How to Choose a 100 Meter Submersible Pump?

How to choose a 100 meter submersible pump is a question we all wonder. To get water from 100 meters depth, there are several factors you need to consider.

First of all, you need to determine the amount of water you needand the speed at which the water is pumped out. You will also need to consider technical details such as the distance and elevation difference over which the water will be pumped.

100 Meter Submersible Pump Selection and Calculation

Determine your water needs: First, you need to determine how much water you need on a daily or hourly basis. This may vary depending on factors such as the purpose of water use, family size or irrigation purpose.
Determine the water output rate requirement: You must determine how much water the submersible pump should output per minute or hour. This will be in liters/minute or liters/hour, which refers to the performance characteristics of the pump.

Calculate the depth and distance factors: Determine the depth of the source from which you want to take the water (100 meters) and the distance of the water from the surface where the pump will be placed. Also take into account the difference in elevation from the source to the outlet.

Check pump performance: Check the technical specifications of submersible pumps to determine which ones are suitable for the water output speed, depth and distance you have specified.

Submersible pump selection: Considering the above steps, choose the submersible pump that suits your needs. The main factors to consider are the pump’s flow rate (water output speed), maximum pressure (depth and distance), energy consumption and durability.

Making calculations: To check whether the submersible pump is compatible with your requirements, check the specifications and performance tables provided by the pump manufacturer. These tables indicate the pump’s water output speed and pressure values for different depths and distances.

100 Meter Submersible Pump Sample Calculation

Let’s make a selection to illustrate a simple submersible pump selection. We assume that we have 100 meters well depth, 200 meters horizontal distance after the well and 10 meters elevation difference.

The information we need to calculate a submersible pump:

1. Total depth 100 meters
2. Horizontal distance 200 meters
3. Level difference 10 meters

Desired hourly water quantity: 6 tons

Determining the maximum pressure: To calculate the maximum pressure we will use the elevation difference and the horizontal distance. The total elevation difference from the well to the water outlet point is calculated.

Total height difference = Depth + Elevation difference + Horizontal Distance

Total height difference = 100 meters + 10 meters = 110 meters

Horizontal Distance = 200 / 10 = 20 mss

Total Pressure 130 mss, so the pressure of the pump we will choose should be 13 bar

In addition, if the pump will supply water to a system that requires extra pressure such as dripping or sprinkling, we need to add the pressure required for them to this 13 bar.

For example, you can choose a submersible pump with a water output rate of 6000 liters/hour (about 100 liters/minute) and a pressure of 130 meters.

Accordingly, the most suitable product for our calculations; Impo SK 412/25 Deep Well Submersible Pump Motor 7.5 Hp 150 mss 16.99 m³/h

What are the Features to Look for in a 100 Meter Submersible Pump?

Choosing a submersible pump involves several factors that need to be considered to find a pump that suits your needs and application area. Here are the important steps to consider when choosing a submersible pump:

Flow and Head: Determine the flow and head requirements of the submersible pump. Flow rate is the amount of water pumped per hour (or minute). Head is how high the pump can pump the water.

Electrical Power and Voltage: Determine the electrical power required for the pump and the appropriate voltage. You should choose a pump suitable for the electrical infrastructure of your application area.

Suction and Discharge Dimensions: The suction and discharge dimensions of the pump determine the availability with suitable hoses and connections for the application. Therefore, consider the inlet and outlet dimensions of the pump.

Ease of Use: The submersible pump should be easy to use and maintain. Choose a model that is portable and practical to use.

Protection Features: The submersible pump must have protection features against overheating, overload and drying out. These features make the pump safer and longer lasting.

Durability and Material: The durability of the material used in the construction of the pump is important. Long-lasting and quality materials such as stainless steel should be preferred.

Automatic Control: Some submersible pumps can be equipped with water level sensors and operate automatically. This is an important feature to automatically react to changes in water level and save energy.

Brand and Quality: Choose a reliable and recognized pump brand. Quality submersible pumps offer more reliable performance and require less maintenance.

Warranty and Service: The warranty period and service facilities of the pump is also an important factor. Choosing a manufacturer that offers easy service in case of possible malfunctions or problems is important for long-term satisfaction.

Cost and Budget: Finally, consider your budget and the cost of the pump. Instead of going for the cheapest option, opt for a pump that is affordable and suits your needs.

By following these steps, you can make the right decision about choosing a 100 meter submersible pump and choose a pump that suits your needs

However, in real applications, submersible pump selection is a more complex process and various other technical factors must be considered. Submersible pump selection requires an engineering assessment including the required flow rate, pressure, depth, pipelines, water characteristics and many other factors.

Therefore, I recommend that you seek the help of an engineer or specialist for a precise and accurate pump selection. They can guide you in choosing the best submersible pump for your specific needs and application.
