ZW self-priming non-clogging sewage pump

product description
ZW type self-priming sewage pump is a collection of self-priming and sewage, which can be used like ordinary clean water self-priming pumps without the need for bottom valve, no need to irrigate water, and can suck solid particles containing large particles with a diameter of 60% of the outlet diameter And dirt, sediment, waste ore impurities, manure treatment and all engineering sewage and colloidal liquid whose length is 1.5 times of the impeller diameter, completely reduce the labor intensity of workers, and it is easy to use, move and install, and requires very little maintenance Stable performance.
