Abstract
A system for moving fluids includes a pump device having a housing and at least one piston movable in the housing to displace fluids thereby causing flow. An actuator device is connected to the at least one piston for moving the piston within the housing to displace fluids as the actuator device is moved. The actuator device includes a plurality of side portions connected to one another to form a vacuum therein and movable relative to one another as the actuator device moves reciprocally between first and second positions with one of the side portions being connected to at least one piston thereby moving the at least one piston within the housing.
