Boreholes can provide water for all kinds of applications including drinking water, washing and irrigation... Borehole users can extract up to 20,000 litres of water per day. Another great reason to start obtaining water from a borehole or well as opposed to mains water supply is that, in fact, it uses far less energy to extract water from a well or borehole than it does to obtain fresh, clean drinking water from other sources. Therefore, using a borehole not only costs you less but is also a lot healthier for our environment.
The combination of a hydraulic design with floating
impellers and the materials used allows the pump
to handle sand content of up to 150 g/m3 without
risk of blockage or premature wear.
