High-Flow Impeller for Large Pond Filtration Pumps
The Oase AquaMax Eco Classic 3600 / Premium 4000 impeller is the OEM rotor for the two highest-output pumps in the AquaMax Eco line. These pumps drive large-volume waterfall circuits and heavy-duty filter loops, so a worn impeller has an outsized impact on water clarity and circulation. Replacing it brings the pump back to its full rated flow.
Built for Heavy-Duty Circulation
Designed to move high volumes of water while maintaining low energy consumption, this impeller fits both the Classic 3600 and Premium 4000 motor assemblies. The magnetic-drive design eliminates leak-prone mechanical seals, and the precision-moulded blades maximise hydraulic efficiency at every RPM.

Installation
Disconnect the pump from power. Open the housing, remove the spent impeller from the shaft, and press the replacement on. Reassemble, submerge, and restore power. The swap takes roughly ten minutes with no tools.
Ideal for large koi ponds, multi-stream waterfall systems, and high-flow filtration loops that depend on sustained volume from the AquaMax 3600 or 4000.
