- Diaphragm plates are loose or damaged
- Unexpected changes in normal pump performance occur
- Scheduled wet-end maintenance is due
Frequently Asked Questions
Which diaphragms are available for the S20 Non-Metallic pump?
Current S20 Non-Metallic Design Level 3 service documentation lists Santoprene, Buna/Nitrile, FKM, Neoprene, PTFE Overlay and One-Piece Bonded PTFE diaphragms.
Is 286.119.600 a complete PTFE diaphragm assembly?
No. Part number 286.119.600 is the PTFE overlay diaphragm component. The applicable backup diaphragm must also match the complete pump configuration.
Which backup diaphragm is used with the S20 Non-Metallic PTFE overlay?
Current S20 Non-Metallic nomenclature includes PTFE configurations with Santoprene or Neoprene backup diaphragms. Verify the complete pump model code before selecting the backup diaphragm.
What is Sandpiper part number 286.114.000?
Part number 286.114.000 is listed as the one-piece bonded PTFE diaphragm for the current S20 Non-Metallic pump.
Which wetted materials are available for S20 Non-Metallic pumps?
Current manufacturer documentation identifies PVDF, polypropylene and conductive polypropylene wetted construction options.
Does this diaphragm fit an S20 Metallic pump?
Do not assume compatibility. Current S20 Metallic pumps use a different diaphragm part-number family. Use the dedicated S20 Metallic diaphragm product instead.
How do I select the correct Sandpiper S20 diaphragm?
Confirm the pump model, non-metallic construction, design level, existing diaphragm configuration, pumped fluid and operating conditions before ordering.
