postheadericon All You Need to Know About a Borehole Pump

A borehole is a shaft of varying depth, diameter and orientation (vertical or horizontal) dug into the ground for the purpose of extracting a liquid or gas. For instance, boreholes are dug to extract oil and gases for fuel from underground. However, the most common use of boreholes is to extract water for domestic consumption, irrigation or industrial use.

Underground water is more pure water compared to surface and runoff water, since it gets filtered as it seeps through rocks and beds of earth. Furthermore, it contains more minerals, which contribute to good health. Obtaining water from a borehole can be a daunting task but finding the appropriate paraphernalia will bring generous results.

Boreholes can be so shallow that a bucket can be lowered on a rope to draw water. Boreholes of this depth are commonly known as wells and they are popular in areas where the water table is near the surface. However, most boreholes are very deep, with some running several thousand feet into the ground. To obtain water from such boreholes, a powerful borehole pump is required.

Borehole pumps come in various designs and capacities. Jet pumps and submersible pumps are among the most popularly used pumps in boreholes. Jet pumps are installed on the ground surface above the borehole. A network of pipes is introduced to the water in the borehole while another pipe work connects the pump to a reservoir where water is held or distributed. The pump draws water from the borehole through suction and pumps it into the reservoir. One disadvantage of such a borehole pump is that it exhibits pump cavitation, which is attributed to the great elevation distance between the surface of water and the pump.

Submersible pumps, on the other hand, are immersed in the water at the bottom of the borehole. They work on a pushing principle where they pump water from the bottom upwards. Since the whole pump assembly is immersed in water, these electric pumps are sealed and airtight to prevent entry of water into the pump’s mechanical devices. The electric cables are also insulated to prevent any interferences with the flow of current or short circuits. When buying a borehole pump for industrial or domestic use, it is advisable to consult with borehole experts to determine the most appropriate pump.
