Can vertical submerged pump transport sewage? from luolintec's blog

Most types and specifications of vertical submerged pumps cannot handle wastewater with complex composition. At the beginning of the design, the vertical submerged pump was designed to treat pure water liquid without particulate impurities and fiber waste. If sewage is forcibly sucked in, it may accelerate the wear of the pump body, and there is a risk of blockage.

Whether the vertical submerged pump can transport sewage, if it is only a liquid containing fine particles, a wear-resistant mechanical seal can be customized in advance. However, if it contains larger solid particles or long-fiber waste, the vertical submerged pump cannot be used for suction. The main advantage of the vertical submerged pump is that the displacement is very high when delivering clean water. If it is used to pump sewage with complex parts, it will easily block the pump chamber, which may cause the motor to overload. If you need to pump sewage, you can use a sewage pump or a screw pump according to the situation.

On the whole, the vertical submerged pump is used to transport pure water liquids with relatively simple components, including corrosive or toxic chemicals, but cannot pump sewage. If you want to quickly treat sewage, it is recommended to choose according to the working conditions and requirements For sewage pumps, if the proportion of sewage is high, and the viscosity even exceeds the operating standards of general sewage pumps, single screw pumps specially used to handle complex media can also be considered.
