The Atlantic Water Gardens Aquarius Universal 800 and SP500/800 replacement impeller is the factory-matched service part for the Oase Aquarius Universal 800 statuary and fountain pump. When the pump's flow rate drops noticeably — or the pump runs louder than normal without a blockage — impeller wear or mineral accumulation is typically the cause. Installing a fresh OEM impeller restores the pump to its rated flow output without the cost of full pump replacement.
Compatible Models
This impeller is cross-compatible with both the Aquarius Universal 800 and the SP500/800 pump bodies — two closely related Oase pump models that share the same impeller chamber geometry. The SP500/800 designation indicates the part also fits the Oase Statuary Pump SP500 and SP800 models in the same family.
Installation
Disassemble the pump per the Oase service manual. Remove the front cover and impeller chamber. Pull the spent impeller straight off the motor shaft and press the replacement impeller onto the shaft until it seats fully. Reassemble in reverse order. No tools are required for most Aquarius impeller replacements.
