Abstract
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).
