Sethco Magnetic Drive, Sealless, Self Priming Pumps feature Kynar construction for use in corrosive liquid applications. All pumps incorporate a special 99.5% Alumina ceramic shaft and appropriate o-rings. There is no metal contact with the liquid being pumped. Since the pump is magnetically driven, no shaft seal is required. Power is transmitted by a magnetic field from the magnet attached to the motor through the solid body of the pump to the magnet attached to the impeller. No shaft seals means no seal leaks and no air leaks. Leakage and troublesome seal replacement are completely eliminated.Priming the pump is easy. The operator simply fills the priming chamber with the liquid to be pumped and turns the pump on. Other features include the ability to run dry after initial priming, easy to disassemble design and an internal basket strainer to prevent foreign objects from entering pump. Completely corrosion resistant, the pump is recommended for acids, alkalies, caustics, sea water, solvents and many other difficult applications.
