Abstract: A cartridge seal assembly includes an outer housing including a first tubular segment having a first axial end and a second axial end, and a first flange extending radially inward from the second axial end; an inner housing including a second tubular segment having a third axial end and a fourth axial end, and a second flange extending radially inward from the fourth axial end; and a first seal ring having a first tapered inner circumferential surface that defines a first passage through the first seal ring. The inner housing is removably secured to the outer housing, and the first seal ring engages a portion of one of the inner housing and the outer housing.
