Hey there! As a supplier of Irrigation Well Pump, I've gotten tons of questions about the difference between submersible and surface irrigation well pumps. So, I thought I'd break it down for you in this blog post.
Let's start with the basics. An irrigation well pump is a crucial piece of equipment for getting water from a well to your fields or gardens. It makes sure that your plants get the water they need to grow healthy and strong. Now, the two main types we're going to talk about are submersible and surface pumps, and they each have their own unique features and uses.
Submersible Irrigation Well Pumps
A submersible pump is designed to be fully submerged in water. That's right, it goes right down into the well! This design has several advantages. First off, because it's in the water, it doesn't have to work as hard to draw the water up. The pressure from the water around it helps push the water into the pump, which means it can be more energy - efficient.
Another great thing about submersible pumps is that they're quiet. Since they're underwater, the noise they make is muffled. This is a big plus if you have your well near your home or a quiet area. You won't have to deal with a loud, annoying pump running all the time.
Submersible pumps are also less likely to get air in the system. Air in the pump can cause problems like cavitation, which can damage the pump over time. Being underwater helps prevent this from happening.


However, submersible pumps do have some drawbacks. They're a bit more expensive to install. You need to have the right equipment to lower the pump into the well, and you might need a professional to do it. Also, if something goes wrong with the pump, it can be a hassle to get it out of the well for repairs.
Surface Irrigation Well Pumps
On the other hand, surface pumps are installed above ground. They're usually easier and cheaper to install. You don't need to worry about lowering a heavy pump into a well. All you need to do is connect it to the well using a suction pipe.
Surface pumps are also more accessible for maintenance. If there's a problem, you can easily get to the pump and fix it. You don't have to go through the trouble of pulling it out of a well.
But surface pumps have their limitations. They rely on suction to draw water from the well. This means they have a limited suction lift. Generally, they can only lift water from a well that's about 25 feet deep. If your well is deeper than that, a surface pump might not be able to get the water out effectively.
They're also noisier than submersible pumps. Since they're above ground, all the noise they make is out in the open. If you're sensitive to noise, this could be a problem.
Performance and Efficiency
When it comes to performance, submersible pumps usually have an edge. They can handle higher flow rates and pressures. This makes them a great choice for large - scale irrigation projects where you need to move a lot of water quickly.
Surface pumps, on the other hand, are better suited for smaller irrigation jobs. They can still get the job done, but they might not be as powerful as submersible pumps.
In terms of efficiency, submersible pumps are often more energy - efficient. As I mentioned earlier, the water pressure around the pump helps it work more effectively. Surface pumps have to work harder to draw the water up, which can use more energy.
Cost Considerations
The initial cost of a submersible pump is higher. You have to pay for the pump itself, which is usually more expensive than a surface pump, and then the installation costs. But over time, the energy savings from a submersible pump can offset the higher initial cost.
Surface pumps are cheaper upfront. They're less expensive to buy, and the installation is simpler and cheaper. However, if you're using a surface pump for a long - term, large - scale project, the higher energy costs could add up.
When to Choose Each Type
If you have a deep well (more than 25 feet), a submersible pump is probably your best bet. It can handle the depth and get the water out effectively. It's also a good choice if you need a high - flow, high - pressure system for large - scale irrigation.
If you have a shallow well (less than 25 feet) and a small - scale irrigation project, a surface pump might be the way to go. It's cheaper to install and maintain, and it can still meet your water needs.
Other Types of Pumps in the Mix
While we're on the topic of pumps, it's worth mentioning a couple of other types that you might come across. The Progressive Cavity Slurry Pump is designed to handle thick, viscous fluids. It's great for applications where you need to move slurries or other heavy - duty fluids.
Another type is the Fecal Pump. As the name suggests, it's used for pumping fecal matter and other sewage - related materials. These pumps are built to be durable and resistant to clogging.
Conclusion
So, there you have it! The main differences between submersible and surface irrigation well pumps. Each type has its own pros and cons, and the right choice depends on your specific needs. Whether you have a small garden or a large farm, there's a pump out there that's perfect for you.
