Product Overview: DP Pump is a self Cbalancing multilevel boiler feed pump with single-suction, multievel and sectional structure. This series of pumps are suitbalbe for medium and low pressure boiler water feeding, and high-pressure boiler water feeding for thermal power plant, as well as high-lift water supply and drainage of factories and cities. They are used in transferring water or other liquid with similar physical and chemical properties to water. Temperature of media being transferred can vary from -20~160 Efficient energy-saving: Using advanced hydraulic model, independent R&D energy efficient products. Good centering of impeller and guid vane channel and efficiency will not significantly drop as balancing disc wears and rotor components move forward. No leakage of balancing water reduces loss of volume and improves pump efficincy and pump efficiency is on average 2-5% higher than normal DG pump. New structure: With symmetrically arranged impeller rotor components, axial forces generated by all levels of symmetrical impellers forces offset each other and automatic balancing of huge axial thrust within pump cavity can be realized without the balcancing disc structure. New technology: Unique throttling and pressure reduction devices, odd-lecel balancing device. High reliability: By canceling easy-failing balancing disc, pump reliability is greatly improved, maintenance frequency and maintenance cost are reduced. Low maintenance cost and long life time By adopting precision casting and unique throttling and pressure reducing devices for auxiliary support, pump vibration and noise are greatly reduced and service life is prolonged.

SD Self-balancing Multistage Centrifugal Pump has been innovated on the basis of the traditional forms, abandoning the axial force balancing structure of the multistage centrifugal. Since having no balancing device, there exists none disk friction losses nor balancing return losses, the pump efficiency has been increased by 5-14% than the same category multistage pumps.The pressure can be up to 200bar Product name : Self-balancing multistage pump Item : high pressure multistage pump Features : ---SD tpye horizontal multistage centrifugal electric pump ,introduced the technology from CLYDE UNION PUMP. ---No balance plate, so wider performance range. ---5%-15% higher efficiency than the old style common multistage pump. ---Directly coupled, vibration proof and low noise. ---Circulating flow cooling ensure mechanical seal long life. ---Excellent seal that is no leakage. ---work steadily and safety. ---Low noise,less easy-wearing parts and easy for maintaining.

D type cast iron and ss multistage boiler feeding pump and clean water pump D type multistage boiler feeding pump overview: It is widely applied to supply water of low or high pressure boiler. It is also used for high pressure water supply and drainage of industrial and urban. The temperature of medium delivered should be in the range of -20°c to 150°c and the water pump inlet pressure should be less than 0.6m pa. Product feature: 1. About d model pumps, inlet and exit are both vertically upward. The inlet section, middle section, discharge section and bearing body of pump are connected into one by tightening bolt. Customer can decide the pump stage according to pump head. 2. The rotor part of pump is composed of axis, impeller, shaft sleeve and balance disk, etc. The quantity of impeller is decided by the stage quantity of pump. The components of axis are connected by flat key and spindle nuts. The whole rotor is supported by antifriction bearing or sliding bearing. Balance disc bears axial force instead of bearing. When pump is running, the rotor can move in the same axial direction. Annular ball bearing can not be used about this series of pumps. They are adopted antifriction bearing. Antifriction bearing is lubricated by grease and sliding bearing is lubricated by thin oil. In addition, they can lubricate themselves by oil ring and cool themselves by circulation water.

Product introduction: VMP type a multistage centrifugal pump, may transport the temperature does not exceed 80 â?? freshwater and seawater. Product features: The structure is compact and reasonable, the installation covers an area of small, light weight, stable operation, easy maintenance, can prevent leakage of liquid to be delivered by a specially designed mechanical seal. The lift of the pump with the series increases in direct proportion to increase, and the corresponding flow will not change. Technical parameters: Lift5-173.2m Flow4-30m/h Field of application: Suitable for fire protection, refrigeration system, industry, agriculture, building water, deep well water, fresh water and sea transport
