Restore Adjustable Flow Across the AquaSurge Pro Range The Aquascape AquaSurge Pro 2000-4000 Adjustable Flow Impeller Kit is a factory replacement impeller assembly for AquaSurge Pro series pumps with variable output from 2,000 to 4,000 GPH (7,571 to 15,141 LPH). This kit is specifically designed for the adjustable flow variant of the AquaSurge Pro and retains the variable output capability across the full rated flow range when the original impeller has worn. Maintain the Full Variable Flow Range The AquaSurge Pro's adjustable flow feature is valuable in pond systems where seasonal or daily flow adjustments are needed to balance waterfall aesthetics with pond turnover requirements. When the impeller degrades, the pump may still operate but loses consistent response to the flow adjustment setting. This OEM kit restores precise variable flow control, not just basic pumping function.
