Sanitary clamp diaphragm seals

Instrumentation · Pressure

Nuova Fima MGS9/AL sanitary diaphragm seals, with quick clamp connection, isolate the sensing element of pressure gauges and pressure switches from viscous, sediment-laden or high-temperature media in the food and pharmaceutical industries. The AISI 316L diaphragm is welded to the upper body and flush with the connection, allowing thorough surface cleaning, and the clamp makes frequent removal easy during cleaning and sterilisation. They are designed to the 3-A 74-06 sanitary standard. They cover ranges from 0…1 to 0…40 bar (vacuum and compound on request) with 1" to 3" clamp connections, for 63, 100 and 150 mm gauges. Process temperature is -20 to +100 °C, with peaks up to 140 °C for 30 minutes during CIP cleaning and SIP sterilisation; the 150 °C version extends the limit to +150 °C. The connection is AISI 316 stainless steel with Ra ≤ 0.76 µm finish to ASME BPE (optionally Ra ≤ 0.51 µm or electropolished Ra ≤ 0.38 µm), and the fill fluid is FDA-approved mineral oil. At Tecnovent we help you configure the seal and gauge to suit your process line.
