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.
