MWMS Series 500 Sluice & Weir Insertion Gates
MWMS Series 500 Insertion Gates eliminates the high cost of a complete Gate replacement. MWMS Insertion Gates are designed to fit right into your existing Gate Frame.






During the preparation process pumps are shut down. The MWMS Channel Dam is installed and pumps restarted. The existing gates operator, stem, slide, seals, and the seat are removed. In many cases, due to prolonged exposure to gases, some of these components must be cut away. The frame is then carefully prepped, with special attention given to the inside verticals and ensuring the existing frame is properly squared.


The MWMS Series 500 Insertion Gate frame
is installed within the existing gate frame. It is carefully squared and securely bolted into place to ensure a tight, reliable seal between the existing frame structure and the insertion gate. A 1/8” rubber gasket is applied along the vertical sides of the existing gate frame to enhance the seal and prevent leakage. Once the insertion gate is inserted, aligned and firmly fastened, the upstream side of the gate is effectively sealed
