This invention relates to a multiphase pumping device comprising a pump suitable for pumping a pumping fluid, a recycle circuit and at splitter tank. The splitter tank is connected to an area downstream of the pump and is suitable for separating a liquid phase and a gaseous phase using pumping fluid. In addition, the recycle circuit is connected to the splitter tank and is suitable for enabling the flow of the liquid phase from the splitter tank to an area upstream of the pump.
