Verderhus® screw centrifugal pumps combine the best features of centrifugal and positive displacement pumps to define a new standard for low head, high flow pumping. Verderhus® pumps transfer your product gently and efficiently. The open impeller allows large solids to be easily pumped that reduces the risk of cavitation, which can cause serious damage to a pump and to the production process. A Verderhus pump will lower both energy use and ownership costs.

Suitable for pumping thick sludge in wastewater treatment, Macerated food waste, Sewage waste, Circulation of lime chemical, Paper pulp, Mining.

  • Clog free operation, reliability for your process
  • Highly efficient, low energy consumption
  • Solids pumping up to 13% of the flow volume
  • Low-shear, gentle pumping action, results in less damage to the product
  • Minimal wear, even with abrasive fluids, longest life time

Wilo Rexabloc

Wilo-RexaBloc / RexaNorm RE

Wilo-RexaBloc / RexaNorm RE ~ sewage pump in block design with standard motor for stationary dry well installation.

  • High operational reliability due to shut bearing bracket design with oil-filled sealing chamber and additional leakage chamber.
  • Optionally with two mechanical seals for increased operational reliability.
  • Equipped with IE3 motors as standard.
  • Optionally available with IE4 premium motors.
  • Simple maintenance due to “back pullout” design. This means the motor and the impeller can be removed without needing to remove the hydraulics from the piping.
  • Channel and vortex impeller options
