              Revolutionary pump drive and coupling system cuts costs

              Voith has partnered with Fuglesangs Subsea to develop an advanced pump drive and coupling system, leading to outstanding reliability and huge costs savings. By integrating a Voith torque converter into the pump on the sea floor, electrical variable frequency drives on the topside are no longer required for speed control.

              Applications

              Gas turbine starters

              High breakaway torque and superior acceleration power for a reliable start-up of gas turbines.

              Subsea pumps

              In this application, a Voith torque converter is integrated inside the pump, which is installed on the seabed. Apart from an electrical supply line, the system does not require any other supply lines. It paves the way for improved profitability against the background of decreasing flow rates at existing wells and increasing distances at expansion wells. Operators benefit significantly from this solution as investment costs are reduced by up to 70 percent. This stems from the fact that heavy and space-intensive equipment no longer has to be integrated on one platform, but that a compact unit is installed on the seabed.

                A new solution for speed control

                Ideal for compressors and pumps, the new VECO-Drive offers the most efficient speed control. A low voltage variable frequency drive (VFD) controls the servomotors and a superimposed planetary gear adjusts the output speed for the driven machine.
                 

                With additional power supplied by the servo motor to the drive train, a smaller main motor can be used, reducing your capital expenditures. The servomotors also function as starters, protecting the electrical grid against high inrush currents.

                Efficiency and speed: VECO-Drive’s key benefits

                • high output speed for compressors and pumps
                • peak component efficiency of up to 97%
