Rotary weir
made of stainless steel

Rotary weirs are used for the rapid emptying of filter basins in water treatment plants. The weir is opened quickly so that all dirt particles floating on the water surface can be removed. To prevent the filter sand from being flushed out, the rotary weir has an additional protective seal on the side cheeks. This ensures a very good sealing performance even at low operating pressure. The extremely solid lever system is characterised by high stability and also guarantees a long-lasting sealing function.
