Small- and Mid-Scale Applications
For lower flow rates the MSD Feed Pump provides the efficiency and reliability to ensure the lowest total cost of water in your RO system.
The MSD Feed Pump boasts efficiencies that are competitive with positive displacement pumps, while maintaining the smooth efficiency curve characteristic of centrifugal devices. This means that RO designers and operators need not worry about significant changes in energy consumption in the face of changing feedwater conditions.
Large- and Mega-Scale Applications
At larger scales, the efficiency of the MSD Feed Pump exceeds 86%. High efficiency and Super Duplex construction makes the MSD the go-to option for large-scale desaliantion facilities.
The MSD feed pump was used to achieve the world's lowest recorded SWRO energy consumption, in a unit commissioned by Saudi Arabia's Saline Water Conversion Corporation in 2021.
