Single Stage Inline Pumps

EDUR-single stage inline pumps are space-saving, robust and efficient. Due to their reliability, they have been successfully used in many industrial areas.

Fields of Application and Conveyed Fluids

Our single stage EDUR-pumps in inline design are especially used within cooling technology, energy technology, industrial cleaning technology, water and wastewater technology or other industrial applications. They are most suitable for the supply of clean or slightly contaminated liquids.

Variants of the Single Stage EDUR-Inline Pump

We offer high-quality single stage inline pumps with our LUB series. They are manufactured in grey cast iron and are available in many construction styles and drive variants with a single-active mechanical seal. As required, we deliver customer-specific configurations for our customers. Of course, we also provide certificates of all authorized classification societies and necessary test reports.


As all EDUR-pumps, single stage inline pumps stand out due to their efficient, economic, reliable, and long-lasting performance. Compared with a conventional closed-coupled pump, the inline pump is an especially space-saving alternative. Moreover, further product advantages are outlined below:

Technical superiority

  • Axial thrust-free, open or load-relieved, closed impellers
  • Compensation of the radial forces due to diffuser elements in the ring housing
  • Low NPSH (Net Positive Suction Head) values

Process safety

  • Possible protection against dry run
  • Possible vacuum operation
  • Excellent control behaviour

High energy efficiency

  • Low flow velocities
  • Low velocity head differences


  • Modular design for customized solutions
  • Compact close-coupled design / minimal space requirements
    • Pullback design
    • Operational spacer coupling

Field of application

  • Flow rate: max. 220 m³/h
  • Head: max. 66 m
  • Permissible operating pressure: up to 10 bar
  • Temperature: -40 °C to +140 °C
  • Viscosity: up to 200 mm²/s
