Abstract
A slotted pipe is rotatably supported in a drag tank and communicates with the suction line of a pump. Magnetic discs are rotatable with the pipe and serve to attract and catch magnetic particles in liquid flowing to the pipe so as to prevent such particles from entering the pump. A scraper is positioned adjacent the rotatable discs and pipe to brush the caught particles therefrom and direct the particles to the bottom of the tank.
