MDM |
Series 72.. |
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. |
