When you’re creating your lawn sprinkler system, choosing the right pump makes a big difference.
Homeowners, who have a well or have access to surface water such as lakes, ponds, or streams, can save money by using a pump to supply their lawn sprinkler system. In some cases a permit must be obtained before accessing a public water source, these permits are usually easy to obtain and are in most cases relatively inexpensive. The cost savings realized with using a pump system compared to the cost of using a municipal water source can be significant. These cost savings easily offset the initial investment of the pump, usually providing a payback of 1-2 years.
When selecting a pump, it is best to consult with an irrigation professional. There are several pump options to choose from depending on your water source. Here are four to consider.
- Centrifugal Pumps: A centrifugal pump is the most commonly used sprinkler irrigation pump. Centrifugal pumps are typically used to pump out of lakes, ponds, or streams. They are usually placed on shore and a suction pipe is run from the pump out into the water source. Centrifugal pumps must be primed (pump casing and suction line must be filled with water) before using.
- Submersible Pump: A submersible pump is placed into the water source. Submersible pumps are usually used in wells but can be placed in ponds and lakes (check local electrical codes before doing this) if a water induction sleeve is used. Submersible pumps do not need to be primed since the pump intake is submerged in the water.
- Self-Priming Centrifugal Pump: A self-priming centrifugal pump works the same as a standard centrifugal pump. The pump casing is larger and is designed to act as a tank to keep the pump impeller submerged. Despite what the name implies, the pump casing on self-priming pumps does need initial priming.
- Booster Pump: A booster pump is usually a centrifugal pump that is installed in a municipal water line. Booster pumps are used when the water pressure is very low to increase the pressure.
