Abstract

In the article, we aim to demonstrate the use of progression cavity pumps in the exploitation of geothermal energy from deep boreholes. The progression cavity pumps presented in the article are the kind generally used to extract oil from deep boreholes. The former provide a very large amount of power while overcoming the pressure elevations of extraction. Their capacity is relatively small, up to 0,005 m3/s. It is expedient to use such pumps during the exploitation of geothermal energy when we do not have sufficiently powerful centrifugal pumps at our disposal and when the exploitation of thermal water is intended for the purposes of health tourism.
