The gas jet pump (12) has a suction housing (19) with connector fittings (20, 21) for a propellant gas and the pumped medium, and a downstream mixer tube (23). The gas jet pump is located within the liquid ring pump (11) suction inlet (16). The gas jet pump has a connection flange located above the mixer pipe, which connects with the liquid ring pump suction inlet connector. The mixer pipe extends into the suction chamber defined by liquid ring pump housing.</p> |
