Replacement Impeller for Flexible-Impeller Pumps

The Dayton 3ACC9 is a nitrile impeller and sleeve assembly designed for self-priming flexible-impeller pumps. It suits fluid transfer, spraying, lawn and garden watering, filter systems, water drainage and equipment coolant recycling. The nitrile construction avoids metal-to-metal contact inside the pump. This component is not approved for drinking water applications.

Fits Pump Housing and Restores Priming Capability

Installation requires a compatible flexible-impeller pump housing that accepts this specific impeller profile. The assembly replaces a worn or damaged impeller to restore the pump’s self-priming action and fluid-handling performance. The pump must never be run dry, as the impeller relies on the pumped liquid for lubrication and cooling. An instruction sheet is included to guide the replacement procedure.

Instruction Sheet Guides Correct Installation

The bundled instruction sheet provides the fitting steps needed to seat the impeller and sleeve correctly in the pump housing. Proper installation ensures the nitrile vanes maintain the necessary contact pattern for reliable priming and flow. No additional tools, sealants or software are supplied with this assembly. Buyers needing a complete pump unit or a different impeller material will need to source those separately.

Questions about this item

Will the nitrile impeller degrade if the pump runs dry during a long drain job?

The instructions state the impeller must not be run in a dry condition; doing so will damage the nitrile material.

How much heat does the flexible-impeller design add to the fluid during continuous recirculation?

No metal-to-metal contact means minimal friction heating, keeping coolant temperatures stable during extended recycling runs.

Which pump models accept the 3ACC9 impeller sleeve assembly?

It fits Dayton self-priming flexible-impeller pumps that use a replaceable nitrile impeller; verify your pump’s part list for the 3ACC9 match.
