Abstract

A fluid controlled pumping system includes a pumping unit disposed within a fluid cavity. The pumping unit includes a passage extending to a suction end of the pumping unit. The system also includes a pressure source coupled to the passage and operable to force a fluid outwardly from the passage proximate to the suction end of the pumping unit. The system includes a pressure sensor coupled to the passage and operable to determine a fluid pressure within the passage. The system further includes a controller coupled to the pumping unit and operable to regulate an operating parameter of the pumping unit using the fluid pressure.
