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 thrust are compensated by antifriction bearings of sufficient size. A hydraulically favourable re-routing is done by means of guiding devices in the stage casings.
Applications:
Centrifugal pumps of the series UEA with NPSH inducer stage are applied for trouble-free pumping under unfavourable conditions at suction side. The capability of the pumps in this series to handle liquids at the boiling point, allows a wide-ranging application when handling condensates, liquefied gases, refrigerants, LPG, and boiler feed water.
