Diaphragm seal for pressure gauges Armaturenbau GmbH

Diaphragm Seals with Thread or with Flange Connection, Models MDM 7210, 7211 and 7280

Chemical seals models MDM 7210 and 7211 consist of three separate parts: the upper housing with welded diaphragm, the lower housing and the attachment flange.
Different materials can be combined, and different connection types and sizes. This way, our chemical seals series MDM 72.. are available in suitable variations for innumerable applications and media.
The construction and function of these models are similar, but the allowed minimum and especially the maximum pressures differ.
MDM 7280 is constructed for higher pressure (400 or 600 bar). It has no separate attachement flange as the other models, but the upper and the lower housing are tied directly together by 6 bolts M 20.
