This patent describes a pumping system for pumping fluid out of a well comprising a tubing string for conducting the fluid, the tubing string running down the well. It consists of a rod string fabricated of elastic material contained within the tubing string and running therealong, the rod string being spaced from the tubing string, vibration generator means for providing vibrational energy to the rod string at a frequency such as to effect resonant standing wave vibration of the rod string, and sonic impeller elements fixedly mounted on the rod string at spaced intervals. The impeller elements each have a cylindrical sleeve with an elongated cylindrical body portion with an outside diameter slightly less than the inside diameter of the tubing string to form a narrow annular gap. The annular gap fills with the fluid to form a fluid annulus. The fluid annulus presents acoustic mass impedance which provides a fluid dynamic seal against leak back flow past the body portion, the sonic energy effecting pumping action of the impeller elements to pump the well fluid up the tubing string.
