How to Choose the Perfect Submersible Pump For You?

Submersible Pump

What are submersible water pumps?

The submersible water pump is a mechanical device that transforms fluid underground from a low-pressure to a high-pressure environment. This pump’s key advantage is that it prevents cavitation in the pump’s components. A submersible pump, unlike jet pumps, pushes fluid to the surface, creating a vacuum by relying on atmospheric pressure. As a result, submersible pumps outperform jet pumps in terms of efficiency.

Submersible water pumps have grown quite popular and in demand in recent years. These submersible pumps come in diversifying styles, each with its unique set of features.

Here comes the most exciting question, how to select one?

So to help you out with this!

The top 7 things to keep in mind while selecting the best submersible water pumps are:

1. Type of water

The most crucial thing to know when purchasing a submersible pump is the sort of water you intend to pump. The specifications of submersible pumps vary depending on the type of water and location –

  • Clean water

If you want to collect clean water, such as rain, and pump it for storage, a narrow submersible pump with a maximum grain diameter of 5mm is the best option. You should also consider how much soil will be pumped along with the water.

  • Dirty water 

If the water you want to pump contains a lot of dirt, you’ll need a dirty water pump. These pumps should be able to perform properly even in the presence of mud and dirt particles. These pumps are suitable for cleaning sewage and septic systems. One of the most crucial aspects to consider when purchasing a submersible pump for filthy water is grain size. The ideal gain diameter is between 10 and 20 mm.

  • Well Water 

These pumps are frequently used to transfer water from household plumbing systems. Because not all pumps are suitable for very deep groundwater pumping, submersible pumps are utilized to extract water from deep wells.

  • Ponds Water 

To operate a fountain or manage a running stream, a submersible pump is required. The pumps can be installed directly. Pumps for freshwater and saltwater are available in a variety of configurations.

2. Discharge Head

Submersible pumps are generally used to pump water from a low place to a high place. This is the height of the drain. Used to determine if the water is reaching the intended level. If you want to pump water from the rain barrel to another container, the drain height will be significantly lower. However, if you want to pump water far above the ground, you will need a higher discharge head.

3. Cooling system

Underwater motors are filled with a coolant such as oil or water. In a water-filled engine, the coolant is water and can be refilled repeatedly. However, with oil-filled engines, the lack of coolant increases the likelihood of engine wear and damage. For this reason, water-filled pumps are more expensive than oil-filled pumps.

4. Suction Depth

As water is pumped, its water level drops. The suction set may not be completely covered with water. This situation will allow the air to get in and stop the pump from working, such a condition is called suction depth. 

5. Back-up System 

Submersible pumps operate on voltage. Therefore, it is very important to get a pump with a backup power supply to avoid severe flooding and cleaning processes that rely heavily on electric pumps. A pump with a battery power it and allows it to withstand prolonged emergencies.

6. Bore-well Size

Bore-well size is the size of the hole for placing the submersible and is often called the borehole. After checking the diameter of the pump, you can dig the well. The bigger the pump, the bigger the well, and the same for the small pump.

 7. Material and pump selection

The material does not affect the performance or application of the pump. But if you are looking for a pump that has a long operating life, choose a pump with a Noryl impeller and a CI motor body. The first thing to consider is the brand of the water pump. The engine or motor will also tell you the quality of the pump. Before buying a submersible pump, do the necessary research and read customer reviews online.
