QYF25-50 mine pneumatic dredging sewage pumps, new product QYF mine pneumatic dredging sewage pumps, sewage pumps pneumatic dredging, mining dredging pump, QYF mining dredging pump, coal dredging pumps, pneumatic pump dredging full pneumatic dredging pumps significantly reduce tariffs or zero tariffs, QYF dredging pump surface mining countries would reduce tax revenue, but the backlog of coal produced high energy needs of the country in fact put into financial subsidies. So, if you want reckoning, then, a substantial reduction of tariffs, increase coal exports in the international market competitiveness, new products QYF mine pneumatic dredging sewage pump can not only resolve the capacity to play a positive role in alleviating the country held responsible for the financial subsidies to pressure, is also good. I. Overview: This product is the use of vacuum principle, the slime slurry tank inhaled materials, reuse materials to drain away the pressure of the wind, its advanced aerodynamic concepts make mine pneumatic vacuum dredging sewage pump up to international standards, Second, the main features: 1, pure pneumatic equipment, safe and reliable. 2, tub-type or tire type, 3 quick and easy installation, no-load operation of the pump without any harm, and stable performance. 4, can be pumping high concentrations of solids slurry and loose. 5, all stainless steel, acid corrosion, wear resistance. The successful development of the dredging crew not only to fill the gaps in some areas of domestic equipment, but similar to existing equipment also has a strong alternative for the petroleum, chemical, coal, municipal, construction and other industries to provide a dredging equipment new choice to break the monopoly of foreign companies, the market prospect.
