Maintenance teams servicing Dayton 2ZWZ1A units

Facilities crews who maintain the specified Dayton pump can replace worn seals and impeller components in one operation. Shops that work on other pump models or need electrical motor parts will not find compatible items in this package.

Mechanical seal and impeller assembly included

The repair kit centres on a replacement mechanical seal and a pre-assembled impeller with lock nut, supported by an O-ring, spacer and shim kit. These components determine whether the pump regains its original sealing and flow performance after overhaul.

Questions about this item

Which Dayton pump model must I already own for the 21TG91 kit to fit?

The kit is compatible with Dayton model 2ZWZ1A, also listed as Grainger part 2ZWZ1, so you need that exact pump for the parts to match.

Can I use the 5/16 in-18 hex head bolts and lockwashers from this kit on older Dayton pump hardware?

The four 5/16 in-18 hex head bolts and four lockwashers are sized for the 2ZWZ1A pump; they will only fit older hardware that shares the same thread and bolt pattern.

After installing the impeller with lock nut and O-ring, how can I confirm the repair is working?

Reassemble the pump, restore power, and verify that water moves smoothly without leaks at the mechanical seal or spacer, indicating the new impeller and seal are seated correctly.
