Compatible Repair Kit for Dayton 2ZWN9A Pump

This repair kit is designed specifically for the Dayton 2ZWN9A straight centrifugal pump. It contains a mechanical seal, impeller with lock nut, O-ring, impeller shim kit and all necessary bolts and lockwashers. Maintenance teams can restore pump sealing and impeller function with a single package.

Limited to Specified Dayton Pump Model

The components only fit the Dayton 2ZWN9A pump; they are not interchangeable with other brands or Dayton models. California Proposition 65 warnings apply because the kit contains chemicals known to cause cancer and birth defects or other reproductive harm. Buyers needing parts for different pump types must source a separate kit.

Straightforward Installation With Included Hardware

All required fasteners are supplied, including four 3/8 in lockwashers, four 3/8 in -16 x 1 in bolts and four 5/16 in -18 hex head bolts, so no extra hardware trips are needed. The gasket material is nitrile rubber, which seats easily during reassembly. The most common issue is misplacing the thin impeller shims, which can affect clearance if not reinstalled in the correct order.
