Summary
This case study outlines the implementation of large axial propeller pumps by Sulzer for the Integrated Rhine Program (IRP) at Polder Rheinschanzinsel in Germany, aimed at enhancing flood protection. The project involves constructing a retention area to increase flood control capacity, providing an additional 6.2 million cubic meters of storage. The existing pump station will undergo reconstruction in two phases, with Sulzer pumps specifically selected for their ability to meet the required flow capacity of 20 cubic meters per second. The study details the challenges faced during the initial construction phase, where only three new pumps were installed to ensure continued flood protection. The solution includes the use of Sulzer's vertical submersible propeller pumps, which feature adjustable propeller blades and a full monitoring system. The benefits highlighted include reliable flood protection, energy efficiency, and long-term reliability for the end customer, as well as competitive advantages during the tendering process for contractors.
