Borehole Water Pump
Borehole Water Pump extract ground water from deep wells for home, agricultural, construction or commercial use.
There is a wide range of Borehole Water Pump, ranging from 3- 10 metres borehole pumps depending on what you want the m for. Three metres are mostly for residential, 4 metres pumps for regular users, then 6 to 10 metres pumps for heavy duty and mining applications.
Borehole Water Pumps come in three options of plastic, stainless steel or cast iron.
How does a borehole pump work?
A complete Borehole Water Pump consists of two parts that works together to pump water from a borehole to the surface.
The first part is a borehole pump, also known as the wet end, it has several stages that moves the water to the surface.
To move the pump, you need a borehole motor, that fits your specific pump. Different combinations of pumps and motors will give you different delivery curves. The motor also comes standard with a control box, specific to the size and make of motor.
Because borehole pumps come into direct contact with minerals in the soil, they are made of corrosion resistant materials. Borehole pumps consist of two main components: a foot part that houses the pumping mechanism and contacts the water that is to be pumped, and the head part, which serves as the weight-bearing portion and the outlet for the water.
What do you need to install Borehole Water Pump?
One still needs a base plate, borehole casings, submersible cables, safety rope and HDPE pipes to complete the borehole installation.
Optionally a water storage tank might also be required, to store water in case there is a power failure, so a person will still have water in the tank.
Of course, as you would expect, most borehole drilling companies supply all of the above mentioned.
Borehole Recharge Rate
Bear in mind that the depth of the water is an average measurement. The water level in a Borehole Water Pump will drop as it is pumped out of the borehole and rise as it is recharged (more on borehole recharge here). The borehole’s recharge rate should also be considered when selecting a pump, particularly where the application involves de-watering.
Each borehole will be drilled to a specific diameter. The diameter of the borehole will dictate the diameter of the submersible Borehole Water Pump that will need to be used in the borehole. Here, you will have to do a bit of a cost balancing act, because a pump with a small diameter will generally need to have more stages or impellers than a pump with a larger diameter to achieve the same output.
