Greater free passage without compromising efficiency
Pumping wastewater is challenging. In addition to all states of water, pumps must be robust enough to ensure large solids, rags and fibers can pass freely without causing downtime and extra maintenance. The SL range of submersible wastewater pumps from Grundfos are designed to optimize your system performance with minimum servicing required.
The pumps feature either Grundfos S-tube® (SL1/SL2) or SuperVortex (SLV) impellers. The hydraulic design of the impeller ensures minimum clogging and maximum reliability without compromising free passage or total system efficiency. The free passage through the pump varies from 50-100 mm depending on size. When combined with intelligent controls and high-efficiency IEC and IE3 motor components, the SL range of pumps provides an ideal solution for challenging wastewater applications.
