摘要
A drive system for a pump comprises a first housing defining an internal pressure chamber, the internal pressure chamber configured to be filled with a working fluid, a fluid displacement member at least partially bounding the internal pressure chamber, and a reciprocating member disposed within the internal pressure chamber, wherein the reciprocating member is configured to pull the fluid displacement member through a suction stroke and the working fluid is configured to push the fluid displacement member through a pumping stroke, the reciprocating member movable relative to the fluid displacement member.
