general informa Tion The Multiquip Model ST41230/ST41460 and ST61230/ ST61460 submersible pumps are designed to pump water. These pumps work best when faced with high head applications where you need an appreciable flow. The pumping of flammable, toxic, corrosive, abrasive liquids is strictly forbidden. These pumps are best suited for clear water applications where maximum size of solids (debris) does not exceed 0.6-inches (15.2 mm). These pumps have a chrome steel body that is very durabl
