Basin bottom check valve FLO-PLUG® 2

membranehydraulicpolypropylene

FLO-PLUG® 2 was engineered and patented by NORHAM in 2007 to provide a professional solution for preventing the mechanical damage caused to the bottoms of tanks when groundwater and gas rises particularly when the tank is empty. With no moving parts, the tank floor protection device, FLO-PLUG® 2 is comprised of: A “hat-shaped” body, with holes drilled all over its periphery, made from PP Homopolymer, with a UV-resistant coating. and an EPDM membrane that covers it. Thanks to the materials chosen for its manufacture, the FLO-PLUG® 2 device is highly resistant to: pressure, corrosion, mechanical stress, UV light, sewage, and withstands temperatures ranging from -40°C to + 90°C. FLO-PLUG® 2 offers a feed-through flow rate of 5,000 l/h (for concrete basins/tanks - 4000l/h for geomembrane basins) for a pressure loss (groundwater pressure or gas pressure needed for opening the valve) of 60 mbar (60 mm head).
