The multiphase pumps developed by EDUR have been applied successfully for decades and optimized several applications. The most popular example for significant improvement of a process is the process of dissolved air flotation. By using EDUR technology in a flotation plant, gas can be directly fed to the conveyed medium via the intake line of the pump. Compared to conventional systems, plant components such as compressor, pressure vessel, complex control system and various valves are no longer required. This results in beneficial savings and simplification of the entire plant.

In addition, EDUR multiphase pumps have already proven to be a reliable pump solution in the field of rising markets and emerging technologies such as power-to-X or ozonation for the sterilization of drinking water. Thereby they enable applications with following requirements:
• Gases are to be dissolved in a liquid
• Media with high gas contents needs to be conveyed
• Process reliability has to be ensured when outgassing of the medium can occur

Key of the technological advantage is the EDUR-specific hydraulic design: Open impellers and bladed diffusers enable reliable and trouble-free operating conditions at gas contents of up to 30 percent without the occurrence of pulsation.

In order to further exploit the benefits of the EDUR multiphase technology, EDUR is increasing its cooperation with customers and research institutes for the developments and technical design of new plant concepts and technologies.
Frederike Holdhof, Managing Director of EDUR, is convinced: „For our proven multiphase technology, there are certainly many more (niche) applications we might not know about yet.”

Innovation partnerships and extensive testing of trial pumps in pilot plants create a win-win situation on both sides. Quite often, the collaboration between EDUR and its partners turn into successful long-term cooperation when scaling up technical solutions.
