How to select a submersible pump

There are four important criteria for selection of your pump.

1. Bore well size : The diameter of the bore is the restricting Factor 
   e.g. If your bore size is 100mm then select 100mm Pumpset only.
2. Total head : Please Understand head as below : 
   Total head =A+B+ Draw 
   Down level + Seasonal 
   Variation in water level + 
   Frictional loses.
3. Discharge : The yielding of Bore is the criteria Important for pump selection. Only 75% of the Yield of the bore well should Be taken as rated 
   discharge of the pump.
   (Contact Your Bore well contractor to know the 
   yielding of bore)
4. MOTOR H.P. & Pump Stages : 
   For the above total head and For the above total head and 
   discharge select the motor & pumpset from the performance 
   table having maximum efficiency at duty point.
