TYPE 40 FLOW-THROUGH ANNULAR STYLE REPLACEABLE DIAPHRAGM SEALS
NOSHOK FLOW-THROUGH ANNULAR STYLE REPLACEABLE DIAPHRAGM SEALS are frequently used in abrasive media applications such as slurries, heavy sludges, chemical (synthetic polymers), and diffusers (flow measurement). Process liquid flowing through the pipe exerts pressure onto a flush-mounted flexible inner cylider containing clean, captive liquid; completely isolating instrumentation from the process flow and preventing plugging. -

D74 2-PIECE INDUSTRIAL SEAL
DESCRIPTION & FEATURES
- Two piece construction and designed to withstand even the most severe process applications
- “Continuous use” seals – backing plate will prevent diaphragm from rupturing if pressure sensing instrument fails. Pressure will be held until instrument is replaced
- Diaphragm is separable for servicing and is available with a 1/4” NPT flushing connection for removing any material which may clog the process connection
- Standard diaphragm is constructed of AISI 316 stainless steel and welded to the upper chamber of the seal
- ASME B40.100 compliant
- 5 year warranty
APPLICATIONS
Where the media is low in pressure and the process fluid is corrosive or viscous and would clog instrument internals/solidify within the pressure gauge, switch or transmitter -
