DF Flush Flanged Diaphragm Seal from Ashcroft

DF Flush Flanged Diaphragm Seal from Ashcroft
The Ashcroft® DF flush flanged diaphragm seal uses a diaphragm welded directly to the assembly flange. This eliminates much of the cost associated with bulky lower housings made from exotic and expensive wetted materials. The flush-mounted diaphragm prevents clogging and is available in a full range of metallic and coated materials.
