Mining pneumatic dredging and sewage discharge pump

The mining pneumatic dredging and sewage pump is a purely pneumatic unit, specifically designed as a highly efficient dredging device for harsh environments such as coal mines. It utilizes compressed air passing through a Laval nozzle to generate negative pressure, enabling it to pump and discharge high-concentration slurries as well as loose solid materials. This innovative solution effectively eliminates the arduous manual labor involved in manually excavating water reservoirs, saving both time and effort.
