How to Choose a Submersible Pump
Submersible pumps are an essential tool for any homeowner or business owner who needs to move water from one place to another. They are used in a variety of applications, including:
- Draining flooded basements or crawl spaces
- Transferring water from one tank or reservoir to another
- Watering lawns and gardens
- Providing water for livestock
When choosing a submersible pump, there are several factors to consider, including:
The flow rate, which is measured in gallons per minute (GPM). The flow rate determines how much water the pump can move in a given amount of time. The head height, which is measured in feet. The head height determines how high the pump can lift water. The power source, which can be either AC or DC. AC pumps are typically more powerful than DC pumps, but they require a power outlet to operate. DC pumps can be operated using a battery, making them more portable. The size and weight of the pump. The size and weight of the pump will determine how easy it is to transport and install. The price of the pump. Submersible pumps can range in price from a few hundred dollars to several thousand dollars.
Once you have considered all of these factors, you can choose the submersible pump that is right for your needs.
1. Flow rate
The flow rate of a submersible pump is an important factor to consider when choosing a pump. The flow rate determines how much water the pump can move in a given amount of time. If you choose a pump with a flow rate that is too low, the pump will not be able to move enough water to meet your needs. Conversely, if you choose a pump with a flow rate that is too high, you will be paying for more power than you need.
To determine the flow rate that you need, you need to consider the following factors:
- The size of the area that you need to pump water from
- The height that you need to pump the water
- The type of water that you need to pump
Once you have considered these factors, you can use a flow rate calculator to determine the flow rate that you need.
Choosing the right flow rate for your submersible pump is essential for ensuring that you have a pump that can meet your needs. By following the tips above, you can choose the right pump for your application.
2. Head height
When choosing a submersible pump, it is important to consider the head height. The head height is the vertical distance that the pump must lift the water. It is important to choose a pump with a head height that is sufficient to reach the desired destination. If the head height is too low, the pump will not be able to lift the water to the desired height. Conversely, if the head height is too high, the pump will be working harder than necessary and may be more likely to fail.

Factors that affect head height: The head height of a submersible pump is affected by a number of factors, including the following:
- The length of the pipe
- The diameter of the pipe
- The number of bends in the pipe
- The viscosity of the liquid
-
How to calculate head height: The head height of a submersible pump can be calculated using the following formula:
Head height = (L + Kf f) (v^2 / (2 * g))
where:
- L is the length of the pipe in feet
- Kf is the friction loss factor
- f is the number of bends in the pipe
- v is the velocity of the liquid in feet per second
- g is the acceleration due to gravity in feet per second squared
- Choosing the right head height: When choosing a submersible pump, it is important to choose a pump with a head height that is sufficient to reach the desired destination. If the head height is too low, the pump will not be able to lift the water to the desired height. Conversely, if the head height is too high, the pump will be working harder than necessary and may be more likely to fail.
By following these tips, you can choose the right submersible pump for your needs.
3. Power source
When choosing a submersible pump, it is important to consider the power source. Submersible pumps can be powered by either AC or DC power. AC pumps are typically more powerful, but DC pumps are more portable.
- AC pumps are typically used for permanent installations, such as in a sump pump or a water well. They are more powerful than DC pumps, but they require a power outlet to operate.
- DC pumps are typically used for portable applications, such as in a boat or RV. They are less powerful than AC pumps, but they can be operated using a battery.
The power source that you choose will depend on your specific needs. If you need a powerful pump for a permanent installation, then an AC pump is a good choice. If you need a portable pump, then a DC pump is a good choice.
4. Size and weight
When choosing a submersible pump, it is important to consider the size and weight of the pump. The size and weight of the pump will affect how easy it is to transport and install. If you need to transport or install the pump yourself, it is important to choose a pump that is small and lightweight enough for you to handle.
The size and weight of a submersible pump will also affect the cost of the pump. Larger and heavier pumps are typically more expensive than smaller and lighter pumps. It is important to consider the cost of the pump when choosing a pump that is the right size and weight for your needs.
Here are some tips for choosing the right size and weight submersible pump for your needs:
- Consider the size of the area that you need to pump water from.
- Consider the height that you need to pump the water.
- Consider the type of water that you need to pump.
- Consider the portability of the pump.
- Consider the cost of the pump.
By considering these factors, you can choose the right size and weight submersible pump for your needs.
