For continuous or alternating operation Grundfos has pumps to move unscreened wastewater through sewage and stormwater systems. Low life cycle costs are assured by sturdy, high-efficiency hydraulics and motors. Sensor monitoring is available to further optimise your pumping system. Efficient single-channel or SuperVortex impellers allow for free passage of solids up to 100 mm. Highly robust grinder pumps further reduce the risk of clogging, ensuring maximum uptime and low operating costs.
