D, DF, DY series of sub-horizontal single-suction multi-stage centrifugal pumps, using the state recommended hydraulic model of energy-efficient products. High efficiency, performance, wide range of security and smooth operation, low noise, long life, easy installation and maintenance and so on. Available for non-delivery of solid particles (abrasive), free of suspended solids of the physical and chemical properties of water or other liquids like fresh water use. Can also be material by changing the pump (or pump over-current part of the material), seal the form and increase the cooling system for conveying water, oil, corrosive or abrasive-containing medium, etc..

  Horizontal multi-stage centrifugal pumps according to their scope of use can be divided into the following types:

  1, D Type: D Series pumps for distribution does not contain solid particles, the temperature below 80  in water or similar physical and chemical properties of liquid fresh water. Suitable for mines, factories and urban water supply and drainage purposes.

  2, DF-type: DF Series pumps for distribution does not contain solid particles, the temperature is -20  ~ 105 corrosive liquids, pump pressure to allow imports of less than 0.6MPa. Users can transfer medium according to the name, concentration, specific gravity, temperature and pump inlet pressure pump such as a reasonable choice of material, sealed form, the pump structure and determine the capacity of the motor and so on.

  3, DY Model: DY series of pump used for delivery does not contain solid particles, the temperature is -20  ~ 105 , viscosity of less than 120 cSt oils and petroleum products. 4, MD (or the DM-type): MD (or DM) series for the delivery particle concentration ≤ 1.5%, particle size ≤ 0.5mm, the temperature of -20  ~ 80  medium-sized mine water and other similar sewage. Performance range: Flow Q = 6 ~ 650m3 / h Head H = 24 ~ 650m
