GWE AQUASOLAR

Key Features

The German Water & Energy Group has a rich history in producing reliable hand pumps for rural water supply. They gained global recognition during the UN World Water Decade (1980-1990) for their high-quality hand pump systems, including SBF-INKAR, SBF-KARDIA®, and pb-MARK II, specially designed for rural water supply.

 

They offer a variety of corrosion-free riser pipe systems, such as SBF-KATUR® (PVC) and pb-schaub pipe (stainless steel).

 

Their continuous research and development efforts have led to top-notch water supply solutions.

 

The GWE aquasolar is a solar-powered deep well hand pump, bridging the gap between conventional hand pumps and solar-driven submersible motor pumps, which are crucial water sources in many developing countries.

This innovative system combines established pump technology with maintenance-free photovoltaic components, ensuring sustainable water access.
