The Barmesa brand submersible pumps can be used for many different applications. The Barmesa design incorporates state-of-the-art technology using 21st century manufacturing techniques.

Many industries use Barmesa pumps for effluent, sump and other purposes.

Barmesa makes excellent quality pumps for commercial and industrial use that can solve different types of problems. These pumps can be operated in dry conditions without damaging the motor or seals, which makes them ideal for a variety of applications such as construction, fire protection and irrigation among others.

Municipalities often choose Barmesa pumps in the water treatment plants, but today we will discuss pumps in wells to demonstrate their application.

Shallow Well Pumps

Well depth is a key factor in choosing a pump. Shallow well pumps use centrifugal force for wells that are no more than 25 feet deep. These wells are beneficial for power savings and easy construction and installation.

Centrifugal pumps also last a long time without requiring servicing. As a caveat, wells deeper than 25 feet will require a different pump due to loss of pressure at the faucet.

Shallow wells are prone to running dry, as a decline of just 5 feet in the water table (for example, during the spring months in some parts of the U.S.A.) can lead to the water level dropping below the pump’s intake. As many shallow wells are constructed on top of bedrock, they cannot be dug out any deeper. In this case, it is advisable to dig more than one well and employ multiple shallow well pumps to ensure a constant flow of water.

Barmesa Deep Well Pumps

Wells drilled from 25 to 110 feet in depth should use a Barmesa deep well pump with a more forceful ‘jet pump.’ Deep well pumps employ impellers, diffusers and a jet injector to force water upwards long distances in contrast to the centrifugal shallow well pumps. Pump suction, power, discharge pressure and speed are dramatically increased using this type of pump.

Choosing a quality deep well pump  is essential as they are prone to their own problems. For example, the pipe, the foot valve and the strainer can become clogged. If this happens, the deep well pump can pump sand or mud through your pipes instead of water.

In cold climates, pipes sometimes freeze entirely, cutting off all water flow. In such climates, alternative well pumps, such as submersible well pumps, can provide a better option.

Barmesa Submersible Well Pumps

These pumps, also called deep well submersible pumps, sit at the bottom of the well, and rather than pulling water out of the well, they force it upwards through a pipe. Used in wells deeper than 110 feet, these pumps are hermetically sealed and airtight to avoid leakage, which leads to pump damage and water contamination.

A common issue with submersible pumps is their inaccessibility. Since it is located sometimes 300 feet below ground, wiring faults can be difficult to detect and fix. This is yet another reason to choose a high-quality pump and wiring when installing a deep well pump.

Price Concerns

Shallow well jet pumps are less expensive to replace than submersible models. Deep well jet pumps are priced somewhat between the other two types, but submersible pumps are considered more reliable than jet pumps. Moreover, submersible pumps reach pressure 30 times faster than jet pumps and run more quietly, which can be a major consideration in some projects.

Also consider the cost. Intuitively, a dug well of only 25 feet in depth is cheaper than a 150-foot deep well project. Prices for drilling a well are dependent on the foot depth of the bore and type of earth material being drilled (sand, solid rock or clay).

Drilling costs are usually $15-$30 per foot. This amounts to $375-$750 for 25-feet, $1,500-$3,000 for 100-feet and $6,000-$12,000 for pumps needed at 400 feet. In some cases, with difficult geological conditions, costs can reach $30-$50 per foot or more.

Additional costs associated with a well including wiring, piping and the well control panel system.


Drilling is a complicated and sometimes confusing process, but knowing the ground type you will be drilling, the depth required and the type of pump needed for different depths are the first steps in choosing the correct pump and creating an estimated budget for your project.

Barmesa makes quality pumps for just about any job and budget.
