PAN CAKE DIAPHRAGM SEAL

Ultra‑Low Profile • Flush Fitment • Laser‑Welded Integrity for Harsh Process Lines

Engineered for Space‑Cramped, High‑Solids Media

The PAN CAKE DIAPHRAGM SEAL from AIMS Control is a wafer‑thin, flush‑mount barrier that protects pressure transmitters and gauges on pipelines where protrusions are unacceptable and media carry fibres, crystals, or abrasive slurries. Its disc‑style body slips between pipe flanges without adding stack height, while a laser‑welded flush diaphragm keeps product flow streamlined and clog‑free. Rated from –1 … 0 bar to 0 … 250 bar, the seal ships pre‑filled with high‑temperature Silicone DC 70 (7 °C … 371 °C) for rapid, linear pressure transmission—even during extreme thermal swings.

Durable, Flush, and Built for Industrial Performance

Feature Benefit
Ultra‑Slim “Pan Cake” Body Fits tight flange gaps; ideal for revamps where added length is impossible.
Flush, Laser‑Welded Diaphragm Crevice‑free face prevents build‑up of pulp, polymers, or crystals—easy to flush clean.
Optional Flushing Ring Introduce solvents or steam without dismantling the line—perfect for on‑the‑fly CIP.
Exotic Alloy Choices 316L SS standard; Monel 400 or Hastelloy C‑276 resist chlorides, acids, and sour gas.
Remote Capillary Assembly Mount the transmitter up to 10 m away to isolate vibration and heat.

Typical Applications

  • High‑solids stock lines in pulp‑and‑paper mills
  • Polymer melt and resin reactors requiring zero dead legs
  • Molten sulphur, asphalt, or bitumen transfer pipelines
  • Slurry service in mineral‑processing concentrators
  • Chemical reactors with rapid steam‑in/steam‑out cycles
