Understanding a pump station’s flow and pressure capability
Pump stations have a lot of moving parts and can seem complicated, but they serve a very simple purpose, to deliver the right pressure at the desired flow to make irrigation systems perform at their best!
Understanding the flow and pressure capability of a pump station is simple if you take a few moments to understand the basic performance curve.
Take a look at this CLP Pump station performance curve.
- The blue shaded area represents the optimum operating range.
- The purple line represents the desired operating pressure boost. The “boost” value is the difference between how much pressure you already have and how much you need.
- The points where the desired pressure boost line intersects the edges of the shaded blue area determine the safe operating flow range for the station.
- In this case the desired pressure boost is 50 psi and the optimum flow range is 75 to 270 gpm.
It’s that easy!
