ROWA-MC Series ROWA-MCC Series

Horizontal, single stage centrifugal pump


Fields of application:

Pumping of abrasive and/or abrasive and corrosive slurries.


Design features:

  • Partly Assembled Models of the ROWA-MC Series in the Assembly Hall Horizontal, single stage centrifugal pump
  • Closed impeller
  • Adjustable gap between impeller and wear plate
  • Back-pull-out design (enabling the impeller and seal to be easily inspected or replaced without dismantling the pipes)
  • Axial suction flange
  • Tangential discharge flange
  • Robustly, oil lubricated antifriction bearing
  • Single acting, product lubricated mechanical seal type DÜTEC®
  • Metal free hydraulic (wet area)

    Advantages:

    The pumps of the ROWA-MCC series are currently the most modern and durable technology for absorber recirculation pumps in flue gas desulphurization plants. The design enables to produce extreme large pumps with low costs. Under the aspect of lifetime, our SICcast® material exceeds conventionally materials by far. Regarding the metal free design of the wet hydraulic part, corrosion is principally not possible.
