Choosing the Right Submersible Pump for Water Lifting up to 70 Meters

In this article, we will guide you through the process of selecting the appropriate submersible pump for lifting water to a height of 70 meters. Determining the right pump size involves several key factors, including the Total Dynamic Head (TDH), flow rate, and the power source available. We will also explore alternative power options for scenarios where electricity is not accessible.

Key Considerations

To ensure the selection of a proper submersible pump, you need to consider the Total Dynamic Head (TDH), required flow rate, and the power source. Here's a step-by-step guide to help you make an informed decision:

Total Dynamic Head (TDH)

The Total Dynamic Head (TDH) depends on the total height the pump needs to lift the water, which includes the vertical lift and any additional friction losses in pipes or fittings. If we only consider the vertical lift, which is the core calculation for this scenario, the TDH is 70 meters. This parameter is crucial for determining the pump's specifications.

Flow Rate

Determining the required flow rate, whether in liters per hour or gallons per minute, is essential. This information helps in selecting a pump with the appropriate capacity to meet your water lifting needs.

Pump Size and Specifications

Submersible pumps are typically rated by their flow rate (liters per minute or gallons per minute) and head (the maximum height they can lift water). For a 70-meter lift, a pump capable of handling at least 70 meters of head is generally recommended. It's essential to select a pump that matches both your flow rate and the required head.

Recommended Pump Size

Pump Type:

A submersible pump designed for deep well applications or a borehole pump would be appropriate for your needs. These pumps are specifically engineered to handle the pressure and flow required for deep water extraction.

Flow Rate:

For example, if you require a flow rate of 1000 liters per hour (approximately 17 liters per minute), you should look for a pump that can provide this flow at a head of 70 meters.

Power Source Options

If you do not have access to electricity, several alternative power sources are available to power your submersible pump. Here are some options to consider:

Solar-Powered Pumps

Solar Submersible Pumps are a great choice for areas without a reliable power source. These pumps can be powered by solar panels, making them ideal for remote applications. Ensure that the solar system can provide enough power to run the pump at the required flow rate and head. Proper energy calculations are crucial to avoid underperformance.

Wind-Powered Pumps

Wind Turbines can also be used to power submersible pumps, especially in areas with consistent wind. Wind turbines generate electricity that powers the pump, making it a viable solution for remote locations. However, wind conditions must be favorable for this setup to be effective.

Manual Pumps

A Manual Hand Pump is a practical option if the volume of water needed is not substantial. This alternative requires manual effort and is a good choice for small-scale applications. However, it may not be suitable for large-scale water lifting.

Diesel or Gasoline-Powered Pumps

If an immediate power source is required, diesel or gasoline-powered portable engine-driven pumps are a viable solution. These pumps offer flexibility and can be easily moved to different locations. However, they come with the added requirement of regular maintenance and fuel supplies.

Summary

In summary, choosing the right submersible pump for a 70-meter lift involves selecting a pump with the appropriate head and flow rate. Solar-powered submersible pumps are recommended for locations without electricity, but wind, manual, and engine-driven pumps can also be considered based on specific needs and circumstances.

Always consult with a pump specialist to ensure that you select the right pump for your specific application and requirements. This advice will help you maximize the efficiency and performance of your pump, ensuring reliable water lifting even in challenging environments.
