N2 - Cutter Suction Dredger (CSD) is a type of dredger which works hydraulically by using a slurry pump to move material to the disposal site. In the selection of slurry pumps, the calculations used are not the same as those of pumps in general. This is due to differences in the characteristics of the fluid, especially its density. In addition, because pump performance data generally uses water as a fluid, a performance correction calculation is needed to obtain the appropriate value. In this project the aims are to identify the characteristics of the fluid, select the slurry pump and design the impeller based on API 610 standard. The stages in this project are divided into calculation; selection; and design. The results showed the slurry fluid has a characteristics, specifically: Density of 1269 kg.m−3; Specific Gravity of 1,269; and Dynamic Viscosity of 0,0,016,252 kg.m−1.s−1. The Head effective installation analytically is 58.215 m and numerically, using Pipe Flow Expert software, is 58,216 m thus resulted error rate of 0,0023% within the allowable limit < 2%. Therefore, in this CSD project, the slurry pump used is Shijiazhuang Nainater Slurry Pump Co., Ltd 450 WN with moderate-speed impeller type; Blade Inlet Diameter 0,631 m; Blade Outlet Diameter 1,263 m; Blade Inlet Angle 15, 98°; Blade Outlet Angle 25°; and Number of Blades 5.
