Dayton 22A620 Fluid End Repair Kit

This Dayton 22A620 kit restores the fluid end of compatible air-operated double-diaphragm pumps. It supplies Santoprene check balls and diaphragms plus twelve O-rings for a complete seal refresh. Maintenance teams use it to return a pump to reliable service without replacing the whole unit.

For pumps matching Grainger 22A596 and 22A601

The kit fits pumps identified by Grainger part numbers 22A596 and 22A601 and the matching manufacturer model numbers. It is not for pumps with different fluid-end configurations, different ball or diaphragm materials, or a different count of internal components. Buyers needing a kit for another pump series should verify the exact part numbers first.

Four Santoprene check balls and two diaphragms

The repair kit contains four ball-check valves and two diaphragms, both made from Santoprene for chemical compatibility. This component count and material choice determine whether the kit matches the pump's internal layout. Confirm the required quantities before ordering.

Highlights

  • Santoprene check balls resist chemical wear
  • Santoprene diaphragms maintain flexibility across cycles
  • Four check balls ensure reliable valve sealing
  • Two diaphragms restore full pump displacement

Yes, the kit uses Santoprene for both check balls and diaphragms, matching the material specified for the compatible pump models.

How can I confirm the repair is complete after installing the kit?
