The MWD hydraulic excavator for coal mines adopts an electric hydraulic system and is mainly used in conjunction with vertical shaft drilling rigs to realize the mechanized operation of vertical shaft tunneling in coal mines and other mines and greatly increase the speed of tunneling. At the same time, it can be used for auxiliary rock loading and excavation operations in flat and inclined roadways.

Our AODD pump is used in coal mines to discharge clean water or sewage containing solid particles (volume concentration less than 2%). It can also be used in non-coal mines and other occasions with similar conveying media.The product can provide high conveying speed under low air pressure and is compatible with a wide range of materials. This pump has an anti-stall design with modular air motor/fluid part.
