Applications of Our Submersible Pump for Water

In many regions around the world, especially areas with limited surface water sources or inconsistent rainfall, well water pumps are essential for accessing groundwater. Borewell submersible pumps are specifically designed for this purpose—they remain fully submerged in water and are sealed to operate safely and efficiently under pressure. These pumps offer a reliable solution for drawing clean water from deep wells, making them ideal for agricultural, residential, and industrial use across diverse environments.

• Borewell Water Extraction (deep and shallow wells)
• Farm Irrigation & Drip Systems
• Water Supply for Buildings & Apartments
• Fire Protection Systems
• Sewage & Drainage Water Pumping
• Industrial Water Transfer

Factors to Consider while Buying Submersible Pumps

Choosing the right submersible pump is essential for achieving optimal performance and long-term reliability. Whether you’re investing in a borewell submersible pump for agricultural irrigation or a submersible pump for water supply in residential or industrial settings, the following factors should guide your selection:

Size of Borewell

The diameter of your borewell determines what size borewell submersible pump can be installed. It’s important to select a pump with an outer diameter smaller than the borewell casing. A mismatch can prevent proper installation and may damage the pump or the borewell walls.

Head

It is the height to which a submersible pump can lift the groundwater. A customer has to select the correct model of pump based upon the size of the house and the water table of the area where a pump will be installed. TDH (Total Dynamic Head) is calculated by adding the head length, pumping level, drop-pipe friction loss and check-valve friction. It is measured in feet or meters.

Delivery Size/Outlet

It is the diameter of the pipe that is used in order to discharge the water from the pump. This diameter is measured in inches or millimetres. It has to match the size of the pipe that is connected to the storage tank.

Discharge Rate

It is the volume of water (measured in litre/minute or hour) that can be pumped by a Borewell submersible pump per minute. A pump of large discharge capacity will be required in a large area.

Stage

All of our pumps come with an efficiency chart. Selecting the correct stages of a pump based on its head and motor rating is essential for maximum efficiency.

Cooling System

Submersible pumps are available with either water-filled or oil-filled motors. Water-filled motors use water as a coolant, which can be refilled as needed. Oil-filled motors are sealed and more economical but not refillable. The right choice depends on your operating environment and maintenance preferences.

Construction Material

A product’s durability depends largely upon the construction material. The pumps made of Noryl impeller and CI motor body are the most durable in the collection.

Advantages of Using a Submersible Pump

Investing in a high-quality submersible pump for water comes with several operational and efficiency benefits. Here are the key advantages:

• No Need for Priming: A major benefit of a submersible pump is that it remains completely submerged in the water source, eliminating the need for manual priming. This also reduces the risk of airlocks or dry runs that could otherwise damage the internal components of the pump.
• Better Efficiency: Submersible water pumps are designed to operate under the water surface, where fluid pressure assists in water movement. This allows them to draw water more efficiently, reducing energy consumption compared to surface pumps.
• Anytime Function: A borewell submersible pump allows for water extraction at any time, offering consistent supply without depending on water pressure or time constraints. This makes it ideal for residential buildings, farms, and commercial operations that require round-the-clock access.
• NRV (Non-Return Valve): All our submersible pumps are equipped with a Non-Return Valve (NRV) to prevent backflow, ensuring stable water pressure and protecting the motor. Available in both single-phase and three-phase options, our models are tailored to suit different power ratings and installation conditions.

Submersible pumps perform and last longer when they are installed correctly. We strongly recommend ensuring the pump is fully submerged in water inside the borewell. Operating a pump without adequate water coverage can lead to overheating and significantly reduce its durability.
