Wilo-Rexa BLOC

Economical sewage transport in dry well installation

Your advantages
Wilo-RexaBloc RE

Economical sewage transport in dry well installation

Whether in intermediate pumping stations, collector pumping stations or wastewater treatment plants – sewage pumps of the Wilo-Rexa BLOC series with low-clogging impeller or single-channel impellers enable reliable and flood-proof sewage transport even in continuous operation. The standard-equipped IE3 standard motors and high overall efficiency keep energy costs low. Maintenance and servicing work is simplified and operating costs are minimised by the back pull-out design.

(*based on IEC 60034-30-1)


Your advantages

  • High operational reliability owing to closed bearing brackets with oil-filled sealing chamber, additional leakage chamber and two mechanical seals
  • Low energy costs due to high overall efficiency
  • Various Ceram coatings provide a long service life when pumping abrasive and corrosive fluids
  • A service-friendly and time-saving construction with back pull-out design keeps operating costs low
  • A horizontal or vertical installation offers high flexibility for local space availability
