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 12):
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 an upper screen housing adapted to be coupled to a southern end of a top plunger adapter, wherein the upper screen housing comprises:\n a cylindrical body with a center channel formed therethrough; \n a screen housed within the body of the upper screen housing; and \n a plurality of apertures extending through the body of the upper screen housing into the center channel of the upper screen housing; \n \n a lower screen housing coupled to a southern end of the upper screen housing, wherein the lower screen housing comprises:\n a cylindrical body with a center channel formed therethrough; \n a screen housed within the body of the lower screen housing; \n a plurality of apertures extending through the body of the lower screen housing into the center channel of the lower screen housing; and \n a plurality of circular grooves formed on an outer surface of a top portion of the lower screen housing and positioned above the plurality of apertures of the lower screen housing; \n \n wherein the screen of the upper screen housing and the screen of the lower screen housing each have a polygonal shape, wherein an outer surface of the screen has multiple straight edges; \n passing dirty pumped fluid upwardly through the lower screen housing during a downstroke; filtering the dirty pumped fluid through the screen housed within the body of the lower screen housing; evacuating clean fluid out of the apertures of the lower screen housing; continuing to pass the dirty pumped fluid upwardly through the upper screen housing during the downstroke; filtering the dirty pumped fluid through the screen housed within the body of the upper screen housing; and evacuating clean fluid out of the apertures of the upper screen housing.
