Debris evacuation apparatus and method for an oil pump

A method for evacuating debris from a pumping apparatus comprising the steps of:

• providing a debris evacuation apparatus comprising, in combination:
• a first seal positioned circumferentially about said debris evacuation apparatus;
• a first groove located south of said first seal;
• at least one port extending through said first groove to a passage within an interior of said debris evacuation apparatus;
• a main shaft located south of said first groove;
• a screw-in insert located south of said first groove;
• wherein said screw-in insert is open at a south end thereof to receive a flow of fluid, and wherein at a north end of said screw-in insert there is located a closed center section surrounded by a plurality of angled veins, so that fluid travelling north within said screw-in insert will be blocked by said center section and forced through said angled veins, with said angled veins imparting rotation to said fluid as it travels northward;
• pumping fluid through said debris evacuation apparatus;
• said fluid travelling northward through said screw-in insert and said passage;
• drawing debris in through said ports in said first groove;
• said fluid and said debris exiting a north end of said debris evacuation apparatus.
