D and DG horizontal multistage centrifugal pumps

1. Product overview of D and DG horizontal multistage centrifugal pumps:

   D. The DG pump is a horizontal, single-suction, multi-stage, segmented centrifugal pump. It has the characteristics of high efficiency, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc. For conveying clean water or other liquids with physical and chemical properties similar to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump flow parts, the sealing form and increasing the cooling system. The product implements the standard of JB/T1051-93 "Type and Basic Parameters of Multistage Clean Water Centrifugal Pump".

  All products of our company are designed and optimized by computer. The company has strong technical force, rich production experience and perfect testing methods, so as to ensure the stability and reliability of product quality.
2. Scope of application of D and DG horizontal multistage centrifugal pumps:

   It is suitable for industrial and urban water supply and drainage, high-rise building pressurized water supply, garden sprinkler irrigation, fire pressurization, long-distance water supply, heating, bathroom and other cold and warm water circulation pressurization and equipment matching, especially for small boiler water supply.
