Steel Series electric submersible pumps

High-performance, compact stainless steel submersible pumps for optimal service in household installations and small civil plants. Two different types of hydraulics are available for the maximum flexibility:

  • DRENO (DR steel) with multi-channel open impeller for applications with clear or slightly soiled wastewaters
  • DRAGA (DG steel) impeller for applications with heavily soiled wastewaters and solid bodies, thanks to the free passage of up to 40 mm.

The cooling system allows these pumps to be used even when only partially submerged and in particular the DR steel version is easily converted into a dry floor pump, with suction levels as little as 5 mm above the ground.
Every model undergoes pressurised testing to guarantee perfect assembly and operation of the gaskets, cable gland and mechanical seals.

Thanks to their convenience and ease of handling, steel models can also be used in emergencies for pumping-out flooding premises or for temporary installations for pumping from wells and tanks.
What's more, the DR steel version also provides an excellent lifting station installed inside the nanoBOX tank for the collection and transfer of domestic wastewaters.
