Abstract

A pressure-powered liquid pump is provided which includes a housing having opposite ends and configured to allow an actuator to move along a center axis. The pump also includes a first and second intake assembly, as well as a first and second discharge assembly, coupled to the actuator and respectively proximate to the opposite ends of the housing. At least one discharge conduit is coupled to the housing and extends to an atmosphere external to the liquid. The pump also has a piston configured to slide along the actuator so as to create a first chamber having a first variable pressure, and a second chamber having a second variable pressure. A method is also provided and includes the steps of submerging and maintaining the pump at an optimal depth, so as to create an inversely proportional oscillation between the first variable pressure and the second variable pressure.
