Transfer Pump D.ESPI consists of a stainless steel casting body with an internal rotor with movable vanes. These paddles are the ones that drive the oil from its admission to the exit. We can highlight among the main advantages that it is a compact pump, very light and manageable thanks to the fact that it incorporates a trolley with wheels and an inverter switch that allows a reversible flow. There is also the option of incorporating a two speed engine.
