The stainless steel corrosion pump is non self priming vertical multistage centrifugal pump. The motor shaft is directly connected to the pump shaft through the coupling. The impeller guide blade is made by stainless steel plate stamping or stainless steel precision casting, and the pump inlet and outlet is on the same line of the pump bottom (with IEC or NEMA motor).

In addition to atmospheric conditions, there are two other factors that affect the corrosion resistance of stainless steel, namely, surface state and fabrication process. The finishing level affects the corrosion resistance of stainless steel in the environment with chlorides. The non - optical surface (wool surface) is very sensitive to corrosion, that is, the normal industrial finishing surface is less sensitive to corrosion. The surface finishing level of the stainless steel corrosion resistant pump also affects the removal of dirt and rust. It is easy to remove dirt and rust from a highly refined surface, but it is difficult to remove it from a surface without light. For non - optical surfaces, more frequent cleaning is needed if the original surface state is to be maintained. Stainless steel chemical pump

Carbon steel equipment under the action of acid water is usually quickly corroded. The results of experiments with various materials affected by acid water show that the austenitic stainless steel has high corrosion resistance in this environment. Austenitic stainless steel has excellent corrosion resistance in fresh water and acid water, especially its corrosion film has little obstruction to heat conduction. Therefore, stainless steel tubes are widely used in the use of heat exchange.

The corrosion rate of 1Cr17 stainless steel is slightly higher than that of 0Cr18Ni9, and the higher temperature and concentration have a greater harmful effect on it. If the heat treatment of the stainless steel corrosion resistant pump is not appropriate, the hot nitric acid will cause intergranular corrosion of austenite and ferritic stainless steel. Therefore, appropriate heat treatment can be used to prevent this type of corrosion, or to use stainless steel that is resistant to this type of corrosion.
