Key Takeaways
- Centrifugal pumps handle most general irrigation and water transfer jobs on a farm because they’re affordable, easy to service, and available in a wide range of sizes.
- Submersible pumps are the go to choice for deep wells, since they push water up from below instead of pulling it, which cuts down on priming problems.
- Vertical multistage pumps are built for jobs that need higher pressure over longer distances, like large sprinkler systems or pivot irrigation.
- Regenerative turbine pumps work well for low flow, high pressure tasks such as chemical injection or small scale spraying.
- Positive displacement pumps (gear and rotary vane types) are worth considering when you’re moving thicker fluids like fertilizers or liquid manure.
- Picking the wrong pump type usually costs more in energy and downtime than the pump itself, so matching pump design to water source and application matters more than brand loyalty.
- We support ag operations across the U.S. and Latin America with pumps from manufacturers like Grundfos, Berkeley, and Goulds, along with the motors and service work that keep them running.
Why Pump Selection Matters on the Farm
If you’ve ever had a pump fail during peak irrigation season, you already know how fast a small mechanical problem turns into a big financial one. Crops don’t wait for parts to ship.
We work with growers, distributors, and irrigation contractors across agricultural operations throughout North and South America, and the question we hear most often isn’t “which brand is best.” It’s “which pump actually fits what I’m trying to do.” Fair question. There’s no single best pump for agriculture, because the job changes depending on your water source, the distance you’re moving water, the pressure you need, and what’s actually in the water.
This guide breaks down the pump types that show up most often in agricultural settings, what each one does well, and where it tends to fall short. We’ll also flag a few things competitors’ guides usually skip, like how manufacturer selection and total dynamic head calculations actually affect your long term running costs.
Centrifugal Pumps: The Workhorse of Agricultural Water Systems
Centrifugal pumps show up on more farms than any other type, and for good reason. According to North Dakota State University Extension, horizontal centrifugal pumps are the most common type used in irrigation systems, largely because they cost less, need less maintenance, and are easier to inspect than vertical alternatives.
Here’s how they work, in plain terms. An impeller spins inside the pump casing, and that spinning motion throws water outward, converting rotational energy into pressure and flow. Simple mechanism, reliable results.
Where do centrifugal pumps make the most sense? Surface water sources mostly. Rivers, canals, ponds, and reservoirs that sit close to ground level. They’re a solid fit for general field irrigation, filling storage tanks, and moving water between points on the property.
One thing worth knowing: centrifugal pumps need to be primed before they’ll draw water. If the suction line loses its prime, the pump won’t move water until it’s refilled. That’s a minor annoyance for most operations, but it’s worth factoring in if your setup runs unattended for stretches of time.
We carry centrifugal pumps from manufacturers including Grundfos, Berkeley, and Goulds, sized for everything from small field irrigation to larger municipal-scale transfer jobs.
Submersible Pumps: Built for Wells and Deep Water Sources
Submersible pumps flip the whole concept around. Instead of sitting above the water and pulling it up, the entire pump unit goes down into the well or water source and pushes water to the surface.
That difference solves a real problem. No priming, no suction lift limitations, and less exposure to debris and clogging at the intake. For farms pulling water from deep wells, submersibles are often the only practical option once you’re past a certain depth.
They’re not without tradeoffs, though. Pulling a submersible pump for repair or replacement means physically removing it from the well, which takes more labor and equipment than servicing a surface-mounted unit. So while submersibles tend to be reliable, when something does go wrong, the fix takes longer.
Submersible pumps are common for stock watering systems, deep well irrigation, and drip irrigation setups where consistent, controlled flow matters. We supply submersible pumps built for these exact conditions, along with the pump service and repair support needed to keep them running through the season.
Vertical Multistage Pumps: When You Need More Pressure
Some jobs just need more push than a single-stage centrifugal pump can deliver. That’s where vertical multistage pumps come in.
These pumps stack multiple impellers in a single unit, and each stage adds pressure as water moves through it. The result is higher head pressure without needing a massive footprint. That makes them a strong fit for center pivot irrigation, long-distance water transfer, or any system where you’re fighting elevation change or friction loss across a lot of pipe.
Growers running large-scale sprinkler systems tend to lean toward multistage designs because undersizing pressure capacity is one of the most common (and expensive) irrigation mistakes. We’ve seen operations spend more fixing pressure problems after the fact than they would have spent sizing the pump correctly up front.
Not sure whether your system needs single-stage or multistage pressure? That’s usually a total dynamic head calculation, and it’s worth getting right before you buy. Our vertical multistage pumps come in a range of configurations depending on flow rate and pressure requirements.
Regenerative Turbine Pumps: Low Flow, High Pressure Jobs
Regenerative turbine pumps don’t get talked about as much, but they fill a real gap. They’re designed for applications that need relatively low flow combined with fairly high pressure, which is a combination centrifugal pumps generally struggle to hit efficiently.
In agricultural settings, that translates to jobs like chemical injection, small-scale spraying, or fertilizer application where precision matters more than volume. If you’ve got a system that needs steady, controlled pressure at a modest flow rate, a turbine pump is often a better fit than trying to force a centrifugal pump into that role.
We stock regenerative turbine pumps for growers who need this kind of precision application equipment.
Positive Displacement Pumps: Gear and Rotary Vane Types
Not everything a farm pumps is thin, clean water. Fertilizers, liquid manure, and certain chemical blends are thicker, and moving them efficiently calls for a different mechanism entirely.
Positive displacement pumps, including gear and rotary vane designs, move fluid by trapping a fixed volume and pushing it through the system mechanically. Unlike centrifugal pumps, their flow rate stays fairly consistent regardless of pressure changes downstream. That consistency matters when you’re metering fertilizer application or handling viscous fluids that would overwhelm a standard centrifugal design.
According to a technical overview from Gator Pump, positive displacement pumps such as piston and helical rotor types are typically used in irrigation systems that require high pressure operation with thicker or more variable fluids. That lines up with what we see in the field. Livestock operations and fertilizer application setups tend to reach for these pumps more than row crop growers do.
What Competitors Usually Leave Out: Sizing and Efficiency
Most articles on this topic stop at “here are the pump types.” They don’t get into what actually determines whether your pump saves you money or quietly drains your operating budget for years.
Pump sizing matters more than most growers realize. An oversized pump running below its efficiency curve wastes energy every single day it operates, and that cost adds up fast over an irrigation season. The USDA’s Natural Resources Conservation Service addresses this directly in its national pumping plant standard, which requires that pumping plant installations meet minimum energy use efficiency criteria and that new or replacement equipment be properly matched to the system’s actual flow and pressure needs, not just oversized for a margin of safety. You can review the full NRCS pumping plant conservation practice standard if you want the technical detail.
Here’s the practical version. Before you buy a pump, know your total dynamic head, your required flow rate, and your water source characteristics. Guess on any of those, and you’ll either underperform or overspend on energy for the life of the equipment. This is exactly the kind of sizing conversation our engineering team walks through with customers before recommending a specific model, whether that’s a Grundfos submersible for a deep well or a Berkeley centrifugal for surface irrigation.
Matching the Pump to the Job
So which pump is right for your operation? It depends on a handful of factors working together.
Start with your water source. Surface water usually points toward centrifugal pumps. Deep wells point toward submersibles. From there, look at pressure and distance requirements, since that’s what separates single-stage from multistage designs. And finally, consider what you’re actually pumping. Clean irrigation water behaves very differently than liquid fertilizer or manure, and the pump mechanism needs to match.
One more thing worth mentioning. Energy costs and reliability both improve when equipment is matched correctly the first time. We’d rather walk a customer through that sizing conversation upfront than sell the wrong pump and deal with a service call three months later.

Frequently Asked Questions
What is the most common type of pump used in agriculture?
Centrifugal pumps are the most widely used pump type in agricultural irrigation. They’re cost-effective, relatively simple to maintain, and well suited to surface water sources like ponds, canals, and rivers.
What’s the difference between a centrifugal pump and a submersible pump?
A centrifugal pump sits above the water source and uses suction to draw water up, while a submersible pump is placed directly in the water and pushes water to the surface. Submersibles avoid priming issues and are generally better suited to deep wells.
How do I know if I need a multistage pump instead of a single-stage pump?
If your system needs to move water over long distances, overcome significant elevation change, or maintain pressure across a large sprinkler or pivot system, a multistage pump is usually the better fit. Single-stage centrifugal pumps typically handle shorter runs and lower pressure requirements well.
Can positive displacement pumps handle irrigation water?
They can, but they’re generally better suited to thicker fluids like fertilizers or manure, where consistent flow regardless of pressure matters more than raw volume. For standard clean water irrigation, centrifugal or submersible pumps are usually more efficient and cost-effective.
Why does pump sizing matter so much for agricultural operations?
An improperly sized pump, especially an oversized one, wastes energy and increases operating costs over time. Sizing a pump correctly based on total dynamic head and required flow rate helps avoid unnecessary energy use and premature wear.
How often should agricultural pumps be serviced?
This varies by pump type, usage intensity, and water quality, but most agricultural pumps benefit from a seasonal inspection at minimum, with more frequent checks for submersible units in sediment-heavy wells. Regular maintenance catches small issues before they turn into costly downtime.
Does AMED-US supply pumps for both irrigation and chemical application?
Yes. We supply centrifugal, submersible, vertical multistage, regenerative turbine, and positive displacement pumps for a range of agricultural uses, from general field irrigation to fertilizer and chemical application, sourced from manufacturers including Grundfos, Berkeley, and Goulds.
