  • 5 15/16 in diameter fits compatible Dayton pumps

Bronze Impeller for Dayton Pumps

This bronze impeller fits straight centrifugal pumps from Dayton and matches the 12A075A manufacturer model as well as Grainger part numbers 1TMU9 and 4ZA44A. It is a direct replacement component for maintenance teams servicing compatible pump assemblies.

Replaces Worn or Damaged Impellers

The part upgrades a degraded impeller in an existing Dayton pump when flow or pressure drops below specification. The jump is worth it when the original bronze impeller shows erosion, cavitation damage or loss of balance that affects pump efficiency.

Closed Design Limits Solids Handling

The closed impeller design suits clean liquid applications but cannot pass stringy or abrasive solids without clogging. Bronze construction resists corrosion in water service yet is not rated for aggressive chemicals that attack copper alloys.

Questions about this item

What pump models does the 5 15/16 in bronze impeller fit?

It fits Dayton straight centrifugal pumps using manufacturer model 12A075A and Grainger parts 1TMU9 and 4ZA44A.

How is the closed-design bronze impeller installed on the pump shaft?

Slide it onto the motor shaft, align the keyway with the shaft key, then secure with the supplied locknut or set screw; the step often missed is tightening the locknut to the specified torque.

When should the bronze impeller be inspected or replaced?

Inspect annually for erosion, cavitation pitting or vane distortion; replace if diameter loss exceeds 1/16 in or if vibration and flow drop noticeably.
