Areas of application for multistage pumps

The use of multistage pumps is reflected in the high head water transport, the pump essentially belongs to the centrifugal pipeline pump, in the use of similar, suitable for industrial production and urban water system, commonly used for pressure transport, long-distance water transport, high-pressure flushing, cooling and heating cycle water transport, etc., can be highly efficient handling of all kinds of non-particulate liquids, including acid and alkaline liquids.

Simply put, multistage pumps are used in the same way as centrifugal pipeline pumps, they only differ in structural design and have different performance parameters for different transport needs. A multistage pump is a pump with multiple impellers in the pump cavity, which can have a higher head compared to general centrifugal pump products, with a head of over 125 metres, suitable for high head occasions. Because of the complex internal structure compared to the general pump, it is slightly more expensive in terms of cost. If the transport project does not have a higher head need, it is not recommended to deliberately choose a multistage pump.

In order to facilitate you to have more intuitive understanding of the use of multi-stage pumps, the following is a brief introduction to two common models of multi-stage pumps.

CDLF series light stainless steel vertical multistage pumps: centrifugal multistage pumps using standard vertical motors and quick-fit mechanical seals, suitable for transporting mildly corrosive media such as mineral water, softened water, pure water, clear oil and other non-flammable and explosive media that are thin, clean and do not contain solid particles or fibres. To improve the overall operational stability of the pump, the shaft seal is made of hard alloy and fluorine rubber, and the production process is optimised to provide the pump with a long service life, and if required an intelligent protector can be configured to prevent abnormal working conditions such as idling, water shortage and overload.

CHLK light stainless steel multistage pump: a small, light multistage pump with maintenance-free mechanical seals, low noise during operation, small size so there is no excessive vibration, resistant to mild corrosion and can run for long periods. It is suitable for transporting thin, clean, non-condensable, non-explosive liquids that do not contain solid particles or fibres, and has a temperature range of -15°C to +70°C for the ambient type and +70°C to +110°C for the hot water type, and can be adapted to an ambient temperature of up to 40°C. In terms of performance parameters, the calibre range is 25-50/25-50mm, the flow range is 0-28m3/h and the head range is 0-65m.

In summary, a brief introduction to the use of multi-stage pumps, users can choose according to their actual needs, if you are interested in knowing more such as screw pumps, sewage pumps and other related pump products, you can continue to pay attention to zhaoquan pump industry.
