LEWA GmbH, based in Leonberg, Germany, has developed the ecoflow LDC1 M910S hydraulic pump for use in a hydrogen electrolysis demonstrator system in Baden-Württemberg. The pump, with a hydraulic output of 0.2 kW and an Ex motor, can convey water at 30°C and 130 L/h against 40 bars. To withstand contact with the KOH solution, all components are made of stainless steel 316/316L and feature a PTFE sandwich diaphragm. The diaphragm, monitored by patented DPS technology, ensures uninterrupted operation of the electrolyzer, crucial for the 1-MWel system running since 2023. The hydrogen produced by this system will be fed into a new pipeline along the Neckar River in Stuttgart as part of the H2 GeNeSiS model region starting from 2026, showcasing the advancement of hydrogen technology in the region.
