A Borehole Pump is used to extract water from a borehole and knowing the best Submersible Pump to use for your borehole in Zimbabwe in very important.
How do they work?
Because borehole pumps come into direct contact with minerals in the soil, they are typically made of corrosion-resistant materials. |

Where are they used?
Borehole pumps are used in a variety of fields including irrigation, municipal water supply, construction, mining, and industry.Types Of Pumps
- Submersible Borehole Pumps: These pumps have to be fully submerged in the water in order to draw in the water and pump it to a particular location. A submersible pump is typically used where there is ample water to cover it, and this type is often used for groundwater supply, drainage, domestic water supply, and pumping towards a filter. They are not often used in boreholes, because boreholes tend to be long and narrow. However, where there are underground water resources that provide easy access for a submersible pump, they can be used very effectively.
- Borehole Water Pumps: The natural shape of a borehole is long and narrow. A drill is used to penetrate deep into the soil and to locate a water source. Then a pump that fits the size of the borehole must be used to pump out the water. Often, a test pump is installed first in order to determine the yield and the amount of power needed for the pump, and only after that can the appropriate, and permanent, borehole water pumps are installed. Borehole water pumps are relatively easy to maintain and quite cheap to run, and a reliable pump can provide you with many years of hassle-free water!

Factors To Consider When Selecting A Borehole Pump:
- Available power source
- Total dynamic head
- Available Power Source
The first and most basic factor to consider when selecting a borehole pump is to determine the available power source 220V Single phase of 380V Three-phase if you intend to use a 380V 3Phase pump make sure that your 380V three-phase power source as three live lines a neutral line and earth available.
Total Dynamic Head:
The total dynamic head of the water system must also be considered when determining the size of the borehole pump to be installed.The total dynamic head determines the various head losses that the pump must overcome.
Total Dynamic Head = Elevation Head + Friction Head Loss + Pressure Head
Elevation Head:
Elevation head is the vertical distance which the water must be pumped, in other words, the depth of the borehole.In situations where the water after reaching the top of the borehole must still be pumped up an incline to reach the top of a hill or fill a water tank on a stand remember to add these additional heights to the Elevation head.
Elevation Head = Depth of Borehole + Tank Height (If Applicable) + Any Additional Vertical Inclines (if Applicable)
Friction Head Loss
Friction head loss is the loss of pressure due to the flow of water through pipe and fittings. Friction head loss can be reduced by using a larger diameter pipe or by changing piping materials.Friction head loss can also be compensated for by calculating the friction head loss using the following information and an Online Friction Head Loss Calculator:
- Flow Rate in (m3/hr) – m3/hr = L/hour ÷ 1000 or m3/hr = (L/Min x 60) ÷ 1000
- Pipe Diameter in (mm)2
- Pipe Length in (m)
- Pipe Material
After entering all information on the online calculator click the calculate button and enter the pipe friction loss result in (m) into the Total Dynamic Head Formula in place of the Friction Head loss.
Pressure Head:
Pressure head is the maximum operating pressure of the water system converted from pressure (bar) to (meters of head)(m)This is applicable only to water systems that get their pressure directly from the borehole pump, not for Water tank systems.
If you are pumping into a water tank or dam the pressure head in the Total dynamic head formula will be 0m.
If you need 3bar of pressure for irrigation when the irrigation system is connected directly from the borehole pump, simply add 30m to cover the Pressure head.
Or for other required pressures add 10m of pressure head to the Total Dynamic Head formula for every 1 bar of pressure required.
Finally, it is important to consider the borehole output capacity as tested by the borehole driller so as not to have too large a pump and over-pump the borehole causing the pump to dry run.
