THREADED FLUSH DIAPHRAGM SEAL

One‑Piece, Flush‑Face Isolation for Viscous, Slurry & Sanitary Media

Engineered for Clean, Clog‑Free Performance

The THREADED FLUSH DIAPHRAGM SEAL from AIMS Control delivers crevice‑free protection for pressure transmitters, gauges, and switches installed in lines that carry syrups, slurries, crystallising liquids, or hygienic products. A forged‑body design with a laser‑welded, flush diaphragm eliminates dead pockets where media can cake or bacteria can breed, while threaded process connections make installation simple and leak‑tight.

Durable, Safe & Built for Industrial Demands

Advantage What It Means for You
One‑Piece Forged Construction Zero gaskets = zero leak paths; resists vibration and thermal shock.
Laser‑Welded Flush Diaphragm Uniform weld bead provides long fatigue life and smooth, CIP‑friendly surface.
316L SS Wetted Parts (std.) Excellent corrosion resistance; exotic alloys available for aggressive media.
Wide Range Capability Handles 0 … 4 bar → 0 … 600 bar with full‑vacuum tolerance.
Rapid‑Response Fill Fluid Pre‑charged with Silicone DC 200 (‑40 °C … +205 °C) for fast, linear pressure transfer.
Direct or Remote Mounting Screw directly into the process or connect via capillary to isolate heat & vibration.

Typical Applications

  • Chocolate, syrup & molasses pipelines
  • Paint, resin & polymer transfer skids
  • Pulp‑and‑paper stock lines with high solids
  • Dairy & brewery fermentation vessels (CIP/SIP)
  • Waste‑water sludge handling & digestion tanks
  • Offshore chemical injection where sand or scale is present
