Pentair Volute | SuperFlo & SuperMax Variable Speed Pumps | 350089Z

The Pentair Volute (350089Z) is the OEM replacement pump housing body for the SuperFlo and SuperMax inground pump families, directing water flow from the impeller to the discharge port to maintain peak hydraulic efficiency.

The volute is the stationary housing that surrounds the impeller and converts the high-velocity water exiting the impeller into usable pressure. When the volute cracks, warps, or develops a leak at the housing seam, pump performance drops and the system loses prime. Replacing it with the correct OEM part restores the precise internal geometry the impeller was engineered to work within. Match the part number molded into your existing volute before ordering — SuperFlo and SuperMax variants are not interchangeable.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Several SuperMax VS compatibility records note "Strainer Pot, Almond" — confirming the color of the strainer housing assembly for those builds. If your pump's strainer pot is a different color, locate the part number molded directly into your existing volute and confirm it reads 350089Z before ordering. While the pump is disassembled for a volute replacement, inspect the volute O-ring and shaft seal at the same time — replacing worn seals in the same service interval avoids reopening the pump for a follow-up repair.
