Thus, before buying a pump, its best to list down all the uses of pumps that you may use it for. And hence, become able to purchase the right one for yourself.

Selection Criteria

It is recommended that while choosing the best pump for yourself, you take the system approach. Determine the pressure and the flow of the irrigation system is of the utmost importance. The system approach is about realizing that the conditions for the pump will constantly change. The pump may have to deal with heads and flows which are not generally expected. For such situations, it is best to gather all the information you can get about a pump before buying it.

The first thing to know is what conditions the pump will be dealing with mostly. And select the type of pump you need. Whether it is an end-suction pump, submersible pump, and multistage pump or vertical turbine pump. The pump should be able to give its highest efficiency on those operating conditions.

One of such factors is getting the net positive adequate suction pressure i.e. NPSHA verified. This will help in verifying whether it suits the application or not.  For your pump to be the jack of all, NPSHA should exceed the net positive suction head required i.e. NPSHR by at least 1 meter.
