Ordinary pipeline centrifugal pump is designed to obtain the highest efficiency, that is to say, pipeline centrifugal pump of hydraulic structure parameters is to obtain the best combination of highest efficiency. For other pumps, pump of this kind of special requirement its efficiency can not be more than the same period of water self-priming pump efficiency. 

 

Other pump self-priming pump efficiency is lower than the water of the main reason is that they flow road widened, efficiency decreases the value of the main related to widen the extent to which. Other pump flow channel widening is to prevent blocking. 

 

IS, IH type pipeline centrifugal pump for conveying water or physical and chemical properties similar to water other liquid, the temperature IS not higher than 80 ℃. Main use is applicable to industrial and urban water supply, water drainage, can also be used for agricultural irrigation and drainage. The pump design chooses the excellent hydraulic model adopts the IH centrifugal pump performance parameters, on the basis of the general vertical centrifugal pump for clever combination design at the same time according to different use, such as temperature, medium derived based on ALG type, corrosion resistant chemical pump, oil pump for hot water. This series of products have the advantages of high efficiency and energy saving, low noise, reliable performance conforms to the latest national machinery JB/T53058-93 standard requirement. Can transport water and physical and chemical properties of similar Yu Qingshui other liquid with applicable to industrial and urban water supply and drainage, pressurized water supply in high-rise building, garden sprinkler irrigation, fire pressurization, long-distance transmission, hvac refrigeration cycle, cold and hot water circulation pressurization in the bathroom, etc, and form a complete set of equipment, using temperature T < 80 ℃. 

 

Hot water centrifugal pump is applicable to the metallurgical, chemical, textile, wood processing, paper making, bathroom, hotel and hotel and so on boiler high temperature hot water pressurization circulation and urban housing heating circulation pump use temperature below 120 ℃. 

 

Self-priming pump is widely used in high temperature water, energy, metallurgy, chemical industry, textile, papermaking, bathroom, hotel and hotel and so on boiler high temperature hot water pressurization circulation and urban housing heating circulation pump use temperature below 240 ℃.
