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.

How to Use

Remove and unplug the AquaSurge Pro. Open the casing and remove the worn impeller assembly, noting the position and orientation of the flow-adjustment components. Install the replacement impeller assembly from the kit in the same orientation. Replace the O-ring. Reassemble the casing and test the pump at minimum, mid, and maximum flow settings in a water container, confirming smooth adjustment response and appropriate output at each setting before returning to the pond.

Ideal for maintaining AquaSurge Pro 2000-4000 adjustable flow pumps in combination pond systems where variable pump speed is used to modify waterfall height or stream velocity seasonally.
