- Borewell pumps lift deep water and naturally consume more electricity.
- Pumps generate less power in applications with lower head pressure in shallow water.
- Efficient motor and impeller design minimize electricity loss with high-quality energy saving pumps.
- The sizing of pumps is more important than selecting between borewell or openwell pumps.
Understanding How Borewell and Openwell Pumps Work
A borewell submersible pump is specifically used for deep borewell water extraction. It is placed in a narrow borehole and is kept completely underwater. These pumps are used at depths between 30 meters and above 300 meters, which means that they need more power in the motor to lift water to high heights.
An openwell submersible pump is used in shallow water wells like open wells, sumps, tanks, or reservoirs. The operating head of these pumps is relatively low, typically less than 15 to 20 meters. Compared to the higher-pressure and resistance demands of other types of pumps, they require less electricity to pump the same amount of water in shallow wells.

What Actually Determines Electricity Consumption?
Many people believe that there is always one type of pump that will use less electricity than the other type. As a matter of fact, power consumption depends on three major factors:
- Motor horsepower
- Total dynamic head
- Daily operating hours
A borewell pump operating at 100 meters would, of course, use more electricity than an openwell pump operating from a shallow sump. This difference is inevitable because of the energy needed to extract water from deeper wells.
But if the water source is deep, the submersible borewell is the most efficient option available. If the wrong pump is used for deep lifting applications, the motor can overheat, the water flow may become inadequate, and the electricity cost could increase over time.
That’s why it’s important to select the right energy saving pumps. When the pump is properly chosen, it is more efficient, puts less strain on the motor, and provides water delivery at a faster rate in less running time.
Why Borewell Pumps Can Be Energy Efficient?
Modern borewell submersible pumps are constructed using multi-stage impellers that build up the pressure as the water is raised. Such a design provides more efficient operation without a dramatic increase in electricity usage.
For instance, if the multi-stage borewell pump is properly matched at 60 meters depth, its electricity consumption is less than that of an undersized pump being used at an excessive depth. Energy loss is minimized by efficient motor winding, balanced impeller design, and quality construction in energy saving pumps.
Tormac Pumps produces borewell submersibles in different sizes, stainless steel, cast iron, and thermoplastic. If a pump is properly matched to the desired depth and flow rate, it will run efficiently for years, and electricity costs will be kept in check.
Where Openwell Pumps Have the Advantage
In shallow water applications, submersible pumps are typically more electricity efficient. They use less head pressure, and even a small motor can pump high flow with low energy usage.
These pumps are ideal for:
- Open wells
- Residential sump tanks
- Agricultural reservoirs
- Commercial water storage systems.
Also, these have lower installation complexity and shorter operating cycles, which further reduces electricity consumption. They are still one of the most dependable energy saving pumps when water is readily available in shallow depths.
Build Quality Also Affects Electricity Bills
The efficiency of the pump is not solely determined by the size of the motor. With poor-quality materials, worn impellers, corroded parts, and damaged bearings, pumps use more electricity over time.
The high-grade stainless steel construction is more resistant to corrosion caused by mineral-rich or saline water. Precision-engineered parts keep hydraulic efficiency and minimise internal friction. Long-lasting, efficient pumps are real energy saving pumps.
Tormac Pumps are built with quality materials and components that are designed to withstand the rigours of operation.

Final Thought
When it comes to electricity savings, there is no clear winner between borewell and openwell pumps. Openwell pumps work more efficiently in shallow water applications, and borewell pumps are most efficient and practical for deep groundwater extraction.
Reducing electric bills depends on selecting the appropriate pump type, motor sizing, and quality construction. A properly chosen pump ensures consistent flow, saves operating time, and remains energy efficient for years.
When selecting a pump for agriculture, residential, or industrial applications, the best investment is to pick the right model for the water depth and flow needed for a long time.
FAQs
- Which pump saves more electricity for agriculture: a borewell or an openwell?
- Openwell pumps are better at saving power when the water source is shallow, and borewell pumps are necessary when the water source is deep.
- Does a larger borewell pump motor use more electricity?
- Not always. Proper sizing, pump efficiency, and operating depth matter more than motor size alone.
- Can both pump types be used on the same property?
- Yes. Deep water extraction is done through borewell pumps, and water transfer and storage are done through openwell pumps.
