SUBMERSIBLE SEAWATER-RESISTANT SEWAGE PUMPS

Selection Table Submersible Seawater-ResistantSewage Pumps Handling seawater with submersible pumps for a long term period is not an easy task. When pumps are not equipped with adequate specifications for use in seawater, corrosion in metal sections may cause the pumps to become worse in terms of performance, or in the worst case scenario, suffer a breakdown. Supported by demonstrative experiments using seawater over a long time, Tsurumi has continued unremitting research into submersible seawater-resistant pumps, combining both corrosion resistance and durability. As a result, by giving the...

Mechanism of Metal Corrosion If seawater-resistant measures are not taken in seawater applications, metal parts corrode, which causes performance drop that can result in pump failure. One suspected cause of corrosion in metallic parts by seawater is the “metal corrosion potential.” In seawater, a metal’s resistance to corrosion can be seen clearly. As shown in the illustration of <Bimetallic Corrosion in Seawater>, when metals of different potential contact one another, only the metal of lower potential will corrode while the metal of higher potential is protected from corrosion. The table of...
