Fluid End Repair Kit for 1-inch AODD pumps

This Dayton 22A614 kit restores the fluid end of compatible air-operated double-diaphragm pumps. It fits Grainger part numbers 22A598, 34TJ44, 3HJX1 and 3HJX1A. Maintenance teams use it to return worn pumps to reliable service without replacing the entire unit. The kit contains every component needed for a complete fluid-end rebuild.

Santoprene check balls

Four Santoprene check balls and two Santoprene diaphragms resist abrasion and chemical attack during sustained operation. The ball-type valve design maintains consistent sealing through repeated pressure reversals. Twelve O-rings provide fresh sealing surfaces at every joint. The materials are chosen for long intervals between overhauls in demanding fluid-transfer applications.

Zero seals simplify reassembly and reduce leak paths

The kit includes no separate seals, relying on the O-rings and Santoprene components to seal the fluid path. Fewer parts mean faster reassembly and fewer potential leak points after the pump returns to service. Santoprene construction keeps the repair compatible with the same media the original pump handled. The package delivers a complete, drop-in refresh for the listed pump models.
