Poolaroo Pro Tip
When replacing the shaft extension on a PacFab Hydro pump, inspect the shaft seal and impeller for wear at the same time. These components are subject to the same service interval and replacing them together avoids a repeat teardown. Always verify the part number against your pump’s original parts diagram before ordering PacFab Hydro pumps were produced in multiple configurations, and shaft dimensions can vary by model revision.
