Pump Repair Kit for Dayton Pumps

This Dayton 4YFU4 rebuild kit fits the 1DLP8, 1DLP9 and 1DLR3 models. It supplies the internal parts needed to restore pump function. The kit is intended for maintenance technicians and facility managers who service these specific units. Buyers working on other pump brands or models cannot use this kit.

Wetted Materials and Included Components

Wetted surfaces are carbon and polypropylene for chemical compatibility. The package includes an impeller, pump coupling, pump foot, motor coupling and pump housing. These parts are designed to install directly into the compatible Dayton pumps without modification. The materials determine which fluids the repaired pump can handle.

Limits of the Rebuild Approach

A rebuild kit only replaces the components listed; it does not address wear in the motor, bearings or external piping. If the motor has failed or the pump casing is cracked, this kit will not return the unit to service. Users must inspect the whole assembly before deciding whether a rebuild is sufficient.
