D, DG, DM, DF, DW-type multi-stage centrifugal pump

I. Overview

D-type pump is a single-suction multi-stage centrifugal pump for conveying water and physical and chemical properties similar to the use of liquid, transmission medium temperature does not exceed 80 ℃, suitable for factories, mines, urban and rural water supply and drainage purposes.

DG pump is a single-suction multi-stage segmental boiler feed pump, it is the replacement product of GC type boiler feed water pump. The temperature of conveying medium does not exceed 105 ℃. It is suitable for various medium and low pressure boiler feed water or similar hot water. .

DM-type pump is a single-suction multi-stage segmental mining centrifugal pump, is based on the D-type pump modified design. Balance the drum structure with axial force, can transport impurities less than 1%, particle size is less than 0.1 mm of liquid, change the flow components can be pumped weak acid or weak base liquid. Transmission medium maximum temperature does not exceed 80 ℃. Applicable to a variety of mine water supply and drainage, all kinds of sugar mills, steel mills, paper mills and other water supply and sewage.

DF pump is a single-stage multi-stage corrosion-resistant pump for conveying non-solid particles, the temperature is -20 ℃ ~ +105 ℃ corrosive liquid, pump inlet pressure is less than 0.6MPa. Mainly used in chemical, petroleum, metallurgy, light industry, printing and dyeing, pharmaceutical, environmental protection, desalination, offshore oil and mining and other fields.

DW-pump is a micro-pressure winding sealing energy-saving multi-stage centrifugal pump, is an old Great Pump Energy Co., Ltd. innovative design, and our factory successfully developed a centrifugal pump, the pump industry with China pump manufacturing technology, From the pump to improve the volumetric efficiency and mechanical efficiency start, so as to improve the efficiency of the pump to achieve the purpose of energy saving. The series of pumps meet the JB / T1051-1993 "multi-level clean water centrifugal pump type and basic parameters" standard, the use of excellent hydraulic model, energy efficient; low vibration, low noise; shaft seal with packing seal, according to user requirements of different filler . For the transmission of water and physical and chemical properties similar to the use of liquid water, transmission medium temperature does not exceed 80 ℃, suitable for factories, mines, cities, rural water supply and drainage purposes.
