Franklin FMIH-40 top check-valve weight, part number 305454023, is the top check-valve weight for the Franklin FMIH-40 hydraulic-driven water pump. It is the upper weight component, not the bottom weight, flapper valve, or complete check-valve assembly.
The FMIH-40 top and bottom weights are separate parts with different replacement numbers. Confirming the position as well as the number helps avoid ordering the wrong weight when servicing the check-valve arrangement.
| Feature | Benefit |
|---|---|
| Top-position weight | Replaces the upper weight in the FMIH-40 check-valve arrangement. |
| Cast-iron construction | ASTM A48 Class 30 material for the upper check-valve weight. |
