Abstract:
A pump comprising: a pump barrel for use within a well; a reciprocating plunger disposed within the pump barrel and operatively engaging a removable connector adapted to flushly secure over the top of the plunger; said connector operatively engaging a pumping unit; the connector further comprising: an inner and outer portion with an upwardly disposed tapered edge between the inner and outer portions; and one or more tubular ports extending generally diagonally from the axis of the connector and adapted to expel fluids through hydraulic pressure resulting from the reciprocating action of the plunger and wherein said ports are annularly disposed between the upwardly disposed tapered edge and the inner portion and accessing an inner cavity of the connector; the connector further comprising an axial bore adapted to allow fluids to pass through the connector and further comprising one or more upper fluid bypass ports disposed on the inner portion.
