Are Cast Iron Pumps More Resistant to Corrosion Than Stainless Steel Pumps?

Are Cast Iron Pumps More Resistant to Corrosion Than Stainless Steel Pumps?

When conveying concentrated sulfuric acid, the corrosion resistance of cast iron pumps is indeed higher than that of stainless steel pumps, but when conveying weak acid, weak alkali and salty media, the corrosion resistance of stainless steel pumps is better than that of cast iron pumps. Different pump body materials The corrosion resistance of different media is different. It is not easy to say which material has better corrosion resistance. In general, the corrosion resistance of stainless steel is higher than that of cast iron. Because cast iron is cheaper than stainless steel, when When the conveyed medium does not have much corrosion performance for the two materials, the cast iron material is often selected.

Features of stainless steel pump material:

1. Corrosion resistance

Stainless steel pumps have strong corrosion resistance and are also very durable. Therefore, pumps of this material are used in a variety of different working conditions. Most of the materials used in stainless steel pumps are cast from high-quality steel. Therefore, the stainless steel pump also has the corrosion resistance and wear resistance of stainless steel. When using this material, there is no need to worry about the influence of the external environment on the pump. This is also the stainless steel pump used in a variety of different working conditions. s reason.

2. Good price/performance ratio

The price of stainless steel pumps has a competitive advantage among the same type of pump products. Not only is the cost-effective, but also has characteristics that other types of pumps do not have. Therefore, the stainless steel multi-stage pump is a very cost-effective pump product.

3. Long service life

Compared with other water pumps, the quality of stainless steel pumps is also good. The failure rate is very low in the later use process, and the later maintenance is also very simple. As long as the water pump is well maintained during normal operation, the use time of the water pump is very long. Long, can meet the user's long-term use requirements.
