ABSTRACT:
A linear double acting reciprocating fluid pump is disclosed with novel anchoring means to remotely secure the pump down hole in deep well applications. The multiple piston pump may be cable operated or directly driven. Using the related remote pump lock in deep well applications, the well casing can double as a discharge conduit. The pump comprises a single tubular barrel containing opposing reciprocating pistons, each piston carrying ample fluid ports with binary valves. Mechanical linkages within the pump barrel alternately reverse opposing pistons causing them to converge and diverge, thus providing a substantially steady fluid discharge and a relatively level demand on the prime mover.
