What is Borehole Water Pump
Borehole pumps are a type of submersible centrifugal pump of multistage design which can be submerged at large depths. They are typically designed to fit in narrow holes called boreholes which are drilled to extract water from water tables or aquifers deep below ground.

How much does it cost to drill a borehole in South Africa?
around R 600 a metre
The average drilling cost is around R 600 a metre, according to the Borehole Water Association of Southern Africa (BWA). Once drilling is done and groundwater has been found, there’s another outlay for installing a pump – about R25 000 to R30 000 – and then about R 12 000 for the laboratory water tests.
What pumps are used in boreholes?
Borehole pumps are a type of submersible centrifugal pump of multistage design which can be submerged at large depths. They are typically designed to fit in narrow holes called boreholes which are drilled to extract water from water tables or aquifers deep below ground.
How do you size a borehole pump?
As a rule of thumb, the nominal pump diameter should be the same as the borehole diameter. If the borehole is too big there’s a risk that the lack of velocity past the motor will cause the water to stand still in the borehole and potentially overheat the motor.
