Can You Use a Submersible Pump in a Shallow Well?

The use of a submersible pump in a shallow well is a matter of consideration, especially if you are looking for a cost-effective and efficient solution for your water extraction needs. In this article, we will discuss whether a submersible pump can be used in a shallow well, the key factors to consider, and the types of submersible pumps available for such applications.

General Considerations

Yes, you can use a submersible pump in a shallow well, provided that the water column is deep enough to prevent the pump from touching the bottom and allowing for sufficient water volume to avoid running dry. However, shallow well pumps are often much cheaper than submersible pumps and come with their own storage tanks. When using a submersible pump, you will need to install a storage tank, pressure valve, and a start switch for the pump.

Types of Submersible Pumps for Shallow Wells

For shallow well applications, there are several types of submersible pumps that you can consider:

Standard Submersible Pumps

These are the most common type of submersible pumps used in shallow wells. They are designed to be fully submersed in water and are typically fitted with a motor and impeller assembly to extract water from the well. Standard submersible pumps are suitable for clean, fresh water and can be used for subsurface applications.

Bore Pumps with Flow Tubes

Bore pumps are specifically designed for shallow well applications where water is not directly over the motor. In these pumps, a flow tube is fitted around the motor to ensure that the water passes the motor and effectively cools it during operation. This design helps prevent overheating and extends the life of the pump.

Comparing Open Well and Deep Well Pumps

Submersible pumps come in different configurations, including open well and deep well pumps:

Open Well Submersible Pumps

These pumps are designed for horizontal installation and are typically shorter than deep well pumps. They are suitable for wells where the casing diameter is sufficient to allow the pump to be placed horizontally. Open well submersible pumps are often used in scenarios where the water table is closer to the surface.

Deep Well Submersible Pumps

Deep well submersible pumps are vertical and long, designed for wells that are deeper and have a narrower casing. These pumps are often used in industrial applications where the water table is deeper and the well is more extensive.

Usage and Maintenance

Submersible pumps can be a reliable solution for shallow well applications, provided that the water is clean and fresh. Selecting the right pump for your duty is crucial. While Laxmi Hydraulics, a well-known manufacturer in India, offers good quality submersible pumps, it is essential to maintain these pumps regularly. Frequent changes of bushes (seals) are necessary to ensure the pump's longevity and efficient operation.

When installing and using a submersible pump, it is important to consider the water quality, well depth, and the specific requirements of your project. Proper selection and maintenance can significantly enhance the performance and reliability of the pump, making it a cost-effective solution for your water extraction needs.
