Proven reliability and energy savings under all modern wastewater conditions
The Grundfos SL range of wastewater pumps has been extended with frame size 56 pumps in the size of 18.5 to 41 kW, 50 Hz. To ensure the highest operational efficiency, the new range of SL pumps are fitted with IE4 motor components and the innovative Open S-tube® impeller.
The pumps are self-cleaning and are ideal for pumping wastewater with medium to extreme concentrations of fibres and suspended solids. They are available in a wide range of material variants, such as cast iron, stainless steel and high chromium white iron. Thanks to its compact design, the pump easily replaces most wastewater pumps with a minimum of system adjustments required.
Built to last in modern wastewater conditions
With the ability to self-clean and a capacity for large flows, the SE/SL frame size 56 wastewater pumps operate reliably and efficiently in even the toughest wastewater conditions. Watch this video to learn more about how we designed the new range of wastewater pumps to meet modern wastewater challenges.
Reduce energy consumption in wastewater pumping systems
Water utilities are responsible for 4% of the world’s total energy consumption*. Want to be part of the journey towards more efficient wastewater transport? Download this white paper to learn about eight ways you can optimise efficiency in your wastewater pumping station.
Regain maximum efficiency, with minimal effort
Wear and tear can cause wastewater pumps to lose efficiency by increasing the gap between the impeller and suction cover. Grundfos SmartTrim allows you to adjust the impeller gap to regain maximum efficiency. Watch this video to find out how it works.
