This Pentair/Sta-Rite replacement is built for pump flow restoration and helps match the flow requirements of compatible 1.5 HP DuraGlas pump builds. It helps keep output and motor load aligned with the original setup, making it a practical choice when the original part is cracked, worn, leaking, stripped, brittle, or missing. It is especially useful for targeted repairs where replacing a larger pump, filter, or cleaner assembly is not necessary.Confirm the part number, model family, horsepower, size, and pre/post production notes before ordering. Small Sta-Rite and Pentair revisions can affect fit, especially on DuraGlas, DynaGlas, Cristal-Flo, GW cleaner, and DE filter systems. OEM-style fit for compatible equipment Supports dependable sealing, flow, alignment, or cleaner movement Good for rebuilds, service calls, and preventative maintenance
