Our foundry has decades of experience in producing wear parts for the dredging industry and is specialized in wear resistant materials. A range of compositions and hardness’s is available on request.

Our wear resistant materials are strong enough to withstand all your needs regarding mechanical and fluid forces.

The right choice for the impeller’s cast material depends on the dredge material. For dredging sand and clay we recommend high-chrome iron. When the dredging material is mostly composed of stone and rock (high impact) we recommend nickel-chrome steel.
