KSB is about to launch its long-tried Etaline line pump, which uses a new, high-efficiency motor. It is understood that using the Pump Drive developed by KSB, its heating and cooling system, can save 65% of the energy costs for operating the pump. Due to KSB's Dynamic Pressure Setting Compensation Technology (DFS), the drive is able to save more energy equivalent to part-load conditions than a variable speed system and maintain a constant setting. For 15 kW motors, energy costs can be set at 1,000 euros per year for different settings. The other optional module interconnects the two drives, allowing the user to run two combined pumps with sequential control. Given that the two motors can operate simultaneously in a dual pump configuration, the Etaline Z is indeed a two-unit unit that offers a high level of redundancy. The easy-to-read backlit display shows PumpDrive's permanent actual speed and function allowing the user to adjust the speed and other local set points. PI controllers, and standard signals for digital and analog inputs and outputs, supporting all typical pump control modes. Motor protection as standard. KSB is the only supplier that offers this motor package variable. KSB is the only supplier that offers this motorized speed control system installed pump that drives up to 45kW. Modulation is as easy as a constant pump.
