The intermittent generation of steam by a solar heat source provides a reciprocating column of water when the steam pressure acts on the top of a water column and the column in turn causes a diaphram in a chamber first to expand into an adjacent chamber when the water in the column is placed under pressure and then secondly to contract when the pressure is relieved and thereby the expanding and contracting cavity experiences a pressure which expells water from the cavity through a check valve as the cavity contracts and subsequently as the pressure is relieved the vacuum formed in the cavity as it expands draws in water through another check valve for later expulsion. The reciprocating action of the water in the column that moves the diaphram into and out of the pumping chamber is caused by alternating surges of steam in which the pressure is increased when water from a reservoir in constant fluid flow communication with a steam generating chamber is periodically caused to flow to the steam generating chamber and then impeded from flowing to the chamber. In a principal embodiment the water reservoir is elevated over the steam generating chamber and the means of providing intermittent water flow to the steam generating chamber is gravity flow controlled by a valve.

A steam driven water pump comprising: an alternating steam pressurization and vacuum production means in the form of two chambers and multiple ducting placing the chambers in fluid flow communication, one chamber being a displacement chamber capable of containing water and sustaining steam pressure and the other chamber being a heating chamber capable of transmitting heat energy to water periodically delivered to it and of sustaining steam pressure from the steam converted from the heated water, and said chambers being in fluid flow communication with each other by means of multiple ducting and valving, one duct being capable of providing steam pressure fluid flow communication between the top portions of each chamber and another duct being capable of providing periodic water flow communication through a valve from said water displacement chamber to said heating chamber to thereby provide periodic water contact with the heating chamber and consequent water conversion to steam pressurization of the chambers and, steam generator chamber heating means in the form of a thermal energy source in heat flow communication with the heating chamber and, water receiving and water impelling means by which the water in the displacement chamber can be driven from that chamber during periods of steam pressurization, and by which water can be recieved into that chamber during alternate periods of vacuum production in which periods water flow to the heating chamber is prevented, said water receiving and water impelling means being in the form of additional ducting placing the displacement chamber in fluidflow communication with a water source and reservoir and, internal water circulation means by which water is moved from the water displacement chamber to the heating chamber and, internal water circulation control means in the form of a valve capable of repeatedly, alternately providing and then preventing water fluid flow communication from the displacement chamber to the heating chamber.
