  Professional manufacturer of horizontal multistage pumps-Changsha Zoomlian Pump Co., Ltd.

The horizontal multi-stage pump is a multi-stage segmental centrifugal pump produced by Changsha Zoomlian Pump Co., Ltd. using the principle of centrifugation and adopting the hydraulic model of energy-saving products recommended by the country. It is suitable for mines, factories and urban water supply, For drainage. It is used to transport clear water without solid particles and abrasives, without suspended matter, or other liquids with physical and chemical properties similar to clear water. When the physical and chemical properties of the transport liquid have special requirements, the material of the pump can also be changed according to the special requirements to make the pump and the The physical and chemical properties of the conveyed liquid are compatible, and the performance parameters and installation dimensions of the pump after the material is changed are basically the same as those before the material is not changed.

 

   Horizontal multistage centrifugal pumps are mainly divided into the following types according to their scope of application:

  1, D-type horizontal multi-stage centrifugal pump: D-type pump is used to transport clear water without solid particles and temperature below 80℃, or liquid with physical and chemical properties similar to clear water, suitable for mine or urban water supply and drainage projects.

2. DF type corrosion-resistant horizontal multi-stage centrifugal pump: DF type pump is used for corrosive liquids with a temperature of 20℃~105℃ and no solid particles. It can also be used as a sub-high pressure boiler feed water pump. The allowable pressure at the pump inlet It is 0.6MPa. The user can reasonably select the pump material, sealing form, pump structure and determine the capacity of the motor according to the name, concentration, pump inlet pressure, use temperature and specific gravity of the conveying medium.

  3. DY type horizontal multi-stage centrifugal oil pump: DY type pump is used to transport oil and petroleum products that do not contain solid particles, the temperature is 20 ℃ ~ 150 ℃, and the viscosity is less than 120 centistokes.

  4. MD type mining horizontal multistage centrifugal pump: MD type pump is used to transport mine water and similar liquids with a small amount of solid particles, particle diameter less than 0.5mm, and temperature below 80℃.

5. DG type horizontal multi-stage centrifugal boiler feed water pump: DG type pump is used to transport clean water without solid particles and a temperature below 105 ℃, or liquids with physical and chemical properties similar to clean water, suitable for medium and small, medium and low pressure boiler feed water Or transport hot water and similar hot water media

The self-balancing multi-stage pump is a high-efficiency and high-pressure multi-stage centrifugal research and development developed by Zoomlion Pumps in order to meet the needs of users and accelerate the development of high-pressure multi-stage pump technology. Pump products; in a leading position in the industry. It has the advantages of wide high efficiency zone, wide performance range, good cavitation performance, safe and stable operation, low noise, few wearing parts, and convenient installation and maintenance.

The high-efficiency self-balancing multi-stage centrifugal pump has innovated the structure of the traditional multi-stage segmental centrifugal pump. The axial force balance mechanism of the multi-stage centrifugal pump is cancelled. The best new generation product of centrifugal pump.

The high-efficiency self-balancing multi-stage centrifugal pump has no balance device, that is, there is no balance disc friction loss and no balance return loss, so the pump efficiency is 5~14% higher than the same type of multi-stage pump, and it completely solves the failure of the balance device. Causes various failures such as the wear of the balance plate and the balance plate seat or the rotor seizure, which greatly extends the service life of the pump. The trouble-free running time is more than 3 times that of ordinary pumps, and the user maintenance cost is greatly reduced, thereby reducing the life cycle cost of the pump. Years of operation have proved that the performance of this product has reached the international advanced level of similar products.

  For conveying solid particles not more than 2% (particle size less than m), and the medium solid concentration is less than 5%Wt. Clear water with a temperature of ≤105℃ or other liquids whose physical and chemical properties are similar to clear water is used as a liquid. It can also be used to transport hot water, oil, corrosive or abrasive media, etc. with a temperature of ≤210℃ by changing the material of the pump or the material of the pump's flow-through parts), sealing form and adding a cooling system. There are ftT200, QT600, 304304L, 316L, 317L, 904L, CD4 and other materials for users to choose.
