3、loped on the basis of the repeated research on the same know- how of both at home and abroad. This pump integrates self- suction and non- clogging and uses axial- back flow outside- mixing type and, through the unique design of both pump casing and impeller geat, needs not to mount a foot valve and
4、prime the leading water just like the common self- suction pure water pump and also can pump the liquid containing the solid of big grains and long fiber impurities. Compared with the same domestic products, this pump features a simple structure, good self- suction performance, strong sewage drainin
5、g capacity, high efficiency, energy saving and easy use and repair, with every technical performance index of it ranking first nationally among the sewage pump series products and up to the world advanced level, and holds a wide applicable market and progressive future.

10、ing hole on the lower to form the axial- back flow outside mixing type system of the pump. Liquid of a certain volume has been stored in the storing ca- vity after the pump stops working and, under the action of the impeller when the pump starts, is thrown out upwards with air and then flows back to
11、 the working cavity through the grids of the air- liquid separating pipe, the air is exhausted out of the pump to have a certain vacuum formed inside of the pump so as to get the self- suction action.
