To move water from the lowest to the highest level or to raise it to the needed static pressure so that it may be used to irrigate fields via piping systems, irrigation pumps are necessary (sprinkling). Centrifugal, submersible, jet, and propeller pumps are just a few of the many types of pumps available. They can be used for everything from watering your garden to preventing wildfires in large-scale agribusiness. Electric or gas-powered pumps can pull water from a municipal supply or a natural source, including a lake or pond.
Right Irrigation Pump Selection
This pump’s size is determined by comparing the pressure (psi) at which water enters the system with the flow (gph) and force (feet of head) required by the watering system itself and then selecting the motor that will most effectively connect the two.
Those looking to construct a simple irrigation system suitable with water sources can find a variety of tutorials online. If your irrigation needs are more complicated, you may want to consider hiring a professional irrigation company. Pumping curves are a good starting place for selecting the pump in the middle of the equation.
Pump manufacturers publish pump curves in the foot of the head and psi to show how well their pumps function at various pressures and flows.
The curvature of a pump changes depending on the design of the pump. The pump’s efficiency peaks at a specific discharge and head combination and gradually decreases as the outflow rate rises.
Selecting the most efficient pump at the stream rate and pressure level required for your system is the primary goal.
Pumps powered by electric motors typically run at 1750 and 3500 rpm (12 to 2 hp). Compared to models driven at 3500 rpm, models operated at 1750 rpm have lower heads but higher discharge.
Types of Irrigation Pumps
For residential irrigation, centrifugal pumps are the most prevalent since they can draw on water sources from municipal water supplies to creeks and offer stable flow rates underneath a wide range of situations. Sucking in water must be flooded with water or primed before working. Centrifugal pumps for irrigation are demonstrated in great detail in the video above.
Submersible Pumps are often utilised in pressure raising applications since they can operate underwater. They are more efficient than they are versatile. No priming is required, and they work pretty quietly.
Jet Pumps are an excellent choice in settings where water levels fluctuate because of their submerged components and terrestrial design. Water lift is achieved by using a jet pump, which directs water into an intake. Unlike reciprocating pumps, which need to be primed, jet pumps do not.
Large volumes of water can be moved at low head using propeller pumps. Irrigation pumps with propellers are among the tiniest.
- Self-priming pumps don’t need to be manually primed, which may be a time-consuming and messy procedure that requires putting buckets of water into the motor and pipe.
- It’s possible to engage a booster pump when a low flow of water is detected using a flow switch, which can raise the water pressure to a safe level.
- Using a Timer, you can save money by watering your lawn at off-peak times. They can be configured to work while you’re at work or on vacation to save you time and inconvenience.
- There are many pressure switches, but the most common are designed to help keep pumps operating at their optimum efficiency by switching them on and off as needed.
- Pumps with high levels of corrosion resistance are more likely to last for many years after installation. Submersible pumps must have this characteristic to function correctly.
