Pedrollo borehole pumps

Borehole testing

When first considering installing borehole pumps, testing the borehole for water yield is crucial to selecting the pump. The yield refers to the volume of water the aquifer one has drilled through or into is capable of providing to you. This is normally measured by the drilling contractor, who establishes the borehole yield and will record it on his certificate. The other test one needs to have done as fast as possible is the water analysis. One needs to ensure the water is safe for human consumption, free of toxins, heavy metals, E. coli, iron, magnesium, and excessive salinity. One may need to dose Chlorine or adjust pH levels; we recommend DOSECO Stepper Motor dosing pumps for this application. The outcomes of these tests will enable you to accurately determine the size of the pump, filtration, and treatment of the water you will extract for safe and viable consumption by humans, animals, or plants.

Submersible water pump

Pedrollo borehole pumps are well-renowned for high quality and ready availability. Our range of submersible water pumps and borehole pumps here in South Africa includes the Pedrollo 4 SR 1 and the other 4 SR models. Please follow the link at the bottom of the page to access pump data for our centrifugal water pumps. Dimensions, head, and flow curves for the range are a click away on the link below.

Water tanks in South Africa

When installing a borehole, it is inevitable that one will need a water tank to store the extracted water. The size of the tank is very important and is regulated not only by the pump’s capacity but also by usage. We recommend that the tank should be large enough to provide water for one week. So daily consumption multiplied by 7. This will enable one to secure a supply for a reasonable period should a breakdown or another technical fault render the deep-well pump unusable.

Solar water pump

Many people are very interested in the solar power route until they work out the numbers. The solar solution, while a really good idea in Africa, can be expensive. If one is remote and there is no power to the place where you want to establish the borehole, it is almost the only way to go. However, one must be aware of the pitfalls and the needs, especially here in South Africa, where a solar power system is like bread to a starving man. It will be stolen in moments if adequate security measures are not in place.

Pedrollo Borehole Water Systems

Water systems include the following:-

• The borehole pump and motor combination.
• The wellhead includes the baseplate that supports the electrical cable running to the pump motor, the support line that carries the pump’s weight as it hangs in the borehole, and the discharge bend and valve at the surface.
• The pump protection control panel.
• The water tank
• The pipe size and length required for the system.
• A booster pump to take water from the tank to homes, cattle troughs, irrigation sprays, etc.

One-piece Pedrollo monoblock pumps

Pedrollo monoblock pumps are very popular in areas where the borehole is not that deep, 30 to 60 meters from the surface. This range is supplied as a single unit with the pump and motor, unlike the Pedrollo 4SR 1 series, which has the pump separate from the motor.
