In practice soil properties may vary from free-flowing to hard-toexcavate material. When used for estimation actual outputs, the nature of the material to be dredged and project conditions should be considered. CUTTER SUCTION DREDGERS (CSDs) MAIN FEATURES THE GRAPHS ARE BASED ON • output expressed in cubic meters of in-situ solids per effective pump hour • elevation at the end of the pipeline of 4 metres. IHC BEAVER® lowest cost per m3 available from stock lifetime support maximum uptime. MAXIMUM VOLUMETRIC CONCENTRATION To help you select the right Beaver® for your project, please use these graphs as a guide. A first selection can be made based on the pumping capacity of the dredger. The output of the various Beaver® dredgers for different types of sand is shown in the graphs that follow. This can then be matched with the required output and distance to be pumped. The theoretical output graphs are based on the information as indicated below.
