Replacement Impeller for 4RD16 and 5JPD9 Pumps

This Noryl impeller is a direct replacement component for Bell & Gossett pump models 4RD16 and 5JPD9. It is designed for industrial and commercial hydronic systems where the original impeller has worn or corroded. The part restores the pump’s ability to move water through heating or cooling loops. It is not intended for use in pumps with different model numbers or shaft configurations.

Straightforward Swap When Shaft and Housing Match

Installation involves removing the pump volute, sliding the old impeller off the motor shaft, and pressing the new one into place. The main difficulty arises if the motor shaft is scored, undersized, or has a different keyway than the original design, which prevents a secure fit. Corroded volute gaskets can also leak after reassembly if not replaced. No special tools are required beyond basic hand tools and a new gasket.

Noryl Construction Limits Temperature and Pressure

The impeller’s Noryl material is rated for a maximum fluid temperature of 225 degrees F and a maximum working pressure of 125 PSI. Systems operating above these limits will degrade the impeller, causing warping or cracking that reduces flow and risks pump failure. It is not suitable for steam service or high-pressure booster applications exceeding the stated ratings. Verify system conditions before fitting.

Questions about this item

How can I confirm the 189132LF impeller is operating correctly after installation?

Verify the pump delivers expected flow without vibration or noise, and ensure system pressure stays at or below the 125 PSI maximum working pressure while water temperature does not exceed 225 degrees F.

What comes with the 189132LF impeller and what must I supply separately?

The box contains only the Noryl impeller; you must provide the matching pump housing, shaft, gasket, coupling and any mounting hardware required for the 4RD16 or 5JPD9 pump.

Which version of the 189132LF impeller should I select for my pump?

Choose the single 189132LF part number; it is the direct replacement for both the 4RD16 and 5JPD9 pump models and no alternative capacities or versions are offered.
