Pet Fountain Pump Replacement Cat Water Fountain Pump Replacement for Flower Fountain Automatic Pet Water Dispenser Replacement Pump Come with Adapter

Personally I'd stay away from 120V going directly into a water dish my pet would be interacting with. Insulation can break down over time, it may work for a decade but you won't know when it fails until your pet gets zapped. I replaced a pump in my cats water fountain last year with a 12v pump, still working great.
