What is the difference between single-stage and multistage KNOLL centrifugal pumps? Centrifugal pump technology

2023-09-21 16:37:22

Centrifugal pump process:


The centrifugal pump operation cycle begins when the pump directs the fluid to its suction inlet and forwards it to the inlet of its impeller. The rotating impeller then moves along its rotating blades to pump the liquid while increasing the fluid speed.




The "charged" fluid then leaves the impeller blade and is directed to the diffuser housing or pump volute, where the high fluid velocity generated from the impeller blade is converted to high fluid pressure. Finally, the pressurized fluid is directed to an outlet or to the next stage of a multistage pump system.




The difference between single-stage and multistage centrifugal pumps:


The classification of centrifugal pumps depends on the number of impellers present in their device.




Single stage


This type of pump has only one impeller inside the housing, so maintenance is very easy. Single-stage centrifugal pumps are best suited for low-pressure operations where large flow rates are maintained.




bipolar


The two stage centrifugal pumps have two impellers that work together to pump the related process liquid. It is the most suitable device for medium head applications.




multistage


This centrifugal pump system requires multiple impellers (three or more) to achieve maximum efficiency. Multistage pumps are best suited for high head applications.




The above content introduces the difference between the single stage and the multi-stage of different types of KNOLL centrifugal pumps, and the process problems of centrifugal pumps.
