<p>The invention relates to a pump device for improving the loading capacity of tank vehicles which are loaded by establishing partial pressure in the complete tank and drawing the liquid into the tank through a suction line. The solution is to equip the inlet end of the suction line with a hydraulically driven, submerged, centrifugal pump designed specifically for the application, to develop a pressure at the inlet end of the suction line.</p> |
