Abstract

The pump has a feed and simultaneous conveyor conduit (5), a hydrodynamic fluid media flow control unit (6) for control of the fluid medium in the required direction during the pump phases of "suction" and "delivery". A conveyor conduit (7) is provided to the fluid media forward flow point. A fluid medium feed container (8) ensures that the fluid level to be maintained in it causes the funnel connection of the fluid media flow control unit (6) remains hermetically closed. A combination device can be used for handling solid matter by means of fluid media using the hydrodynamic pump, avoiding the employment of cut-offs and other valves and taps affecting the fluid media flow.
