The DNB series is used for pumping and draining clear liquids and wastewater. The special geometry of the S-Flow twin-channel impellers allows liquids containing suspended solids with short fibers to be pumped, making them ideal for wastewater treatment plants. The 4-pole versions are suitable for continuous S1 operation and are exceptionally quiet. All major components are made of GG20 cast iron. The back-to-back double mechanical seal, located in an oil chamber, ensures a long product life. The pump is cooled by the liquid in which it is submerged.
Motors:
- Squirrel-cage motor in 2- and 4-pole versions
- Thermal protection built into the winding
- Insulation class F (155°C)
- IP 68 protection rating
