Impeller, Jacuzzi, Piranha,Thera-Max,Thera-Flo,2.5hp, Sundance Jacuzzi J Series

This 2.5HP Impeller fits a Jacuzzi Wet End only and would be found on a motor that is about 11.0 Amps on a 230V motor..... It can be found under the Name Thera-Max or Thera-Flo and is found on Jacuzzi Premium J Series Tubs and well as Sundance, I have seen these on HotSpring Tubs by Watkins and some other brands too... You need to look at the face to determine if this is your Wet End.. There are many times that the word Jacuzzi or Sundance is cast into the wet end face coming down from the Pressure Side outlet..

NOTE: See the picture of the back "Volute" in the photo section.. If your Volute has "4" Stand offs this is one of the parts that fit it.. If yours has "8" Stand offs then you need to look for your parts here..

Note: This Impeller will not look like the original but will work in the housing.. Base your choice on the amperage in this case about 11.0 Amps...

Closed face impeller made for the Piranha series spa pump by Jacuzzi. Rated at 2.5hp, it is used in a Piranha pump body, and must be installed on a 2.5hp (or greater) thru bolt motor. Also used in Thera-Max and Thera-Flo pumps.
