When you want to construct a well for your personal use, you will often need to make very good decisions regarding the type of pump you choose. This is one of the most critical parts of any well water systems, since it’s the part that conveys the water from the well to the house or other facility. The fact that there are many different types of pumps out there means that before you can make a decision on which one to get, you should have an idea of the broad categories of pumps you can get, as well as the pros and cons of using each. Once this is done, you will be in a better position to determine which one to get. The three broad categories of such pumps include:
Centrifugal pumps
This comprises a single pipe that is dipped into the water column. In order to use it, the pump itself sits on the ground level, and then produces suction that then pulls the water from the borehole or well. One of the major disadvantages of this type of pump is the fact that it can’t suction water to a level of more than 25 feet. This makes it only useful for wells that are shallow, such as water table wells. However, they are usually cheap to install, owing to their simple design and the fact that they only need to be placed around the well on the ground level in order for them to work.
Jet pumps
There are two types of pumps that can be used: the shallow well jet pumps and the deep well jet pumps. The shallow well jet pumps are similar to the centrifugal pumps in that they can only suction water for 25 feet, making them only useful for shallow wells. The shallow well jet pump is also installed on ground level, and is usually easier to use compared to the centrifugal pumps.
Deep well jet pumps are only useful for wells that have a water level more than 25 feet deep. They comprise two pipes that are dipped into the well; one that is used to suction the water and another that conveys water to operate the jet unit. In this case, the jet unit is installed within the borehole, normally below the level of the water.
Submersible pumps
As the name suggests, the submersible pumps are designed to be installed beneath the water level in a well. A small pump can fit a well that has a 3 inch diameter. The most popular pump for domestic use is the 4-inch submersible. They can be used for both shallow and deep wells, and are capable of pumping a lot of water from very deep wells. The choice of what submersible pump to use is often dictated by the depth of the well, as well as how much power one requires from the pump. Some of the most powerful are rated at around 75 horsepower.
