Multi-stage centrifugal pump can be divided into horizontal multi-stage centrifugal pump, vertical multi-stage centrifugal pump, corrosion-resistant multi-stage centrifugal pump, high temperature multi-stage centrifugal pump, wear-resistant multi-stage centrifugal pump , High-pressure boiler multi-level feed pump, industrial boiler multi-level feed pump.
Now to the use of these multi-stage centrifugal pump and the media to carry out to explain: DG-type high-pressure boiler multi-stage centrifugal pump can transport high-pressure boiler water, but also transport water, the maximum temperature of 170 ℃. DG type industrial boiler multi-stage centrifugal pump for medium and low pressure boiler water supply, factories, urban high-lift water. For the delivery of water or physical, chemical properties similar to the liquid water, transport medium temperature. DM-type wear-resistant multi-stage centrifugal pump is mainly used for mining, DF pump for single suction, multi-stage, segment corrosion-resistant centrifugal pump, suitable for conveying non-solid particles of corrosion-resistant liquid.
At present, China has been able to develop various models of multi-stage centrifugal pump, self-balancing multi-stage centrifugal pump, this new pump than the old multi-stage centrifugal pump has a higher performance, more energy efficient, more environmentally friendly and a series of advantages.
As China has been able to produce various types of multi-stage centrifugal pump, so that multi-stage centrifugal pump is not the manufacturers, but the market.
For domestic production of equipment can not generally have two cases: First, foreign patent equipment, domestic research in this technology is completely unnecessary; Second, from scratch design and production, this research and development difficulties, more harm than good. These two cases, Baiyun pump generally recommend users to buy foreign products directly.
But some domestic equipment in the price is very advantageous, especially the domestic pump accessories lower than the foreign and because the domestic pump manufacturers mature, the quality is much higher than the high parts, the general price of domestic accessories only similar foreign accessories Of the 50%, while the other price difference is greater.
There are many users do not believe that the quality of domestic settings, always think that the quality of the domestic pump, but very subjective that foreign is better than the domestic, blind purchase, which is the domestic pump sales market growth slow reasons.
