The shaft seal is the component that seals the engine shaft as it enters the pump case. Carbon/ceramic is the cheapest seal material there is and is a strong indication that your pump is designed to pump water only. Cheap trash pumps usually utilize small diameter carbon/ ceramic shaft seals. The agitator water jet system is necessary to deliver kinetic energy (energy of motion) to the sediment to take it from a solid state rendering it a fluid slurry.Ĭheap trash pumps are not designed to withstand abrasion or shock. Flexibility: Dredges can be used on different applications and challenging projects.First of all, a self priming pump alone is not very effective in removing sediment.Easy achievment of naval register certifications: our dredges are built according to the RINA regulations (Italian Naval Register), and their small structure has permitted rapid certifi cation from the naval registers of competence.Limited draught: dredges have a limited draught, also suitable to work in shallow water conditions.High working depth with small floating dimensions: Depth up to 100m.
Easy to handle: our dredges are designed to be handled by an operator with a minimum experience of naval equipment.Easy transportation: Hulls are built in disassembled modules for easy transportation.Easy and quick assambly: Our dredges are specifically designed and manufactured for easy assembly, both on the ground or in the water, also in difficult conditions.Thanks to the innovative technology Dragflow dredges and dredging equipment have proven to be a reliable solution in dredging projects all over the world.
