摘要

The pump comprises a first tube section for connecting to a compressed air source and linked to a conduit arrangement, a second tube section comprising an outlet part and at least one nozzle in communication with the conduit arrangement and vessel. The first and second sections can move relative to each other. The first includes a control device for operating an air throttle connected to outlet part in order to alter the air flow direction through the nozzle and create an overpressure or vacuum in the vessel. The second section is linked to the nozzle.
