0121908 Volute Casing KTH-80x (new model)

When transitioning from the old Volute Housing (0115559) to the new Volute Casing (0121908) for the KOSHIN KTH-80X trash pump, the primary part that must also be changed is the Front Cover.

According to manufacturer updates and parts compatibility records, the old and new volute designs are not independently interchangeable because their mounting points or dimensions differ slightly.

Required Part Changes

• New Front Cover (0121900): You must use the new version of the front cover to accommodate the new volute casing. The old front cover (0115545) is phased out and is only compatible with the old volute.

• O-Ring/Gaskets: While not strictly "changed" in design, it is highly recommended to replace the Volute O-Ring (0115676) and the Front Cover Packing/Gasket (0115579) during this transition to ensure a proper seal with the new housing.

Important Maintenance Tip

When you have the pump open to replace the volute, check the Impeller (0115558) for wear. If the gap between the impeller and the new volute casing is too wide, you may need to add or remove Adjusting Washers (0110081) to maintain optimal pumping efficiency.
