    摘要: The invention concerns a device for sealing off the slot between a pump impeller and a pump housing in a centrifugal pump.
    The inlet part (2) of the pump housing (1) is designed with a collar (2) which concentrically surrounds a corresponding opposite collar formed part (5) of the pump impeller inlet, thus linking any possible leakage flow in parallel with the main flow into the impeller and minimizing the disturbance in the main flow.
    In order to minimize the leakage flow an O-ring (7) is arranged in front of the opening to the slot (8) between the parts (2) and (5).

    摘要: The invention concerns a device for a centrifugal pump impeller to be used when pumping polluted liquids.
    A cover disc (5) on the impeller (3) opposite the inlet (4) is provided with balancing openings (12) for balancing the axial force. The flow (F₂) through said openings is used for rinsing the leading edges (7) of the vanes (6) where pollutions tend to collect.

    摘要: The invention concerns a device for pump housings for centrifugal pumps for pumping of polluted liquids. In order to decrease the influence of radial force acting upon the impeller during operation, a partition wall (5) is arranged along a part of the turn in that part of the spiral formed pump housing that has the biggest diameter. In order to decrease the risk that pollutions will stick to the wall (5), it is split up into two parts (6) and (7) with an intermediate, longitudinal slot (10). The leading edges of said parts (6) and (7) are swept backwards into the slot (10).

    摘要: The invention concerns a device for an easily releasable mounting of a submersible mixer in a liquid tank.
    At the bottom of the tank there are provided supports (4), (5), while the under side of the mixer is provided with corresponding openings (6), (7) for receiving the supports. In order to prevent the reaction force from the propeller (2) from tilting the front end of the mixer upwards, at least one of the supports (5) is arranged at a level above the level of the propeller shaft.

    摘要: The invention concerns a device for obtaining an automatic circulation in waste water pumpstations.
    At the pressure side of the pump unit (6) there is a valve (6) which during a certain time opens a connection between the pump and the pump station thus creating a circulation. The valve (6) is opened and closed by help of communicating bellows (11) and (12) resp which are controlled by the pressure difference between two sections (9) and (10) resp in the valve (6) having different areas.
