Hello, Thomas. If the motor needs to be replaced, you will need to install the Motor 3.2kw Pmsm Vfd (350105s) PART# 5074-34 along with the PENTAIR SHAFT SEAL ASSEMBLY OEM (071734S) PART#5074-16. Click here to view the complete list of parts available for replacement on the Pentair IntelliFlo VS 3050 & VS + SVRS Models. Alternatively, if you would like to replace it with another VS+SVRS I would best recommend viewing the Hayward EcoStar Variable Speed Pump SVRS MODEL# SP3400VSPVR.
