto the seal element’s upper flange. This design eliminates the need for a diaphragm retaining ring and minimizes the risk of fluid leakage Type SG during normal operation or seal element maintenance. Type SB Type S Series seal elements feature an upper housing which is contoured. This design permit free movement of the diaphragm with accurate response to pressure changes. It also protects the seal element from distortion due to improper handling during maintenance routines. Type S Series diaphragm seals have a volumetric Type SJ displacement of .07 cubic inches. Filling screws are standard on all models except the high pressure Type SX Series. • Diaphragm directly welded to upper flange - Eliminates retaining ring - Minimizes risk of leaks • Ideal for general purpose application • Materials available for corrosive applications • Optional seal ratings to 10,000 psig (690 bar) • Compatible with most 4-1/2” and smaller gauges S EAL CONFIGURATIONS Threaded Seal Elements There are four basic versions of S Series diaphragm seals with threaded attachments. The SB seal element is used for pressure applications only and has a standard pressure rating of 2500 psig at 100°F (172 bar at 38°C) with an optional rating for up to 5000 psig (345 bar). The SG seal element is similar to the SB seal, except that it has a 1/4 NPT flushing connection. The SX seal element has a standard pressure rating of 10,000 psig at 100°F (690 bar at 38°C). This high pressure model can be supplied with 1/8, 1/4, 3/8, 1/2, 3/4, and 1 NPT process connections. Flanged Seal Elements There are two basic versions of flanged S Series seal elements. The flange is a standard raised type. The SC seal element can be supplied in 1/2” and 3/4”. Both sizes can be supplied for standard ANSI Class ratings of 150, 300, 600, 1500, and 2500. Type SC seals are available in ring joint, flat face and DIN sizes. The SR series features an all tantalum wetted surface. 1/2” and 3/4” sizes are available for ANSI Class 150 and 300. 1” thru 3” sizes have standard ANSI Class 150, 300, 600, and 1500 ratings. In-line Flow Thru Seal Elements In-line flow thru S Series diaphragm seals include the SJ versions for 3” and larger pipe connections. The SK versions are available with 1/4, 3/8, or 1/2 NPT process connections with a standard pressure rating of 1500 psig with an optional pressure rating of 3000 psig. The SM 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 SN 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 SP versions are for pipe sizes from 4” to 10” and with ANSI ratings of 150 or 300.
