Stainless steel submersible pump classification
Stainless steel submersible pump: As the name implies, 201 stainless steel, 304 stainless steel, 316L stainless steel and other materials using finishing, drawing, welding and other different processes of production, processing into the water has reached the pumping medium for the purpose of the pump, at present in the The market is widely used. Its characteristics are: beautiful appearance, low noise, no leakage, long life, high performance, stable operation and other characteristics, according to different application requirements, the advantages shown by the more prominent. Depending on the medium being pumped, stainless steel submersible pumps can be subdivided into different sub-categories. In pumping well water, fountains, pressurized water systems, etc., SJ (P) stainless steel deep well pumps are generally preferred for good performance Choice, which features high efficiency, high reliability, compact structure, low noise, the use of long operating life, etc., at the same time to meet the health requirements. 316 material pump for corrosive liquids. According to the user's environmental requirements, QXF, SPS and other stainless steel pump is also a good choice. Stainless steel submersible pump, also known as stainless steel sewage pump, the main application and the environment is relatively harsh, the medium has a certain corrosive, at the same time, according to different media, such as: medium containing solid particles or fibrous material, the medium temperature is relatively high , But also can be derived as a stainless steel cutting sewage pump, stainless steel mixing sewage pump, stainless steel high temperature corrosion-resistant submersible pumps and other types. According to the different media, choose a different type of stainless steel submersible pump, pump can maximize the excellent performance, to meet the application conditions, so the selection of the pump is particularly crucial.
