Manufacturers That Use the 5235210-S Pump
Several spa manufacturers have used the Balboa Water Group Vico Ultimax pump (part number 5235210-S or its alternate numbers) in their hot tubs:
Balboa Water Group: This is the manufacturer of the pump itself, and it is used in their complete spa systems.
Cal Spas: This manufacturer has used the pump and its alternate part numbers, such as 5KCP49UN9089X and PRC9089X, in some of their spas.
Master Spa: Used this pump (or similar variants) with their own internal part numbers like X320530 (2-speed) or X320529 (1-speed).
Ultrajet/Pentair: The Balboa Ultimax series was designed as a direct replacement for the discontinued Ultrajet and Ultimax series pumps, indicating past usage by manufacturers that relied on those previous pumps.
Manufacturers frequently use standard, off-the-shelf components from major suppliers like Balboa Water Group, so the pump may be found in other brands not explicitly listed in the search results.
Verifying the specific pump specifications (horsepower, voltage, amperage, frame size, and plumbing connections) is crucial for a proper match
