What is a Multistage Pump?

A multistage pump is a siphon wherein the liquid courses through at least two impellers fitted in series. As a result, a pump of this kind will have several stages or liquid chambers connected in series. An impeller, a diffuser, and return guide vanes are all contained within the same stage casing for each stage.

These impellers are connected in series and rotate on a single shaft that is powered by a motor or other power source. The fluid can only move linearly through the chambers of multistage pumps because of their design.

How Do Multistage Pumps Work?

After priming the pump, the fluid enters the pump inlet at suction line pressure into the first chamber. The fluid then passes through various impellers sequentially from left to right (or vice versa, depending on the design of the pump). Finally, the fluid leaves at some elevated pressure. Each impeller feeds into the next impeller, and at every stage, the pressure increases further.

The more the number of stages or impellers in a pump, the higher is the final discharge pressure. Although the fluid pressure increases with every stage, the flow range always remains constant for a given RPM.

Benefits of Using Multistage Pumps

• 
  

  A multistage centrifugal pump has multiple impellers, allowing it to increase water pressure in a series—from one stage to the next—than a single impeller pump of the same size.

  
  


• 
  

  The head per stage is less, allowing for relatively smaller-sized impellers with tight tolerances, thus reducing leakage loss.

  
  


• 
  

  Multistage pumps also help reduce floor space. Additionally, due to smaller impeller diameters and tighter clearances, these pumps also require less motor horsepower resulting in higher performance and efficiency.

  
  


• 
  

  For pumps of the same discharge pressure output, an increase in the number of stages lowers noise levels than a single-stage pump.
