Application�Industries, facilities, etc., to handle sea（salty） water such as�●Salty water pool�●Aquarium�●Fish market

●Fisherie's experiment station�●Fish pond�●Marine products processing factory

Sea water contains many kind of chloride and high electric conduction �

which causes chemical corrosion, electro chemical corrosion, corrosion �

and erosion caused by velocity and bacterial corrosion, etc., giving �

a damage to the pumps.�

Kawamoto sea water pump“KAWA-HOPE”series are designed to �

withstandagainst these corrosive factors adopting anti-corrosive �

materials such as titanium, high chlome stainless steel, and egineering�

plastics, putting special treatment such as nylon coating and epoxy resin, �

and installing sacrificial anode depend the pump type and construction.
