Method and apparatus for pumping a medium. |
摘要 |
<p>The present invention discloses a method and a centrifugal pump for pumping fiber suspensions of the pulp and paper industry in which the fiber suspension is caused to flow into a centrifugal pump housing in which space a vortex flow is created to prevent the suspension from forming a strong fiber network and from causing blockage of the system. The centrifugal pump includes a housing provided with one inlet (22) and at least two non-symmetrical outlets (92, 94), at least one of the outlets being preferably provided with a means for regulating the flow through the outlet. The centrifugal pump further includes an impeller/rotor (78, 80) for moving the suspension through the several outlets (92, 94) towards further processing devices. <IMAGE></p> |
