Description
This 2.5 Horse Power Wet End with Barb Connection is engineered exclusively for Jacuzzi® Premium and Sundance® brand Hot Tub models manufactured from May 2009 forward. Compatible with pump assemblies bearing part numbers 6500-352, 6500-365, 6500-367, or 6500-363 alongside WUA400-I or WUA400-II designations.
Important: Your pump label should display both the WUA400-I or WUA400-II designation and one of these numbers: 6500-352, 6500-365, 6500-367, or 6500-363. If your pump is an Intertek-certified Jacuzzi or Sundance unit, this wet end assembly is the appropriate replacement component.
Please be aware: When upgrading to this wet end replacement, future internal component needs will require standard WUA400 parts rather than original Jacuzzi Sundance specific parts. This complete assembly was developed as a comprehensive solution since the manufacturer does not offer a complete wet end replacement option.
COMPATIBILITY WARNING: If your pump displays WUA400-I or WUA400-II WITHOUT a 6500-series part number, this wet end is NOT the correct match. Search our store inventory for standard WUA400 components instead.
Technical Note: The key distinction between this Jacuzzi/Sundance configuration and standard versions involves the mechanical seal spring placement—the spring component is positioned on the impeller's rear in this Jacuzzi/Sundance kit, whereas standard configurations place the spring on the volute.
