- Unexpected changes in normal pump performance occur
- Scheduled wet-end maintenance is due
Frequently Asked Questions
Which diaphragms are available for the S20 Metallic pump?
Current S20 Metallic Design Level 1 service documentation lists Santoprene, Buna/Nitrile, FKM, EPDM, Neoprene, PTFE Overlay and Synthesis™ One-Piece PTFE diaphragms.
Is 286.020.604 a complete PTFE diaphragm assembly?
No. Part number 286.020.604 is the PTFE overlay diaphragm component. The applicable backup diaphragm must also match the complete S20 Metallic pump configuration.
Which backup diaphragm is used with the S20 Metallic PTFE overlay?
Current Sandpiper nomenclature includes PTFE configurations using either Santoprene or Neoprene backup diaphragms. Confirm the complete pump model code before ordering.
What is Sandpiper part number 286.118.000?
Part number 286.118.000 is listed as the Synthesis™ one-piece PTFE diaphragm for the current S20 Metallic pump.
Does this diaphragm fit an S20 Non-Metallic pump?
Do not assume compatibility. Current S20 Non-Metallic pumps use a different diaphragm part-number family. Use the dedicated S20 Non-Metallic diaphragm product.
