Series ‘DS-M45’ Threaded Off-Line Mini-seal

(PDF specification)

Diaphragm Seals are designed for use in applications where chemical compatibility, trash or sludge in process or sanitary requirements prevent the use of a standard pressure gauge or gauge only installation.

            Diaphragm Seals consist mainly of an upper housing, lower housing and a separating diaphragm. These components can be selected and made of different type materials for better compatibility with the end process.

            Diaphragm seal assemblies can be made and selected with different types of pressure instruments, instrument connections, process connections or types of seals. It is important to know as much about the application as possible so that the correct specifications are used when selecting the diaphragm seal assembly.
