Horizontal multistage centrifugal pumps with sectional casing and closed impellers. The manufacturing program covers six sizes, with 2 up to maximum 13 stages, according to the size, the speed and the shaft seal. Axial thrust balancing is carried out by balancing the impellers separately. The remaining axial thrusts are taken up by adequately sized antifriction bearings.
The impellers, diffusers, as well as the wear ring from size 65, are interchangeable between stages.
Arrangements combining impellers of different diameters permit, within the application field, optimum matching to the required performance characteristics with the performance curve.
On the suction side, the mounting feet are arranged on the casing of the first stage. By this means, it is possible to ensure easy adaptation to different installation conditions, even subsequent to initial installation, by pivoting the suction head casing.
The driver is arranged on the suction side but discharge side driver or driver on both sides are possible on request.
All sizes can be supplied with one or more dummy stages, on request.
