Vortex pump DV series

wastewaterwith asynchronous motorsubmersible

Product overview
The DV series are submersible wastewater pumps equipped with a non-clog vortex impeller, designed for pumping chemically non-aggressive wastewater containing suspended solids up to the model-specific diameter. They are suitable for drainage, lifting and wastewater handling in industrial and municipal applications.
