Dayton PP27004BG Impeller Purpose
This Dayton PP27004BG impeller is a replacement component for straight centrifugal pumps carrying the Grainger part numbers 1TMU6, 4ZA38A and 4ZA39A. It is intended for maintenance technicians and facility engineers who need to restore flow performance on compatible Dayton pump assemblies.
Installation Notes
The impeller fits directly onto the pump shaft of the listed models, so no special tooling is required beyond standard mechanical hand tools. The most common issue is debris or corrosion on the shaft keyway that prevents the new impeller from seating fully, which can cause vibration or reduced output.
Sustained Operation Behaviour
Under continuous duty the impeller maintains its hydraulic profile as long as the pumped fluid is clean and within the pump's design limits. Abrasive particles or prolonged cavitation will erode the vanes over time, gradually reducing head pressure and flow rate until the part requires replacement.

Questions about this item
How can I confirm the Dayton PP27004BG impeller is working correctly after installation?
Verify the pump achieves its rated flow and pressure, check for smooth rotation without vibration or unusual noise, and ensure no leaks appear at the seal or connections.
What comes with the Dayton PP27004BG impeller and what must be purchased separately?
The box contains only the impeller; gaskets, seals, hardware, and any required tools for your 1TMU6, 4ZA38A, or 4ZA39A pump must be bought separately.
Which Dayton impeller version matches my pump model 1TMU6, 4ZA38A, or 4ZA39A?
