The DNB series is used for pumping and draining clear liquids and wastewater. The special geometry of the S-Flow two-channel impellers enables the pumping of liquids containing suspended solids with short fibers, making them particularly suitable for wastewater treatment plants. The 4-pole versions are suitable for continuous-duty operation (S1) and are distinguished by exceptionally quiet operation. All major components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, located in an oil chamber, ensures a long product service life. Cooling is provided by the liquid in which the pump is immersed.
Motors:
- squirrel-cage motor available in 2- and 4-pole versions
- thermal protection built into the winding
- Insulation class F (155°C)
- IP68 protection rating
