Suction lift and the number of sprinkler heads operating at any given time are the key determining factors in selecting a sprinkler pump. Determine the number of heads and multiply them by 3. The sum (gpm requirement) should be compared with the pump performance chart found on the pump carton.11 Feb 2016
How do I choose an irrigation water pump?
- the type of water source.
- the required pumping flow rate (determined by the irrigation system requirements)
- total suction head (lift from the water surface to pump intake)
- total dynamic head (total pressure supplied by the pump)
How big of a pump do I need for drip irrigation?
To calculate flow rate you will want to add up the number of emitting devices in your system, (i.e. 100 button drippers) and multiply by the emitters' flow rate (i.e. 1 GPH). 100 drippers x 1 GPH = 100 GPH required in the system.3 Dec 2020

How much water do I need for irrigation?
Calculating Water Use To provide your lawn with one inch of water takes a little over half a gallon per square foot (0.623 gallon to be more exact). That means that every 10'x10' area will require over 62 gallons of water.
