Advantages of Multi Stage Pumps

The advantages of multistage pumps are

  1. The Head per stage is less.  This results in reduced leakage loss.
  2. The pump can operate at lower speeds.
  3. The efficiency of the pump will increase.  
  4. The impeller size can be small as the head per stage is less.
  5. Multistage pumps can pump water to greater heights than single stage pumps.
