FIELD: obtaining minerals from underwater, particularly hydro-mechanized devices for concretion production from seabed.
SUBSTANCE: device comprises movable seabed unit with pulp pump and outlet pipe, pressure pipeline with perforated part, basic ship and connection flanges. The perforated part is formed of parallel pipes connected with outlet pipe of the pulp pump and with pressure pipeline by distribution pipes. Number of pipes and pipe diameter are determined from 
where D1 is diameter of outlet pulp pump pipe, D2 and n - diameter and number of pipes composing perforated part of pressure pipeline.
EFFECT: increased productivity.
