<p>The present invention attempts to provide users of industrial explosives, particularly in the bank-blasting sector (quarries, mines, public works, etc.), with a useful, flexible and economical technical solution that solves the problem of removing water from bores. The invention describes the design and operation of a water-extraction pump based on the principle of pneumatic displacement, which uses, as an essential part, alternating intake and delivery cycles in order to provide the necessary operational performance level for the drainage process. Given its inventive design, with an exterior profile that has no appreciable projections, it will make it possible to minimize blockage problems as much as possible.</p> |
