Technicaldata
Permitted medium temperature for diaphragms
The indicated medium temperatures apply only to media
which do not corrode or swell the diaphragm materials.
The behavior of the medium with respect to the diaphragm
may be changed by the medium temperature.
The function properties, in particular the service life of the dia-
phragm, may deteriorate if the medium temperature increases.
Diaphragm Medium
EPDM -10 – +130 °C
FKM 0 – +130 °C
PTFE -10 – +130 °C
