FIELD: material conveying equipment, particularly pneumatic transport devices.
SUBSTANCE: pump comprises chamber with inlet valve for material feeding and air-discharge valve, compressed air pipeline having valve for delivering compressed air to chamber and material transportation pipeline. Pump is provided with expansion pipe having rectilinear section, opened end and curved end. Curved end of above pipe is located near transportation pipeline inlet. Connected to curved end are nozzle and dispersing means forming turbulent jet of air-and-dust mixture at transportation pipeline inlet. Pump also has aeration means arranged at compressed air pipeline outlet to provide counterflow heat exchange between compressed air and material located between aeration means and opened end of expansion pipe.
EFFECT: reduced consumption of transportation agent for powder and fine-grained materials conveyance.
