Technical Data
This diaphragm seals with flanged process connection and flush diaphragm are used to protect pressure gauges from high temperatures,
aggressive or corrosive fluids.
The flush diaphragm allows direct mounting on standardized flange
connections of pipes or tanks. With the flush diaphragm these seals
are used especially for fluids with high viscosity or a tendency to
crystallize.
Different diaphragm materials can be selected to adapt the seal to
various applications and process fluids.

Flange material
Stainless steel 1.4404 (AISI 316L)
Flange types
ASME B16.5 / EN1759-1 :
class 150 to 2500, NPS 1 1/4" to 4".
EN1092-1 :
PN 10 to 100, DN 25 to 100.
Available flange faces see table on page 3.
Other flange types on request.
Stainless steel 1.4435 (AISI 316L)
Option: Hastelloy, Uranus (see ordering details
on page 4)
The diaphragm seals can be mounted to pressure gauges or pressure
switches directly or with a flexible capillary. For use with electronic
transmitters for pressure and differential pressure the product series
D9xx is recommended.
The filling fluid of the measuring system has to be choosen compatible to the application.
