Franklin FMIH-40 impeller, part number 305455006, is the replacement impeller for the Franklin FMIH-40 hydraulic-driven water pump. The FMIH-40 uses a semi-open cast-iron impeller, and this listing is for the impeller only, not a complete pump.
Matching the replacement by the exact part number keeps impeller selection tied to the FMIH-40 pump instead of a similar-looking component from another model. Check the existing impeller configuration and the adjoining wear plate when planning service; a replacement part number does not by itself establish your system flow or pressure.

|---|---|
| Semi-open cast-iron impeller | Matches the FMIH-40 impeller design for model-specific replacement selection. |
