Colorado-based Hydro Innovations has introduced a new range of self-priming wastewater pumps made especially for pumping corrosive and abrasive water. Manufactured using CD4MCu, a duplex stainless steel thatÂ’s corrosion-resistant, the self-priming centrifugal wastewater pumps can also handle spherical solids up to 76mm in diameter with most models (100mm discharge and larger). The pumps are suitable for flows from 5 l/s up to 200 l/s and for pressures up to 40 meters.
The self-cleaning wear plate system in the series aims to allow the pump to handle stringy materials such as rags and wet-wipes. Operators can also use the pumpÂ’s large removable inspection cover-plate to quickly and safely access bigger items that make their way into the pump such as blankets or towels.
The centrifugal pumps can be mounted high and dry above wet wells (up to 7.6 meters), allowing easy access for maintenance or repair.
