Pumping system and method for pumping fluids

摘要

An apparatus for transferring fluid from a vessel includes a pump, a first conduit, and a control means in fluid communication with the pump and having open and closed positions. The first end of the conduit is in fluid communication with the vessel and a second end of the conduit is in fluid communication with an inlet of the pump. The control means alternates between the open and the closed positions, whereby a stream of fluid flows into the pump inlet from the conduit when the control means first alternates to the open position, the control means alternates to the closed position and the fluid vaporizes in the pump thereby forming a vaporized portion of the fluid, and a stream of the vaporized portion of the fluid flows out of a pump outlet when the control means alternates again to the open position.
