ABSTRACT OF THE DISCLOSURE This invention consists of a novel filter combination which is disposed and adapted to be placed within a centrifugal pump between the impeller and the mechanical seal or packing thereof, for the purpose of protecting the mechanical seal or packing therein from the contaminants in the liquid being pumped by the centrifugal pump, the device consists of a plurality of annular rings, joined by means, each having vents around the circumferences thereof. The rings are designed to utilize the angular motion of the fluid and the forces on the contaminants induced by the rotation of the impeller, shaft and seal of the centrifugal pump, to remove contaminants from the fluids entering the area of the mechanical seal and thus prolong the use-life of the seal, this invention may be used in any adaptable existing centrifugal or other pumps, as a retro-fit.
