Abstract
A pumping apparatus for pumping a liquid from a source to a target includes a pump having a pump housing and a pump piston. The pump housing defines a central longitudinal bore, a transverse bore communicating with the central bore for conveying a liquid through the pump housing and a liquid reservoir communicating with the central bore and the transverse bore for retaining an amount of the liquid conveyed through the transverse bore. The pump piston is axially and rotatably slidable within the central longitudinal bore for pumping the liquid through the transverse bore.
