1、 Comparison between stainless steel pump and cast iron pump
In the transportation of thiophanate, the corrosion resistance of cast iron pump is indeed higher than that of stainless steel pump, but in the transportation of weak acid, weak alkali and salt medium, the corrosion resistance of stainless steel pump is better than that of cast iron. For water pumps, the corrosion resistance of pump bodies made of different materials to different media is different. It cannot be simply said which material has better corrosion resistance. Generally speaking, the corrosion resistance of stainless steel is higher than that of cast iron. Since cast iron is cheaper than stainless steel, when the corrosion resistance of transmission media to the two materials is not much, cast iron is generally chosen.
2、 Material characteristics of stainless steel pump
Corrosion resistance
Stainless steel pumps have strong corrosion resistance and are very durable. Therefore, pumps made of this material are used in various working environments. Most stainless steel pumps made of high-strength materials are cast steel. Therefore, stainless steel pumps also have corrosion resistance of stainless steel. When using pumps made of this material, you do not have to worry about the impact of the external environment, This is also the reason why stainless steel is stainless steel pumps are suitable for various working conditions.
Good cost performance
The price of stainless steel water pump has a competitive advantage among the pump products of the same type. It not only has a high cost performance ratio, but also has the characteristics that other types of pumps do not have. Therefore, stainless steel water pump is a pump product with a high cost performance ratio.
Long service life
The quality of stainless steel water pump is also good compared with other pumps. The failure rate in the later use process is very low, and the later maintenance is also very simple. As long as the pump is maintained in normal operation, the maintenance time of the pump is very long, which can meet the user's requirements for long-term use.
