The DNB series is used for pumping and draining clean liquids and wastewater. The special geometry of the S-Flow two-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 stand out for their exceptionally quiet operation. All main components are made of GG20 cast iron. The double mechanical seal in a back-to-back configuration, housed in an oil chamber, ensures 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
