“In line” diaphragm seal, with flanged connection
Diaphragm seals are designed to isolate the sensing element of pressure gauges, pressure switches and electronic pressure transmitters from process liquids which may be corrosive, viscous, sedimentous and/or with a high temperature. The diaphragm welded to the upper body and leak proof tested, ensure separation of filling fluid from process medium. Diaphragm position permit an accurate and deeper cleaning. Process sizes are ASME/UNI/DIN flanged to suit application in chemical, petrochemical, water treatment and paper industries.

Suitable to be mounted directly on pipes and for ranges from -1 bar up to 250 bar.
The seal type SEP538SM gives the possibility of locating the diaphragm seal so that it can be welded in between a pipeline from up to 1 diameter ; the type SEP538TM is suitable for a pipe of 1 up to 4″ diameter and the type SEP538LF is for fitting the diaphragm seal for pipe 1 ” up to 4″diameter.
Further more there is a type LP specially designed for low pressure from -1 up to 6 bar.

“In line” diaphragm seal
Diaphragm seals are designed to isolate the sensing element of pressure gauges and pressure switches from process fluids which may be corrosive, viscous, sedimentous and/or with a high temperature. The diaphragm is welded to the upper body, to ensure separation of filling fluid from process medium. The “in-line” diaphragm position enables deep cleaning of their surfaces. Flange clamping with metallic sealing guarantees the system against leakage at high process fluid temperatures and pressures.
