Choosing the Right Submersible Pump for Borewell

Borewell Pump Selection

UNICEF first brought the idea of bore well in India in order to support the vast agriculture sector of the country. Bore well makes groundwater easily accessible. The increased use of bore wells has replaced open pipes. In order to make bore well truly functional in all aspects, it is important to have a submersible pump. From the term itself, it can be understood that the pump will be submerged inside the water and it will be completely sealed. There are a lot of areas where we can see the wide use of submersible pumps such as houses, farm and irrigation, fire fighting systems, and many other industries.

When it comes to buying Borewell Submersible Pumps, there are a lot of factors that you need to follow. Size, head range, delivery pipe, motor cooling, water discharge rate, and so many important factors are there to consider choosing the best submersible pump for your bore well.

Below, we have shared some must-to-consider facts on to choose the best submersible pump:

How to choose the best submersible pump?

1. Choosing the right pump

Selecting the right pump is a critical task. When it comes to pump sizing, it can said that it is determined by the yield of the well and according to the requirements of the users. One should never install a pump with more capacity in comparison with the well. You should start with application type and expectation and then decide which type can best guide you. Apart from this, you should consider capacity and pipe size so that you can choose one that fits well and functions properly.

If the bore well is 6 inches, the most suitable submersible water pump diameters will be,

If the bore well is 4.5 inches, diameters of the submersible water pump will be,

  • 4-inch Submersible water pump
  • 3-inch Submersible water pump

2. Head range

It is one of the most misunderstood factors when it comes to how to select the best submersible pump for a bore well. A pump’s head should be the maximum height that the pump can have. If the pump is able to generate more pressure, it will be able to pump water higher as well as it will produce a higher head.

We have a simple quotation formula that you can follow to find your idea pump head range.

The formula is:

Bore well depth + distance between bore well to water tank * 140%= submersible pump head-range

Example: 150ft+40ft= 190ft*140%= 266ft (81cm)

3. Outlet size / Delivery pipe

In order to satisfy domestic requirements, we can see the use of 4.5 and 6 inches diaborewells. 4.5 is known as the most commonly used one for domestic purposes. When it comes to higher yield for agriculture or building purposes, we can see the use of 6 inches bore wells.

In the case of outlet / delivery size, it will be the diameter of the pipe via which the water will be pushed through the pump. It must match the size of the pipe that is directly connected with the storage tanks. You will see that its measurements are generally taken in mm or inches.

4. Water discharge rate

The discharge rate stands for how much water the pump is able to move per hour or per minute. In order to remove clogged rainwater, you can choose a pump with 250- 500 gallons per hour. In the case of flooded land, you will require a pump with a high water discharge capacity such as 1000-2000 gallons per hour.

5. Motor cooling

Submersible pumps generally come with two types of motors such as oil-filled and water-filled motors. In the case of the water-filled motor, the cooling agent is water and it can be filled overnight. On the other hand, the oil cannot be replenished and it increases the change of pump damage.

Buying a submersible pump for a bore well is a complicated task. But hope this guide will help you in solving the complications. If you are planning to buy a cheaper one, you can go for oil-filled motors connected pumps. But if you want an expensive and durable one, you should choose a submersible pump that comes with a water-filled motor.
