The desilter unit BDS 125-20-K demonstrates the compact design of the desilters. It comprises a cyclone set with 4” cyclones (6 units) that are arranged in two rows. The unit can be used with centrifugal pump BP 125 as coupling unit. It is primarily used together with the BE 250-60 in tunneling work and on cutting sites. When also used with slurry tank ST 25-H, this results in an optimal system for perfect slurry preparation.
