Flanged Flush Face:

Flanged Flush-Face Diaphragm Seals are useful in applications where a continuous flow of process across the diaphragm is required to prevent solids buildup and a one-piece, all-welded construction is desired.

·         One-piece Seal Design Bolts Directly to Process Flange

·         Center Instrument Exit

·         Commonly Supplied with Flush / Calibration Ring

Ideal for Gauge or Differential Pressure Transmitters

Flanged Extended Diaphragm Seal 

Extended Diaphragm Seal is ideal for highly viscous and dry powder applications. Its unique design eliminates dead space in piping. It is often used for flush mounting in thick-walled vessels and is available in standard and custom lengths

Remote Seal Assembly to Smart Transmitters

We specializes in the unique craft of assembling diaphragm seals to field transmitters for the purpose of measuring pressure, differential pressure, level, and flow.

Miniature Remote Seal

The FAHM Co. all-welded flush mini-diaphragm seal or isolation device protect pressure measuring instruments. Used to ensure process compatibility, they are also applied when process media exhibits high temperature, pulsation, and a potential for plugging or freeze-up.
