DF Flush Flanged Diaphragm Seal

Brand: Ashcroft Inc

The Ashcroft DF Flush Flanged Diaphragm Seal uses a diaphragm welded directly to the assembly flange, eliminating 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.
Features
  • Flush mounted diaphragm seal prevents clogging 
  • Engineered to minimize the use of expensive wetted materials 
  • Continuous-duty construction 
  • Available with a wide range of wetted materials
