The DNB series is used for pumping and draining clarified liquids and sewage. The special geometry of the two-channel S-Flow impellers enables the pumping of liquids containing suspended solids with short fibers and is perfect for sewage treatment plants. The 4-pole versions are suitable for continuous S1 operation and are particularly quiet. All main components are made of GG20 cast iron. A double mechanical seal in a back to back configuration, placed in the oil chamber, guarantees long product durability. Cooling is provided by the liquid in which the pump is immersed.
Engines:
- squirrel cage motor in 2 and 4 pole versions
- thermal protection built into the winding
- Insulation class F (155°C)
