Industry Award

The design and dimensional tolerances of this transitional pump discharge necessary to provide hydraulic compliance with the Engineers needs made this a very challenging project. The expected golf ball size debris flying through the pump discharge required special attention and approvals for the lining and coating process. Unlike the conventional challenges, the overall geometry with the ancillaries required made these pump discharges a landmark project.
