DAB Feka FXS: Energy Efficiency in Sewage Pumping

Anti-Clogging Screw Impeller for Large Purification Plants

The DAB Feka FXS series represents innovation in the field of wastewater lifting. Thanks to the special Semi-Axial Screw Impeller , this pump offers higher hydraulic efficiency than traditional Vortex pumps, ensuring significant energy savings while maintaining a free passage of 50 mm.

  • ✅ Screw Technology: The hydraulic profile guides the solids out of the pump, reducing turbulence and consumption.
  • ✅ Ideal for Long Lifts: Perfect when the sewer pipe needs to be pushed very far (high head).
  • ✅ Certified: Complies with the EN 12050-1 regulation for wastewater containing faecal matter.

Do you need to move a large sewer line and want to lower your bill?

In large condominium or industrial systems, pumps operate for many hours a day. A traditional Vortex pump is reliable but energy-hungry. The Feka FXS was created to solve this problem: its helical (screw) impeller is designed to cut through the water with minimal resistance, offering exceptional flow rate and head performance with more compact motors.

It is the ideal solution for municipal pumping stations, sewage treatment plants and large residential complexes where efficiency is a specification requirement.

🧠 Expert Guide: FXS, FXV or FXC?

DAB has created three versions of the same pump. Here's which one to choose:

  • FEKA FXS (This page): The "Green" choice. Uses a screw impeller.
    Best for: Sewage or raw sewage over long distances where you want to save energy.
  • FEKA FXV (Vortex): The "Tank" choice.
    Best for: Sewer with lots of rags, lint, and wipes . It uses more but never stops.
  • FEKA FXC (Canals): The "Drain Pump" choice.
    Best for: Rainwater or clean drains where huge volumes of water need to be moved quickly.

FXS Details: Flanged Outlet DN65 or DN80. Also available in ATEX (explosion-proof) version for installation in closed wells.

Smart Maintenance

The Feka FXS is built to last. The double silicon carbide mechanical seal system is protected in an oil chamber, away from wastewater. Furthermore, thanks to its modular construction, the hydraulics can be accessed for cleaning by unscrewing just a few bolts, without disassembling the engine.

Frequently Asked Questions about Feka FXS

What kind of mandate does it have?

The Feka FXS is an industrial pump: it has flanged delivery ports DN 65 or DN 80 (PN 10/16). It does not have a gas thread. To connect it, a counterflange or a coupling foot is required.

Does it clog up with toilet paper?

No, the screw impeller has a large free passage (50 mm) and is designed to convey solids towards the outlet. However, if the system is critical due to the presence of large quantities of nonwoven fabrics (wipes) , we recommend the FXV (Vortex) series.

Do you need the electrical panel?

Yes. Since they are high-power pumps (often three-phase TNA), they necessarily require a control panel (such as the DAB E.Box) with thermal protection and float switch management.
