Construction features
Part No.
Vertical centrifugal immersion pump for stationary application. The robust pump shaft is mounted in an upper pedestal and supported by twoantifriction bearings. This construction, with the bearings spaced along thepedestal, ensures that any radial or axial forces are absorbed, even underheavy load. The result is a very smooth running pump. The solid version withsupport bars prevents the rotating elements from making contact with the pump
housing and guarantees a very long service life, even in continuous useapplications. As neither bearing nor seals are in contact with the liquid, thepump is very wear-resistant and suitable for dry running operation.

by the suction tube option. A suction strainer welded onto the cover of the pump housing or onto the extension tube protects the pump against the ingress of coarse impurities.A range of carefully chosen impeller diameters, together with a range of three-phasemotors in differing kW-ratings, ensures the optimum selection of pumps to meet thespecific operating requirements.
