Abstract
A submersible pumping unit having a diaphragm pumping chamber connected to one end of an elongated tube, the interior of the tube being filled with hydraulic oil and a reciprocable solid of like density, the other end of the tube being connected to an oil chamber including a reciprocable piston for developing hydraulic pressure and flow oscillations at a predetermined frequency, wherein the hydraulic pressure and flow oscillations are transferred via the tube and the solid in the tube to the diaphragm pumping chamber for pumping the liquid in which the diaphragm pumping chamber is submersed.
