Dayton 21TH27 Pump Repair Kit

The Dayton 21TH27 kit supplies the seals, impeller, shims and hardware needed to rebuild a straight-centrifugal pump. It is designed for maintenance teams and plant operators who service Dayton models 2ZXK4 and 2ZXK5.

Compatibility and hardware check

Verify that the pump body is a Dayton straight-centrifugal unit with manufacturer model number 2ZXK4 or 2ZXK5. Confirm the gasket material requirement matches Viton and that the included 3/8 in cap screws and lock washers suit the existing flange pattern.

Suited for scheduled rebuilds, not for other brands

This kit suits technicians performing planned overhauls on the two listed Dayton pumps. It will not fit pumps from other manufacturers or different Dayton models, so buyers needing parts for other equipment should look elsewhere.
