This part is now obsolete..

This 2HP Impeller fits a Jacuzzi/Carvin Wet End only and would be found on a motor that is about 16.0 Amps on a 115V motor or 10.0 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: This Impeller will not look like the original but will work in the housing.. Base your choice on the amperage in this case about 10.0 Amps...

Closed face impeller made for the Piranha series spa pump by Jacuzzi. Rated at 2.0hp, it is used in a Piranha pump body, and must be installed on a 2.0hp (or greater) thru bolt motor. Also used in Thera-Max and Thera-Flo pumps.
