Abstract:
A screen filter assembly has an upper screen housing and a lower screen housing, both of which contain screens to filter solids from dirty production fluid. The lower screen housing has a plurality of circular grooves that trap solids therein, thereby helping to prevent the solids from falling downward toward the plunger. In an embodiment, the lower screen housing may include a plurality of rings that seal off the area between the upper screen housing and the lower screen housing, thereby preventing any cleaned fluid produced by the lower screen housing from mixing with any contaminated fluid above it. In another embodiment, a screen filter assembly is incorporated into a full-length plunger, which contains a screen to filter solids from dirty production fluid. By filtering dirty production fluid, the screen filter assembly keeps the solids off of the plunger and away from the pump barrel.

Claim (Index 28):
A method for filtering solids within a pump barrel of a pump system comprising the steps of:\n providing a screen filter assembly comprising:\n a plunger, wherein the plunger comprises:\n a top portion; \n a body; \n a center channel formed through the top portion and through the body; and \n a plurality of apertures extending through the body into the center channel; and \n \n a screen housed within the body of the plunger; \n passing dirty pumped fluid upwardly through the plunger during a downstroke; filtering the dirty pumped fluid through the screen; evacuating clean fluid out of the apertures of the plunger; and continuing to pass the dirty pumped fluid upwardly through the center channel of the plunger during the downstroke.
