A pumping system for a downhole tool positionable in a wellbore penetrating a subterranean formation. The pumping system includes an actuator, a fluid movement source and a passive flow distribution block. The actuator has a body slidably positionable in a vessel. The body defines a first chamber and a second chamber in the vessel. The fluid movement source has at least one port for selectively moving fluid in at least two directions. The passive flow distribution block is adapted to selectively divert fluid from the fluid movement source to one of the first and second chambers whereby the body is selectively reciprocated.
