Dayton centrifugal pumps employ an air-water mixture to reach a fully-primed pumping condition in self-priming applications. These pumps have fiberglass-reinforced thermoplastic body for operation in seawater & saltwater. Dayton centrifugal pumps are powered by a TEFC motor (capacitor-start or 3 phase) and feature thermal protection mechanism with automatic reset. The parts are made from thermoplastic, stainless steel, viton, carbon and ceramic for corrosion resistance and use with non-flammable liquids. They have double shielded pre-lubricated ball bearings for smooth operation. Choose from a wide range of centrifugal pumps, available in 1/2, 3/4, 1, 1.5, 2 and 3 HP power ratings on Raptor Supplies.
