Borehole pumps are a class of submersible pumps used to control water and liquid supply.
A borehole is a narrow shaft drilled vertically into
the ground which has dimensions that are
slightly larger than the borehole pump that is lowered into the borehole.
This depends upon the depth of the borehole
to ground level and then the distance from the
ground level to the final end point e.g.
where the water tank is sited. The further the distance,
the higher the pressure requirements of the borehole
pump to prevent the water from trickling out.
Submersible borehole pumps are a type of
submersible pump. They are centrifugal pumps
driven by a submersible motor.
As they usually draw in the fluid directly without a suction line,
they must constantly be submerged in the fluid handled.
Starter borehole pumps can run for up to 24 hours.
However, your everyday borehole pump will run between 6 & 8 hours.
It is not good for your borehole pump to run continuously.
If you run electrical pumps continuously,
your utility bill will skyrocket.
Put simply the borehole should be as deep as
is required to reach the aquifer (water bearing rock).
The average depth of a borehole is between 80m and
120m but this can be less as well as significantly more.
