Compatible Impeller for PD-35 Pumps
The BELL AND GOSSETT 118630 is a steel impeller designed for in-line circulating pumps in the PD-35 series. It serves as a direct replacement component for hydronic heating and cooling systems that use this specific pump configuration. The part is manufactured to match the original equipment dimensions and material specification.
Check Pump Model and Series Before Ordering
Verify that the existing pump carries the Series PD-35 designation and matches the manufacturer model number 105089. Confirm the impeller diameter requirement is exactly 4.75 in and that the pump housing accepts a steel impeller. Cross-reference the Grainger part number 4RD13 if that reference appears on your current equipment documentation.
Replaces Worn Steel Impellers in PD-35 Units
This part restores proper flow when the original steel impeller has eroded, corroded or suffered mechanical damage. The upgrade is justified when pump performance drops due to impeller wear rather than seal or bearing failure. It is not suitable for pumps outside the PD-35 series or for applications requiring a different diameter or material.

Questions about this item
Does the 118630 impeller arrive as a single piece or does it include the shaft and housing?
The listing describes the 118630 impeller only; shaft, housing, gaskets and mounting hardware are not included and must be sourced separately.
How do I know the 4.75 in steel impeller fits my PD-35 pump instead of another Bell & Gossett series?
This impeller is confirmed for Series PD-35 and manufacturer model 105089; cross-reference your pump nameplate with those identifiers before ordering.
What does the 4.75 in diameter mean for flow once the impeller is installed in my circulating pump?
The 4.75 in diameter matches the original PD-35 design, so the pump will deliver the factory-rated flow and head without re-balancing or trim adjustments.
