An excellent choice for providing seawater circulation for marine air conditioning systems. The proven magnetic drive eliminates the troublesome mechanical shaft seal. The impeller and drive magnets are strong, permanent ceramic types, which prevent slippage, insuring that full motor power is converted into pumping power. Requires a flooded inlet and must be mounted below the waterline. Comes with a 6′ power cord. Air-cooled, open drip-proof motors and must be in a dry environment.
