Elastic rubber diaphragm seals series aes, 024 is single coil equipped with a flexible rubber bellows mainly designed for application in wast water filtration stations in the sewage applications. The rubber bellow protects the shaft / sleeve from fretting. The bellows is not subjected to any torsonial stress. The mechanism for torque transfer is through the spring and spring holder. Self aligning features accomodate abnormal shaft runout and primary sealing wear. The individual coil spring will avoid effluent particles.
