Viton Sealing Components
The V designation in the second position identifies Viton (FKM) seats and O-rings. Viton is commonly specified for applications where PTFE or Hypalon seals are not the preferred elastomer. Verify compatibility against the actual process fluid.
316 Stainless Steel Double-Ball Check Valves
The S designation identifies 316 stainless steel check-valve balls in a double-ball arrangement. This differs from the ceramic double-ball valves used in many other PULSAtron Size 4 kits.
Glass-Filled Polypropylene Head
The FPP pump head distinguishes this kit from PVC-headed PULSAtron configurations. The head material must match the original pump and be suitable for the chemical being metered.
PVS3 Versus PTS3
K4PVS3 and K4PTS3 share the same FPP head, 316 stainless steel double-ball valves and 1/2-inch OD tubing. The difference is the seal material: Viton for PVS3 and PTFE for PTS3. Match the original wet-end code before ordering.
Typical KOPkit Components
Pulsafeeder describes typical solenoid diaphragm KOPkits as including the pump head, diaphragm, check-valve assemblies and associated maintenance components. Exact contents depend on the supplied kit revision.
Maintenance Checklist
- Confirm the Size 4 head designation.
- Verify the PVS3 wet-end code.
- Check FPP, Viton and 316 stainless steel material requirements.
