Multistage Centrifugal Pump

A multistage centrifugal pump is one that has multiple impellers mounted on the same shaft. These pumps can have smaller impeller diameters and clearances and still operate close to optimum hydraulic efficiency. As a result, these pumps require less energy and can be installed in tighter locations. This type of pump is used in applications where the fluid volume is very high and the pressure is low. There are two ways to install the impeller group. In the first case, the impeller group is located on the outside of the body. In the second case, the liquid flows through the upper part of the shaft.
The multistage centrifugal pump is usually used for a single application. It uses several impellers that impart energy to the fluid. Because each impeller is independent of the others, the pump is smaller than a single stage pump. The impellers are smaller, which allows the pump to have tighter clearances and tolerances. Moreover, this pump is able to handle a wider variety of liquids and uses less energy.
A multistage centrifugal pump is ideal for applications where the liquid is very viscous, and needs to be pumped to a high height. Although it costs more to purchase a multistage pump, the operating cost is much lower than a single stage pump. The head is increased as the liquid is transferred from one stage to the next. A high-performance multistage centrifugal pump can be used for a variety of applications.
A multistage centrifugal pump can be designed to achieve high outputs. The flow range for this type of pump is typically between 450 and 1500 m3/h. The maximum head will be around 1800 mHz. This design is larger than a segmented multistage pump and requires a complex casting process. In addition, the joints of horizontal split multistage pumps are difficult to work on. The main advantage is that the price is cheap.
A multistage centrifugal pump is a horizontal or vertical pump that has multiple stages. Each stage is designed to have smaller impeller diameters and clearances than a single stage. The lower pressure is achieved in the upper stage, which is usually referred to as a sub-stage. The multistage centrifugal pump is able to handle a wide range of fluids and increase pressure at each stage.
The multistage centrifugal pump can be a vertical or horizontal unit. They have a compact footprint and a harmonious appearance. The casing is made of aluminum alloy, which has low noise levels. Light chemical media are acceptable for use with this type of multistage centrifugal pump. This type of unit has a lower cost of ownership but higher operating costs. Further, it is able to handle a wider range of fluid volumes.
