Stainless steel sewage pumps come in various forms, including submersible and dry types. The most common submersible type is the WQF stainless steel submersible sewage pump, while the most common dry type is the PWF horizontal stainless steel sewage pump.
Based on the stainless steel material, they can be further classified as 304 stainless steel sewage pumps, 316 stainless steel sewage pumps, and 316L stainless steel sewage pumps. The corrosion resistance of these three types increases in that order, primarily depending on the nickel content of the stainless steel.
