Products overview:

High mining horizontal multi-stage suction pumps are mainly used for mine main drainage pump. Is my company summary to mine main drainage pump application experience for many years, application of three-dimensional pump design patent products of technology development. Previous large flow mine multistage pump suction under normal atmospheric pressure 4 meters, is especially big flow pump, NPSH in 5-6 m above. In the high altitude atmosphere, lower suction only 2 to 3 meters. Water pump can't work normally, the water pump cavitation resulting damage, influence of the mining production. And our high mine multistage pump suction. NPSH within 1.5 2.5 m, can reach 8 meters. And there's no need to increase the power of form a complete set. Don't make it easy to pump water diversion, the water pump cavitation, water warehouse design constraints, is mine main drainage pump updated products.

Structure description:

D, DG, MD, DF series high suction pump for horizontal installation, such as inlet horizontal vertical upward (DG), discharge vertically up. Pump suction, middle, spit out paragraphs with tighten bolts connected into a whole. By suction pump, impeller, shaft, middle, spit out paragraphs, guide vane, guide vane and the major parts of the balance disc, etc. Axial force of the rotor by the balancing disc, bearing adopts rolling bearing, grease lubrication. Using packing seal or mechanical seal of the shaft sealing system. In a sealed cavity zhongtong into a certain pressure water seal water. From the driving end, pump is clockwise.

Performance range: traffic: 60-1450 m3 / h head: 90-1990 m

Main application:

Type D high suction single-suction multi-stage horizontal centrifugal pump can transport clean water or other physical and chemical properties of similar Yu Qingshui liquid. Medium temperature is not more than 80 ℃, it is suitable for the mine drainage and factories, the urban building supply, water over a long distance, etc.

DG high suction single-suction multi-stage centrifugal pump for conveying water or hot water physical and chemical properties of similar Yu Qingshui other liquid. Medium temperature is not more than 105 ℃, suitable for small boiler feed water or hot water and hot water like medium. Also can according to user requirements production of medium temperature is not more than 150 ℃.

MD type high single-suction multi-stage wear-resisting suction pump is designed based on the D type pump to improve a wear-resisting multistage centrifugal pump. MD type pump efficiency, good abrasion resistance, long life, especially suitable for the mine drainage, conveying solids content is not more than 1.5% (particle diameter less than 0.5 mm) of mine water, and other similar liquid, the liquid temperature is not higher than 80 ℃.

DF type high single-suction multi-stage suction pump for conveying the corrosion temperature - 20 ℃ 105 ℃ not containing solid particles, corrosive liquid. Mainly used in chemical, petroleum, metallurgy, light industry, printing and dyeing, pharmaceutical, environmental protection, water desalination. Offshore oil and mining industries.
