All EMAS handpump designs use glass marbles and standard PVC fittings and pipes as return valves. Different pump designs are available for high pressure, high quantity, hand-powered, pedal-powered, and windmill powered.
This movie shows how EMAS handpumps can be used in a well near the home, and how water can be pumped over a distance.
All movies are available in full length at http://vimeo.com/channels/emas. More info at http://www.emas-international.de
