ABSTRACT:
A profiled plunger is provided for use with a reciprocating pump. A flushing chamber and a main pumping chamber of a reciprocating pump are connected by a connector having an aperture, the perimeter dimension of which is less than the internal perimeter dimension of the flushing chamber. A flushing space is defined between the connector and the profiled plunger. The profiled plunger is reciprocatingly mounted through the flushing chamber, connector, and the main pumping chamber. The perimeter dimension of the profiled plunger varies along its length in a predetermined manner in order to create a predetermined flow profile of flushing fluid through the aperture of the connector.
