Engineering Overview & Construction
The Flounder Flat Silt Scourer is purpose-engineered for flat-bottomed box culverts and large diameter storm mains. Its ultra-wide bottom skid keeps it pinned to the channel floor, directing horizontal high-energy fan jets directly under heavy bed silt.
Standard Design Features
- ā High-thrust rear driving jets provide maximum tractive power and rapid silt/debris transport.
- ā Precision-machined from heat-treated hardened stainless steel for extreme abrasive wear life.
- ā Replaceable ceramic/carbide orifice inserts configured for optimal jet geometry and flow efficiency.
- ā Streamlined hydrodynamic body prevents wedging and hang-ups on pipeline offsets and joints.
Flounder Flat Silt Scourer Flushing Nozzle
Low-profile weighted flat bottom scourer designed for culverts, large storm pipes, and flat box drains to blast accumulated heavy bed load.
