ABSTRACT OF THE DISCLOSURE A pumping mechanism comprising a flat base having a central vertical post and a pair of reciprocal pumping elements mounted on the flat base and situated on either side of the central post. Each of the pumping elements comprises an upper movable assembly and a lower fixed assembly which slidably accepts the lower portion of the upper movable assembly. A driven member pivotally mounted at the midpoint of its length on the central vertical post has each end pivotably connected to each of the reciprocating pumping elements. The driven member serves to raise and lower the pumping elements in a smooth and steady fashion. A pair of collapsible piston assemblies are located within the upper movable assemblies of the reciprocal pumping elements and are collapsed and formed at the top and bottom of each stroke of the pumping elements. - 20 -
