Meaning and Application of Openwell Submersible Pumps

In order to cater to the water needs of a big construction unit, it is essential to build multiple storage tanks for the facility. In such cases an additional reservoir or water tank is constructed at the bottom of the building. In order to pump water from this reservoir to the overhead tank an Open well submersible pump is required. Open well Submersible pump is a pump that is completely submerged in water and is sealed in an airtight fashion.

Open well submersible pumps find their application in:

  • Irrigation and gardening. 
  • Underground reservoirs/tanks in bungalows and apartments, sprinklers and fountains.
  • Hospitals, hostels, swimming pools, commercial complexes and hotels 

Mode of operation

Submersible pumps consist of an AC electric motor, impeller, diffuser, cable guard, submersible electric cable. Open well pumps are seated on the floor of an underground reservoir or tank and is connected to electrical supply for operation. A submersible pump lifts water to the desired level by converting the rotary energy of the impeller into kinetic energy of water. Water is sucked into the pump from where it is pushed/lifted by the rotation of the impeller through the diffuser.

Factors to keep in mind while selecting Open well submersible pumps :

1)Reservoir/Tank Size:

The user should look for a pump which fulfills the water circulation requirement. A general thumb rule is that the pump should be able to discharge 50% of tank volume per hour.


It is the height to which a pump can lift water. Depending on the size of the house and depth of the underground tank, the customer should select the best model. The reservoir depth where the pump is seated plus the height at which storage tank is located is the total head. It is measured in feet or metres.

3)Outlet/Delivery Size:

It is the diameter of the pipe through which water is ejected from the pump set. It should match the size of the pipe connected to our storage tanks. It is generally measured in Inches or mm.

4)Material of Construction:

This factor doesn’t affect the performance or application of pump but if one is looking for a product that has longer life, they should go for pumps with Noryl impeller and Stainless Steel motor body.

Advantages of an Open well Submersible Pump:

  1. Self- Priming: As these pumps are totally submerged in water, they do not need to be primed. It also avoids any air bubble in the pump set which may damage the inner lining of the pump.
  2. Enhanced Efficiency: As these pumps are submerged in the water source, it doesn’t need to spend a lot of power in extracting water from source. The pressure of water enables the movement of water in the pump.
  3. Location of fitment: Since the pump is situated below the ground, it is best suited for gardening and landscaping.
  4. Ease of installation: No requirement of new foundation for installation.
  5. Efficient cooling: Since the pump is submerged in the water it aids cooling of the motor also.
  6. No foot valve is required for this type of pump.

These pumps comes in both single and three phase models depending on the rating of the motor. Special care should be taken while installing the pump in the tank as, if it is not completely enclosed by water, it may cause overheating of the motor winding reducing the longevity of the product. Also the open well pump should be well seated on reservoir floor so that there is no vibration in the pump and it works properly.
