Abstract
A fluidic pumping system comprises a reverse flow diverter positioned below the level of a liquid to be pumped and inserted between a charge vessel and a delivery pipe. Control means including signal generating means, conveniently an ultrasonic transducer, effect alternate pressurizing and venting of the charge vessel for pumping the liquid. A pipe for the supply of compressed air to the charge vessel serves as a waveguide for the signals from the signal generating means.
