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. Established in 1967, NOSHOK, Inc. was one of the first companies to offer a liquid filled pressure gauge. This leading-edge feature slowly caught on as the industry began to recognize the extended service life and enhanced performance that a liquid filled pressure gauge offers. Since those early years, we’ve built on that foundation of quality and value, and grown to be an industry leader in the international marketplace, delivering Measurement Solutions to a wide variety of industries including oil & gas, fluid power, general industrial, automation, chemical processing, manufacturing, water & waste water, food & beverage, and many more.
We continue to forge ahead with our continually-expanding product offering, industry- leading warranties and forward-thinking customer support tools such as our mobile web site, one of the first of its kind in our marketplace.
