Pentair Large Strainer Basket | SuperFlo / SuperMax / OptiFlo Pumps | 355667Z

The Pentair Large Strainer Basket (355667Z) is the OEM replacement basket for the SuperFlo, SuperMax, and OptiFlo pump families, including variable speed models in those lines.

The strainer basket sits inside the pump's strainer housing and captures leaves, debris, and coarse particulate before water reaches the impeller. A cracked, warped, or missing basket allows debris to pass through directly to the impeller, reducing flow and accelerating wear. Replacing a damaged basket with this OEM unit restores full debris-trapping capacity and protects the pump's internal components.

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

The SuperFlo and SuperMax lines each use a large basket, but the housing dimensions and basket profile differ between pump families. Before ordering, locate the part number molded into the base or side wall of your existing basket and confirm it matches 355667Z. If your current basket is broken or unreadable, cross-reference your pump's model number against the Fits Into table above. When the strainer housing is already open for basket replacement, inspect the lid O-ring at the same time — a worn O-ring on these pumps is a common source of air leaks that reduce prime and flow performance.
