Abstract: A liquid transport system. The liquid transport system includes a gas displacement piping section fluidly coupled to a centrifugal pump or to other portions of the liquid transport system. The gas displacement piping section includes an inlet, and outlet and a gas discharge located between the inlet and outlet for enabling gases to escape or be displaced from the gas displacement piping section, the gas displacement piping section being configured to cause entrained gases in flowing liquid to migrate toward the gas discharge. In centrifugal pump embodiments, the gas displacement piping section may be fluidly coupled upstream or downstream of the centrifugal pump, and may include a vacuum pump and/or float valve coupled to the gas discharge.
