DESCRIPTION

Complete repair kit for the ShinMaywa CNWX explosion-proof submersible sewage pump at the 3 HP and 5 HP ratings — both mechanical seals and the full O-ring set in one box. The CNWX runs a tandem double seal, upper and lower, and we supply both with silicon carbide on every face rather than dropping the upper to a carbon face. Sized for the 35mm shaft. Check the nameplate against the model list below before ordering.
