Torque Flow Pumps

Torque flow pumps from EDUR have a compact design that is unsusceptible to cavitation. They ensure smooth transport of solids-containing fluids.

Fields of Application and Conveyed Fluids

EDUR-torque flow pumps are especially used within water and wastewater technology as well as in industrial cleaning technology. Here, torque flow pumps are used both for the supply of solids-containing fluids and for the supply of suspensions. Typical conveyed fluids are

  • Wastewaters
  • Cooling lubricants interfused with chips, grinding oils or suds
  • Lime milk
  • Fluid media transported within liquids.

Variants of the EDUR-Torque Flow Pump

EDUR Torque Flow Pump FUB-Series

EDUR-proven torque flow pumps are the FUB and CBF series. These torque flow pumps in compact close-coupled design are available in a variety of construction styles and materials, such as grey cast iron or stainless steel, and can be configured with various sealing systems and drive solutions. As required, we deliver customer-specific configurations. Of course, we also provide certificates of all authorized classification societies and necessary test reports.
