The request
The request consists in End Suction pumps type KDN 80-250/250/ AW/BQQV or KDN 65-315/XXX/A/BQQV depending on project data (flow and pressure) connected to a hydraulic motor by a CLAW COUPLING, supplied with special mechanical seal type BQQV (Carbon / silicon Carbide/ silicon Carbide/ Viton) suitable for pumping chemical solutions. The pump directs the liquid solution to the bottom of the borehole, the continuous operation of the pump causes the scrubber to flow between the column and the casing. In some cases, with high flow capacities can be used two pumps in parallel.
The pumps must be installed on special machines for drilling wells and are painted in blue to meet with the colour brand. Using this model of pumps instead of screw or piston pumps has an advantage regarding installation (space and cost) and maintenance.
