Product Description1.GeneralBQS(QBK)Explosive-proof (Exdl) submersible slurry pumps can be used in hazardous underground mining condition, such as working face with high-methane content and/or high coal dust content. The pumps have a long service life with the components and sealing made of alloy with high rigidity.2. Main FeaturesThe slurry pump is wearable, and liable with tight sealings. It is comparatively energy saving. It is assembled with integrity of mechanical parts and electrical parts. So it is simple to install and easy to operate. This structure makes an excellent cooling efficiency. The pump has a unique feature, that it can dry run for some time (1-5hours) without making and damages to the engine, and it can resume pumping as soon as there is water.3. Main Working Scope3.1 Pumping water in the shaft and drift construction;3.2 Pumping water in the pit bottom water-free bunks;3.3 Pumping water in the coal mining development and work face;3.4 Pumping water in the pit bottom coal silos;3.5 Pumping water in goaf area;3.6 Pumping slurry in the water bunks;3.7 Used in the hazardous conditions in the oil and chemical in dustries;3.8 Pumping water in the flooded areas.4.
