How to choose a pump with a large amount of impurities

How to choose a sewage pump that can transport sewage containing a large amount of impurities? Impurities need to consider whether they are large particle solid impurities or fibrous impurities.

The most important consideration for impurities containing solid particles is the passing performance of the impeller. Both open impeller and non clogged impeller can pass solid particles well. Non clogged submersible sewage pumps and non clogged self-priming sewage pumps are good choices.

For fibers containing impurities, the cutting performance of the impeller should be considered. Cutting the impeller can crush impurities and discharge them. Cutting type submersible sewage pump and cutting type self suction sewage pump can both be good choices.

In addition, it is necessary to consider whether the maintenance of the sewage pump is convenient and whether the cost of replacing accessories is high. The detachable cleaning design and replaceable wear-resistant disc can effectively solve the above problems.
