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
