The Access 1.2 pump is designed to benefit all people in need of affordable access to safe water.
The design promotes an understandable technology and the utilization of commonly available materials (adaptable to local supply) as well as the training of local technicians for its production and installation. The pump can quickly replace damaged hand pumps that are blocking access to viable boreholes.
In the Access design, the traditional O-ring has been replaced with a “proximity bushing” fabricated of a high tech resilient material with a very low coefficient of friction. The pump utilizes common, locally available PVC pipe for the suspension main and riser pipes thus avoiding the difficult logistics required in transporting the steel risers and pump rods required for traditional hand pumps. The cost of the Access 1.2 is much lower than traditional hand pumps, allowing maximum utilization of available financial resources.
The robust nature of the invention, combined with raw material accessibility and low cost, represents a viable opportunity for personal well ownership in areas of greatest need.
