What size pump do I need to achieve a particular size coverage?

If you are going to be using a pump to supply the water to your sprinkler, it is important to get the right size pump for the intended performance level.

Each sprinkler comes with a performance chart. Use this to find out the pressure and flow rate needed to use that sprinkler to water the area you wish to cover.

Then, find the performance chart provided on the pump you’re interested in to find the option that will produce the required flow at adequate pressure to match the requirements of your sprinkler and the distance you wish to cover with water.

Don’t forget to account for friction loss and elevation changes between the pump and where the sprinkler will be sitting.
