Pumps have either a cast bronze pump housing or a cast iron pump housing with a protective epoxy coating for corrosion resistance. The motor housings are filled with a dielectric oil (non toxic to aquatic life) for lifetime bearing lubrication and rapid heat dissipation. Cooler running motors extend motor life. These pumps are designed for continuous duty and can be used for a lot of applications such as: construction sites, fire cleanup, excavation, crawl spaces, basements, grain elevators, underground passageways, cooling towers, and other places requiring high volume water removal.
