Compressor pumps and submersible pumps are two distinct types of pumps used for various water pumping applications. While both serve the purpose of moving water, they differ significantly in their operation, installation, performance, and more.
The compressor pumps rely on compressed air to create pressure, which moves the water and allows it to be pumped. They operate by creating a vacuum to draw water into the pump and then using compressed air to force the water upward and out.
In contrast, submersible pumps are fully submerged in the fluid they are pumping and convert rotary energy into pressure energy to push the water to the surface.
It’s easier to make good choices when you understand the difference between compressors and submersible pumps.
We’ll explain the differences between compressors and submersible pumps so you can make the right choice.
Compressor vs Submersible Pumps: The Differences
There are several differences between compressors and submersible pumps in these categories:
- 1. Operation
- 2. Installation
- 3. Performance
- 4. Maintenance
- 5. Noise
- 6. Efficiency
- 7. Cost
- 8. Durability
- 9. Water Quality
Let’s examine the differences in more detail.
1. Operation
You’ll be amazed at how effortlessly a submersible pump operates. It seamlessly converts rotary energy into pressure energy, all while staying cool in the surrounding fluid.
Unlike compressor pumps, submersible pumps don’t require priming since they fully submerge in the fluid they are pumping.
As the pump’s motor spins, it drives a series of impellers that draw in and push out the fluid, generating pressure that moves the fluid to the surface. Compressor pumps, on the other hand, rely on compressed air to force water upward and out of the pump.
They create a vacuum in the suction pipe, drawing water into the pump, and then use compressed air to generate the pressure needed to move the water.
This process makes compressor pumps more complex than submersible pumps, which can lead to more maintenance and repairs over time.
However, compressor pumps are better suited for certain applications, such as pumping water from deep wells or in areas with low water pressure.
2. Installation
The installation process for compressor pumps and submersible pumps differs significantly.
Compressor pumps are typically installed above ground, away from the water source. They require a source of power, like an electric motor or a gas engine.
The pump is connected to the water source through a suction pipe or hose. This setup allows the compressor pump to draw water into the pump for further compression and upward movement.
The above-ground installation provides easier access for maintenance or repairs since the pump is readily accessible.
On the other hand, submersible pumps are installed inside the fluid they are pumping, such as in a well or a sump pit. They are designed to be fully submerged in water or fluid. Submersible pumps are connected to the power supply through a waterproof cable that runs from the pump to the surface.
It is crucial to ensure proper sealing to prevent water from entering the motor. The installation of submersible pumps requires specific well or pit configurations and may involve more complex setup procedures compared to compressor pumps.
Due to their above-ground installation, compressor pumps offer more flexibility in terms of installation location.
They can be placed in various positions above the ground, allowing for easier access during maintenance or repair operations.
On the other hand, submersible pumps are limited to being installed inside the fluid they are pumping. This means installation requires specific well or pit structures to accommodate the pump, which can involve more planning and construction.
3. Performance
In regards to the performance of compressor vs submersible pumps, it’s important to look at factors such as discharge rates and flow rates.
Compressor pumps have lower discharge rates compared to submersible pumps, which means they may need help to provide high flow rates. This can be a disadvantage in applications requiring a large volume of water, as the compressor pump may not be able to keep up.
On the other hand, submersible pumps are known for their high efficiency and ability to handle solids or wastewater. They can provide higher flow rates, making them suitable for applications requiring a large volume of water.
To better understand the differences in performance between compressor and submersible pumps, consider the following table:
| Performance Factors | Compressor Pumps | Submersible Pumps |
| Discharge Rates | Lower | Higher |
| Flow Rates | Lower | Higher |
| Handling Solids/Wastewater | Limited | High-Efficiency |
| Suitability for Deep Wells | Limited | Suitable |
As you can see, submersible pumps outperform compressor pumps regarding discharge rates, flow rates, handling solids/wastewater, and suitability for deep wells.
However, compressor pumps may still be suitable for certain applications where the water yield is low or in areas with loose soil. When choosing between compressors and submersible pumps, you must consider your specific needs and requirements to select the best option for your water system.
4. Maintenance
Maintaining your pump is crucial for ensuring its longevity and preventing costly repairs down the line. When comparing compressor pumps to submersible pumps, it’s important to note that the former typically require more frequent maintenance due to their higher number of moving parts.
On the other hand, submersible pumps are more challenging to access for maintenance or repairs since they are located inside the fluid being pumped. The pump may need to be lifted or pulled out of the well or pit if maintenance is required.
Here are four key points to keep in mind when maintaining your compressor or submersible pump:
- Compressor pumps require periodic inspection and adjustment of their priming mechanism. This ensures that the pump can maintain its prime and continue to function properly.
- Submersible pumps may require less frequent maintenance due to their simpler design, but when maintenance is required, it can be more difficult and time-consuming.
- Both pumps require regular cleaning to prevent clogs and debris buildup. This is especially important for submersible pumps, as they are more susceptible to clogging due to their location.
- It’s important to follow the manufacturer’s recommended maintenance schedule and procedures to ensure that your pump is functioning at its best. Failure to do so can result in decreased efficiency and costly repairs.
Overall, both compressor and submersible pumps require regular maintenance to ensure their longevity and optimal performance.
While the specific maintenance needs may differ, following a regular maintenance schedule and proper procedures can help prevent costly repairs and keep your pump working efficiently.
5. Noise
Compressor pumps can produce a considerable amount of noise during operation, especially if they need to be properly isolated or equipped with noise-reducing features. This can be a significant consideration, particularly in residential settings where quieter operation is desired.
Excessive noise can be a nuisance to those living near the pump and can even be a health hazard, causing hearing damage or sleep disturbances.
On the other hand, submersible pumps operate silently since they’re submerged in the fluid. This can be a significant advantage, especially in residential settings or applications where noise reduction is important.
Submersible pumps are ideal for environments where noise reduction is a critical factor, such as in residential areas or in applications where noise pollution is a concern.
6. Efficiency
To maximize efficiency, you should consider the pressure of the surrounding fluid when selecting a pump. Submersible pumps have a distinct advantage over compressor pumps in this aspect.
The surrounding fluid pressure helps the submersible pump to push water to the surface with less energy input. This means that submersible pumps are generally more efficient compared to compressor pumps.
7. Cost
Compressor pumps tend to be more affordable upfront compared to submersible pumps. This is because compressor pumps typically have a simpler design and construction.
They consist of a pump unit and a separate power source, such as an electric motor or a gasoline engine. Installing a compressor pump usually involves connecting the pump to water via a suction pipe or hose. The simpler design and installation process contribute to a lower initial cost for compressor pumps.
On the other hand, submersible pumps generally require specialized construction and materials to withstand being submerged in water or other fluids.
They are designed to operate efficiently and reliably in submerged conditions, often requiring more robust and corrosion-resistant components.
The need for waterproof seals, specialized cables, and protective casings adds to the cost of submersible pumps. These factors make submersible pumps more expensive upfront compared to compressor pumps.
8. Durability
If you’re seeking a pump that can withstand harsh environmental conditions and last for a long time, you’ll want to consider the durability of your options.
Regarding durability, submersible pumps are designed to be more robust than compressor pumps.
Here are three reasons why:
- Protection from environmental factors: Submersible pumps are designed to be submerged in water, which means they are protected from environmental factors such as dust, debris, and extreme temperatures. This protection increases their lifespan and reduces maintenance costs.
- Heavy-duty construction: Submersible pumps are constructed with heavy-duty materials that can withstand the wear and tear of constant use.
The motor and other components are sealed and protected from moisture, which reduces the risk of damage and extends their life.
- Lower risk of mechanical failure: Compressor pumps can be prone to mechanical failure due to the high pressure and temperature they operate under.
On the other hand, submersible pumps operate under lower pressure and temperature, reducing the risk of mechanical failure and increasing their reliability.
