摘要： A seal device for a submersible machine, such as a pump or a mixer, the seal device being designed as an easily replaceable unit having two mechanical face seals parted by a room for a barrier liquid in which a pump impeller is located. The impeller circulates the barrier liquid passing the liquid along the seals and through cooling channels in the driving unit of the machine.

摘要： A pump impeller of a centrifugal- or a half axial type meant to pump liquids, mainly sewage water, the pump impeller including a hub provided with one or several vanes, the leading edges of which being strongly swept backwards. The size of the sweep angle (.alpha.) varies between 40 and 55 degrees at the connection with the hub, and 60 and 75 degrees at the periphery.

摘要： The invention concerns a method and a device for treating liquids, such as wastewater. According to the invention the liquid is transported by help of a pump (10) from the lower area of a tank (1) through a vertically directed pipe (3) up to a 180 degree bend (5) located above the water surface and where air is sucked in through openings in the bend. The air-liquid mixture is then guided through a second pipe (6) having its outlet (7) close to the tank bottom (2). In this area the flow is once more linked 180 degrees and is directed through a third pipe (8) ending close to the water surface. Thanks to the linking through the pipe (8), a decrease of the static head is obtained against which the pump (10) operates.

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 inlet part of the pump housing includes a collar which concentrically surrounds a corresponding opposite collar formed part of the pump impeller inlet, thus permitting any possible leakage flow to be 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 is arranged in front of the opening to a slot between the parts.

摘要： The hub is conically formed, and the vanes attached thereto are given a substantially radial direction; consequently, the turning axes of the vanes are situated in the center of the vanes, substantially bisecting the center of the vane chords. The turning axes are perpendicular to the impeller shaft.

摘要： An impeller for pumps, turbines, fans, etc., of the closed type, having a number of vanes arranged between cover discs. In order to reduce the secondary flows within the impeller, the secants between the suction side of the vane and the cover discs are displaced with respect to the intersections at the pressure side of the vane. This impeller is rotationally non-symmetrical.
