Abstract
The invention provides a pumping system which comprises a pump barrel that is adapted to be placed into a well casing; a plunger reciprocatably positioned within the pump barrel, wherein the plunger has an open top end with a sharpened edge, a bottom end, and a traveling valve at the bottom end; a connector coupled to the plunger below the top end, wherein the connector is configured to permit fluids to be moved upwardly through the connector and the plunger upon each downstroke of the plunger; and a rod coupled to the connector, wherein the rod is translatable to reciprocate the plunger within the pump barrel using an upstroke and a downstroke, and wherein the top end of the plunger is adapted to direct particulate into the plunger and away from the pump barrel upon each upstroke.
