Slurry pumps and slurry pumps mainly consider the anti-abrasion and anti-corrosiveness of pumps, which convey a higher percentage of solid, but the allowable particle size is relatively small. In the case of similar flow and head, it is certainly no problem to replace slurry pumps with slurry pumps. In fact, slurry pumps belong to slurry pumps, but the material of the starting and passing parts is not wear-resistant, and its price is higher than slurry pumps. It's much cheaper, so in general industrial and mining conditions, the proportion of slurry is very small, it's OK to use slurry pump. Slurry pump is mainly used in industrial and mining conditions with high concentration of slurry medium and strong abrasion, such as tailings discharging in concentrator, coal washing, ash removal in power plant, etc.
Sewage pumps are used to transport small amounts of solids or impurities. The solid content of slurry pumps or slurry pumps can reach 20% or more.
Generally speaking, if it is heavy medium, high concentration and serious abrasion, slag slurry should be selected. Slurry pump can also be divided into light slurry and heavy slurry. The reason of cost is that in general, if it is not submersible, there is no cost constraint, slurry pump is most suitable.
In the design of sewage pump, the passing capacity and corrosion resistance of impurities are considered. The concentration of impurities in the liquid is smaller than that in the slurry pump, but the particles can be transported larger. The trash can be transported through cloth strips, leaves and other garbage.
