A look at LEAP technology, (Low Energy Air Pumps), which controls air flow through air operated diaphragm pumps with a fundamentally different principle. Pump manufacturer Tapflo claims that this technology shows efficiency improvements at all air pressures.

The improvements are most marked at low air pressures. Now instead of starting at more than one bar with a possible tendency to stall at such pressures, a pump will start at as little as 0.2 bar and operate more smoothly and more quietly as well.

This technology is promoted as part of a revolution. What do AODD pump users think?
