Main benefits
  • Plug-and-pump installation without having to worry about overheating.
  • Clog-free pumping with free-flow vortex impeller and pump volute.
  • High wear resistance ensures years of cost-efficient pumping.
  • Slim design and low weight make the pump easy to move and handle.
  • Serviceability with modular design.
  • Non-overloading performance with two different impellers for each pump model. The small impeller allows the pump to run in low-level applications.

Benefits

Plug-and-pump installation

Plug in without having to worry about overheating. Built-in thermal protection protects the motor from overheating.

Clog-free pumping – avoid downtime with solid-proof hydraulics

Free-flow vortex impeller and pump volute make the sludge pump perfect for pumping solids.

Reliability and wear resistance

One investment for years of cost-efficient pumping. Impeller and pump housing are made from wear-resistant ductile iron. Vortex hydraulics minimize load on the shaft and bearings, which ensures reliable operation and maintained efficiency. Double mechanical shaft seal in oil bath with the primary seal in silicon carbide ensures safe operation and long life.

Convenient handling – designed to make your life easier

The motor parts in lightweight aluminum make the pump very easy to handle and install.

Serviceability

Save time and money with easy on-site service. Modular design lowers the overall service costs. Easy access to the electrical junction box.

Applications
  • AquaTronic - the intelligent option
    The world’s smartest dewatering pumps for applications in mines, construction sites and tunnels are equipped with the innovative AquaTronic. AquaTronic ensures correct motor rotation, gives motor protection, allows the pump to start via a level sensor, and gives you all the pump performance information in your PC, plus much more.

  • Dewatering in construction
    From roads and bridges to ditches and dams, construction sites are difficult places to work. Construction site managers need solid economic reasons for purchasing equipment. Our submersible dewatering pumps provide them.

  • Dewatering in tunneling
    A tunnel construction is a complex worksite were many different variables need to be taken into consideration, flooding is one of them. Our drainage and sludge submersible dewatering pumps are lightweight, portable and start when you plug them in.
