Where can a sand pump be used? Not everywhere. We do not recommend using it in environments with a high proportion of stones, such as when stones account for 30% or more. In such cases, we suggest using a dredger. For other environments, we can confidently say that it's safe to use, and we will design it based on the specific conditions. We have a variety of sand pumps, with the smaller ones capable of extracting 5-60 cubic meters per hour, and the larger ones can extract over 800 cubic meters. We design them according to the actual working environment, including the sand extraction depth and the distance for sand disposal. Generally, we use either a cutter suction dredger or a jet suction dredger; choose one based on your needs. The cutter suction dredger is more expensive but suitable for a wider range of environments, while the jet suction dredger is cheaper but only suitable for environments with sand collapse.
