AH Series custom seals are designed to eliminate process of setting seal face pressures. Seals are used on ribbon blenders, paddle mixers, rectors, screw conveyors, bucket elevators and similar blending or conveying machinery and can even replace lip seals to isolate lube oil in bearings. Available split or unsplit, seals are ideal for abrasive powder processes in food and pharmaceutical industries where frequent product changes and wash downs are required. Seals are fitted with flush water inlet and drain ports for in-place clean outs. Heavy, 1/2" stainless plate stators ensure flatness and long life, despite extensive handling.
