QV 80/361 - 1.5 kW / 50 Hz - raw sewage pump
Couldn't load pickup availability
State-of-the-art four-pole pumps for sewage and treatment plants, with Vortex impeller.
The submersible electric pump QV is characterized by a robust design and a Vortex impeller, which provides very high resistance to clogging thanks to large passages. At the same time, this impeller provides long-term resistance to wear and allows for versatile applications. These advantages compensate for the slightly lower efficiency than in pumps with channel impellers. QV pumps are especially recommended for water containing a large amount of solids and long fibers, dirty water and raw sewage , mixed and raw sludge, septic sludge, process water.
The connection flanges of QV pumps enable installation on coupling feet, which can be purchased as a separate product.
