An energy conserving air pump includes an air operating pump section and a separate fluid pumping section capable of handling pure fluids in concentrate form or in solution, and operates by the use of a single slug of air in the air operating section to shift a shuttle valve of differential diameter incorporated therein from a first to a second positions while simultaneously allowing air to actuate reciprocating pumping members incorporated into said fluid pumping section dispensing with complicated valves of conventional air pumps and allowing an automatic cycle repetition with the same air slug from a first pump atmospheric position which permits pump priming with suction of fluids pumped therethrough to a second pump discharge position, and vice-versa.
