A pump securable to either an electric driver motor, a power drill, or any other suitable rotary transmission means, so as to pump a liquid or a non-liquid substance. The pump is made up of generally three separate parts, namely: a core, a blade, and a chamber. The pump may be provided with a spindle. The pump may comprise of an irregular shaped offset chamber of non-circular cross section, whereas the core is mounted in the chamber for rotation about an axis offset from a center of the chamber such that one side of the core is adjacent to one side of the chamber. The pump blade is mounted in a generally vertical slot across the core such that the rotation of the core causes the blade to sweep the offset periphery wall of the chamber, the blade being slideable within the slot in the core so as to vary the amount of blade projecting outwardly form each side of the slot in accordance with the length required for engagement with the surface of the chamber. The pump further includes an inlet and an outlet for substances being pumped.
