Selecting the right irrigation pump for your project can affect your timeline, budget and the longevity and performance of the irrigation system. The experts at the Central Pump Hotline have the knowledge and resources to help you select a pump that is well suited for the job, allowing you to move on to your next job with confidence.
The following tips will help you get started.
TIP #1 – Know your GPM.
Gallons Per Minute (GPM) can be easily determined by multiplying the number of sprinkler heads in your largest zone by the sprinkler manufacturer’s specified required GPM for maximum efficiency. If you have multiple types of sprinkler heads, choose the type with the highest GPM required.
TIP #2 – Know what power supply you have available.
You will need a pump that can run efficiently off of the power available at the application site, without sustaining damage. Will your pump be electrical or gas driven? What voltage and phase do you have available? Collecting this information early will save time and frustration later and can also be helpful when determining which pump start relay is best for the system.
TIP #3 – Know your water quality and accessibility.Â
Accessibility, proximity to the irrigation system, available pressure or required lift, and water quality are all important considerations in pump sizing and selection. Here are some things to consider:
- How far away is the water source – long pipe runs may require increased performance to compensate for friction losses.
- Is it pressurized – domestic water sources or gravity fed systems may have some incoming pressure to consider.
- Is the water dirty or filled with debris – filtration can help to avoid damage to the pump and may also create additional friction losses.
- Is the water source easily accessible – will you need any special fittings, hoses, or valves to access the water
Avoid frustration and hassle by gathering the info you need in order to select the correct pump for the job.
