Horizontal, single stage centrifugal pump Fields of application:

Pumping of abrasive and/or abrasive and corrosive slurries


Design features:

  • Horizontal, single stage centrifugal pump
  • Closed impeller
  • Sectional view of the ROWA-E SeriesLong service life and steady efficiency due to adjustable gap
  • Back-pull-out design (enabling the impeller and seal to be easily inspected or replaced without dismantling the pipes)
  • Axial suction flange
  • Radial discharge flange (DN32 up to DN250 / ANSI 1 ¼” up to 10”), or tangential discharge flange (DN 300 / ANSI 12”)
  • Robust, oil lubricated anti-friction bearing
  • Single acting, product lubricated mechanical seal type DÜTEC®, alternative seals on request
  • Optional suction side wear plate made of SICcast®
