High pressure pumps UEA
Horizontal, self-priming centrifugal pumps of the segmental type with closed impellers and a suction stage. The suction stage is installed at discharge side. It is arranged in parallel to the last liquid handling stage and operates acc. to the sucking-through principle.
The design UEA has an axial inlet with NPSH inducer stage. The axial thrust is compensated by single-impeller relief. The remaining axial thrusts are compensated by antifriction bearings of sufficient size. A hydraulically favourable re-routing is done by means of guiding devices in the stage casings.
