Applications
Essential drainage solution for marine showers, sinks, bathtubs, and any below-waterline fixtures that cannot drain by gravity. The LSU 600 automatically removes drain water and pumps it to holding tanks or overboard discharge, preventing water accumulation in bilges and maintaining dry, safe vessel interiors. The automatic float switch ensures hands-free operation.
Ideal for head compartments, galley sinks, shower stalls, and wet heads on sailboats, powerboats, and yachts. The multiple inlet connections allow simultaneous drainage from shower, sink, and other fixtures into a single pump system. The built-in filter prevents debris from damaging the pump, while the transparent cover allows quick visual inspection without disassembly.
