Effects of Low Voltage on Submersible Pumps and Solutions for Mitigation

Submersible borehole pumps operate under specific voltage requirements to function correctly. When the voltage supplied to the submersible pump is too low, it leads to a reduction in the pump’s performance and efficiency and can result in several issues. 

Here are some of the effects of low voltage on submersible pumps:

• 1. Reduced Performance: Low voltage causes a reduction in the motor’s speed, thus lowering the pump’s flow rate and output pressure. This means the submersible pump will not be able to deliver the required amount of water or at the required pressure, leading to a reduced pumping capacity.
• 2. Wear and Tear: As the submersible pump runs under low voltage, it will tend to overwork, causing overheating, which can lead to wear and tear of the pump’s components, notably the motor.
• 3. Increased Energy Consumption: When the voltage is low, submersible pumps require more power to run and maintain the desired flow rates, causing higher energy consumption and increasing electricity bills.
• 4. Maintenance Cost: More frequent maintenance is required for submersible pumps that frequently run under low voltage. It can compromise the lifespan of the pump, which means more frequent maintenance and ultimately higher maintenance cost.

In summary, running a submersible pump under low voltage can lead to reduced performance, wear and tear of pump components, increased energy consumption, and higher maintenance cost. This can result in a reduction in the pump’s lifespan and compromise the efficiency of the pumping system.

To mitigate against low voltage supply to submersible pumps, there are a few things that can be done if the power supply is too low for submersible pumps.

1. Firstly, you can consider using a pump that requires less power to operate.
2. Secondly, you can try decreasing the length of the power cable to reduce voltage drop.
3. Thirdly, if possible, you can try increasing the voltage supplied to the pump to improve its efficiency and performance. A voltage stabilizer, or Adjustable Voltage device can do this trick.
4. Finally, You can buy All Purpose Voltage Mediator – VRC360 from our Online Shop. This device can tell you the amount of voltage being supplied to your pump.

It’s important to note that without an adequate power supply, the pump may not function properly and could potentially lead to damage or failure.
