Farm irrigation systems are a valuable asset for farmers seeking maximum crop yield.
To keep your irrigation system working efficiently and reduce plant and water waste, it is essential to make the right selection from available irrigation system pumps.
The pump must be purchased to fit the irrigation system based on system requirements and crop needs.
Finding the right farm irrigation system pumps involves understanding pump curves and how to read them.
What Is A Pump Curve?
A pump curve tells you how specific irrigation system pumps perform at different pressure settings as well as their flow rates.
When selecting pumps for farm irrigation systems, the best way to find one to satisfy your system needs is by looking at the pump curve.
Flow rate and pressure are essential factors that must be taken into account when searching for an irrigation pump.
It must push water through your irrigation system fast enough and at the right pressure so it reaches crops at the right pressure for correct, uniform application.
A pump curve can show you how well a pump will perform working at certain speeds and pressures yet avoid causing damage to the motor or other parts.
How Do You Read A Pump Curve?
To determine whether farm irrigation system pumps are suitable for your system, you need to know how to read a pump curve.
They are curve graphs that mark the performance of industrial irrigation system pumps at different pressure and flow rates.
These graphs typically include other essential information such as motor speed, horsepower, total dynamic head (suction), and other calculations that vary based on pressure and flow rate.
This documentation is usually made available by the manufacturer so you can research the curve and determine which specific type or model is most suitable for your irrigating needs.
How Do You Choose A Pump Based on Its Curve?
The important detail to keep in mind when choosing farm irrigation system pumps is that a pump can perform at various speeds to produce differing amounts of pressure and flow; however, the harder it works, the shorter its service life will be.
When researching performance curves to choose the best unit for different farm irrigation systems, the goal is to find one that delivers the right pressure and flow at the most ideal speed and load on the pump.
As such, the best option is usually a pump that can deliver the right pressure and flow at the mid-range in the performance curve.
The best efficiency point or BEP will always be more towards the center of the curve.
Summing It All Up
Since the data contained in these performance graphs may be challenging to understand, be sure to discuss your system type and irrigation requirements with your irrigation professional who can help you choose the right farm irrigation system pumps for your needs.
With the right pump, your irrigation system will run efficiently, your crops will receive the correct amount of water, and you can anticipate a bountiful harvest!
