The Zoeller M98 is a durable cast iron submersible sump pump finished in corrosion‑resistant epoxy. It uses a float‑activated mechanical switch and an oil‑filled hermetically sealed PSC motor with automatic thermal overload protection. Upper and lower oil‑lubricated bearings and a carbon‑ceramic shaft seal increase reliability. The engineered vortex plastic impeller passes 1/2 inch solids and the unit has a 1.5 inch NPT discharge, 115V operation, and a 130°F (54°C) maximum fluid temperature. The
