Diaphragm seal model MGS9/1A


Back side diaphragm seal for high pressure, with threaded connection

Diaphragm seals are designed to isolate the sensing element of pressure gauges, pressure switches and electronic pressure transmitter from process fluids which may be corrosive, viscous, sedimentous and/or with a high temperature.
The diaphragm is mechanically clamped between the upper housing and intermediate ring and is leak proof tested to guarantee fill fluid separation from process fluid.
The model MGS9/1A0 is cleaned by removing the lower housing from the intermediate ring.
Both models are without sealing gaskets.
This construction feature and its compact design suits many application that require frequent maintenance, for model MGS9/1A0.
