Sandpiper S30 3" Standard Duty AODD Pump Diaphragm for Metallic Pumps
Genuine Sandpiper replacement diaphragms for compatible S30 3-inch Metallic Standard Duty AODD pumps. Choose the required diaphragm material or PTFE overlay and match the manufacturer part number to your pump configuration before ordering.
Product Overview
The Sandpiper S30 Metallic diaphragm is a replacement wear component for compatible S30 3-inch Standard Duty air-operated double diaphragm pumps with metallic wetted construction.
Current S30 Metallic configurations include aluminium, cast iron, stainless steel, Alloy C and unpainted aluminium wetted-material codes. These describe the pump construction and should not be confused with diaphragm material.
Current manufacturer documentation lists Santoprene, Buna/Nitrile, FKM, EPDM, Neoprene and PTFE overlay diaphragm options. Select the diaphragm according to the complete pump model, design level and existing replacement part number.

- Visible diaphragm cracking, wear or chemical attack
- A diaphragm rupture is suspected
- 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 listed for the S30 Metallic pump?
Current S30 Metallic Design Level 1 documentation lists Santoprene, Buna/Nitrile, FKM, EPDM, Neoprene and a PTFE overlay diaphragm.
Is 286.098.604 a complete PTFE diaphragm assembly?
No. It is listed as the PTFE overlay diaphragm. The applicable backup diaphragm must be selected according to the complete S30 Metallic pump configuration.
Which backup diaphragm is used with the S30 PTFE overlay?
Current S30 Metallic nomenclature includes PTFE configurations with either Santoprene or Neoprene backup diaphragms. Check the complete pump model code before ordering.
Does this diaphragm fit the S30 Non-Metallic pump?
Do not assume compatibility. S30 Non-Metallic pumps use a different current diaphragm part-number family. Use the dedicated S30 Non-Metallic diaphragm product instead.
How do I select the correct S30 diaphragm material?
Confirm the pump model, design level, existing diaphragm configuration, pumped fluid and operating conditions. Material suitability should be checked against current Sandpiper compatibility guidance.
