Series 1555 — plastic diaphragm seals for aggressive and ultra-pure fluids

• Body: PVC-U, PP, PVDF • Diaphragm: PTFE coated EPDM • For aggressive and ultra-pure fluids • No metal parts • OEM version The series 1555 seals suit the chemical industry, water treatment, and demineralised, reverse-osmosis or chlorinated water. For the chemical industry, water treatment, and demineralised, reverse-osmosis or chlorinated water. The seals protect pressure sensors against highly aggressive or ultra-pure fluids. Their all-engineering-plastic design, with a PTFE coated separating diaphragm, makes them very resistant. Transmission between the liquid being measured and the pressure sensing element must take place through an incompressible fluid such as oil.
