Abstract
Pneumatic pump, especially for use in large boreholes, for drawing water, characterized in that an inflatable cylindrical hollow body is provided, of elastic material, hermetically closed at both ends by solid plugs and equipped with a riser tube, flexible, which runs in axial direction and which passes through the hermetically sealed plugs and because in each of the plugs a new through hole is provided, a valve governable by the internal pressure of the inflatable hollow body being mounted in the bore of a plug.
