We can help companies, regions and communities reduce the cost of transporting clean water and mitigate the damaging effects of climate change.

Company History

Phil Selwyn invents and develops a modern alternative to the traditional zero energy ram pump. By using a new flexible rubber valve, (venturi valve) with a profile similar to an aircraft wing, it allows for a more compact in-line design.

The first of many patents are granted for the Papa Pump.

The first metal version of the Papa Pump is sold.

The design is refined and a new engineering composite material is used for the main pump components. The non-corrosive construction gives the pump a much longer life, a huge weight reduction and better efficiency compared to its Victorian designed counterparts. The new composite pump hits the market.

The Seradisc Filter is produced - a water filter with a larger surface area, fully adjustable to conditions, a unique design to reduce vortexing and a polymer construction which will not degrade. The result is a more efficient water extraction and filtration.

Another important company development at this time is the Venturo Pump, the world's first large scale ram pump aimed at utility markets which require high volume water transfer - eg for off-grid plantations. The Venturo can pump up to 30,000m³ per day using nothing more than the power of moving water.
