It is a pump used to transport high-concentration sludge or liquid containing particulate matter. It uses the rotation between two relatively moving rotors to suck the liquid from the inlet and then push it to the outlet through the rotation of the rotors. Rotary lobe sludge pump s are usually used in sewage treatment plants, sludge treatment equipment, chemical plants, mining and metallurgy, food and beverage, paper industry and other fields to transport high-concentration and high-viscosity media such as sewage, sludge, and wastewater. Due to its special design, the Rotary lobe sludge pump can effectively handle media containing particulate matter. Its advantages include strong adaptability, high efficiency, reliability and stability, wear and corrosion resistance, energy saving and environmental protection, etc. Therefore, it is widely used in industrial production and environmental protection. plays an important role.
