FLANGED FLUSH DIAPHRAGM SEAL

Large‑Volume Isolation • Flush‑Face Hygiene • Built for 1″+ ANSI/DIN Flanges

Overview

The FLANGED FLUSH DIAPHRAGM SEAL from AIMS Control safeguards pressure transmitters, gauges, and switches where viscous, slurry, or sanitary media meet high process pressures. A spacious cavity, flush metallic diaphragm, and optional flushing ring ensure fast rinsing and zero dead pockets—making the seal equally at home in polymer reactors, crude‑oil separators, and CIP/SIP food lines. Choose AISI 316L SS or upgrade to Monel 400 / Hastelloy C‑276 for maximum corrosion resistance.

 Key Features & Benefits

Feature Advantage
Large‑Volume Chamber Improves dampening and stabilises transmitter output on pulsating lines up to 250 bar.
Flush Laser‑Welded Diaphragm Crevice‑free face prevents plugging and eases wash‑down.
Optional Flushing Ring Introduce cleaning media without dismantling the instrument.
Exotic Alloys Available Monel & Hastelloy options fight chloride stress cracking, sour gas, or strong acids.
Direct / Remote Assembly Mount the transmitter right on the flange or via capillary to isolate heat & vibration.

Typical Applications

  • Polymer & resin reactors needing on‑line CIP
  • Heavy‑crude pipelines with asphaltic deposits
  • Molten sulphur & bitumen temperature loops
  • Brewery mash tuns and wort kettles (sanitary option)
  • Offshore mud‑pump manifolds with abrasive cuttings
  • Waste‑water digesters with high solids content

Quality & Compliance

Each FLANGED FLUSH DIAPHRAGM SEAL is helium‑leak tested to 1 × 10⁻⁶ mbar‑L/s, hydro‑tested at 150 % of rating, and supplied with EN 10204 3.1 material certificates. Manufactured under ISO 9001 and PED‑compliant procedures for global acceptance.
