Where can a sand pump be used? Not everywhere, first off, we do not recommend using it in environments with a high concentration of stones, such as when stones make up 30% of the composition. No issues there, but above that threshold, we suggest opting for a dredger. In other environments, we can confidently say you can use it; we design according to different conditions. We have a variety of sand pumps, with smaller ones capable of removing 5-60 cubic meters per hour, and larger models that can extract over 800 cubic meters. We tailor our designs to the actual working environment, considering sand pumping depth and sediment disposal distance. Generally, we use either a cutter-suction dredger or a jet-suction dredger; choose one of the two. The cutter-suction dredger is more expensive but suitable for a wider range of environments. The jet-suction dredger is more affordable but is only suitable for environments where sand collapse is an issue. For specifics, feel free to consult our company experts directly!
