Dayton 21TG73 Pump Repair Kit

The Dayton 21TG73 pump repair kit is built for straight centrifugal pumps carrying the 2ZWX1 or 2ZWX2 model numbers. It supplies a Viton gasket, a mechanical seal, an O-ring, an impeller with lock nut, an impeller shim kit and the required hex head bolts and lockwashers for a complete rebuild. The kit arrives new and ready for installation on compatible Dayton equipment.

For maintenance teams servicing Dayton 2ZWX1

Technicians who need to reseal and restore those specific pump models will find every critical wear part in one package. The kit does not fit other pump brands, different Dayton model numbers or alternative pump types such as submersible or diaphragm units. Buyers working on unrelated equipment should look elsewhere for the correct components.

Viton gasket material for chemical compatibility

The gasket supplied in this kit is made from Viton, a fluoroelastomer chosen for resistance to oils, fuels and many aggressive fluids handled by straight centrifugal pumps. That material choice determines whether the repair will withstand the process media in your application. Verify that Viton suits the specific chemicals and temperatures before fitting the kit.

Questions about this item

Will the Viton gasket and mechanical seal in this kit fit the Dayton 2ZWX1 pump I already own?

Yes, the kit is listed as compatible with Dayton pump models 2ZWX1 and 2ZWX2, and includes a Viton gasket and mechanical seal for those units.

How can I confirm the repair kit is installed correctly on my 2ZWX2 pump?

After installation, the pump should operate without leaks at the seal and gasket surfaces, and the impeller should turn freely with the new lock nut and shim kit properly seated.

Does the box include all bolts and hardware needed for the 2ZWX1, or must I buy any separately?

The kit includes (2) 7/16 in -14 long hex head bolts, (3) lockwashers, (4) 3/8 in -16 x 1 in bolts, and 7/16 in -14 short hex head bolts, so no additional hardware is required.
