Abstract

The present invention pertains to the field of pump manufacturing and more precisely relates to hydraulic diaphragm pumps principally used for pumping a liquid from deep bore-holes. This invention can be used in the mining industry, in agriculture as well as in other industrial branches related to the exploitation of natural resources. The purpose of this invention is to improve the reliability as well as to simplify the assembling and disassembling process of a pump in a bore hole. To this end, the hydraulic drive of the pump and the pumping of the liquid are carried out through a single duct. This invention essentially relates to a hydraulic diaphragm pump comprising a hydraulic pulse generator (1) and a submerged part (3) which are connected by a duct (4). The submerged part (3) of the pump is divided into a discharge chamber (8), an intermediate chamber (9) and a suction chamber (13) which are serially connected together as well as to the surrounding medium through check valves (10, 12, 15). Resilient diaphragms (11, 14) are mounted between the discharge chamber and the suction chamber as well as between the intermediate chamber and the surrounding medium for transmitting the pressure to said chambers. The hydraulic pulse generator is further capable of periodically interrupting the tightness of the discharge chamber.
