The above output figures are based on the maximum available power on the dredging pump shaft and in the situation of 4.0m elevation height at end of discharge pipe. In actual practice, the nature of the material to be dredged and local working conditions must be considered. The figures are for reference only, and please consult HANSEL for professional suggestion.
