METHOD AND APPARATUS FOR MECHANICALLY COUPLING A MOTOR TO AN ELECTRICALLY ISOLATED PUMP

Abstract:

Provided is an electrically isolated pump system that comprises welding-type power conversion circuitry configured to convert input power to welding-type power, a motor configured to output mechanical power using motor voltage derived from the input power by a motor power conversion circuitry, and an electrically insulating isolating coupler configured to transmit the mechanical power to a pump, where the motor is electrically isolated from the pump and the pump is configured to use the transmitted mechanical power to pump fluid.
