Series HY200 is single coil spring seal with rubber bellow mainly for use in waste water treatment plants in the sewage applications. The rubber bellow protects the shaft/ sleeve from fretting. The bellows are not subjected to any torsional stress. Torque transmission is through the spring and spring holder. Self aligning features accommodate abnormal shaft run out and primary sealing wear. The single coil spring will avoid effluent particles.
