Complete Mag-Drive Replacement
The Atlantic Water Gardens impeller assembly for the TidalWave MD350 mag-drive pump includes the complete replacement impeller unit. The MD350 delivers 370 GPH (1,400 LPH) at 25W — an efficient workhorse for small water features. Replacing a worn impeller assembly is faster and far more cost-effective than replacing the whole pump.
Mag-Drive Reliability Starts with the Impeller
The MD350's magnetic drive eliminates shaft seals, making it one of the most reliable pump designs for constant operation. The only wear item is the impeller assembly — specifically the ceramic shaft and its bearing cup. Hard water can etch and abrade the ceramic over time, causing noise and reducing flow. This genuine replacement restores the smooth, quiet operation that mag-drive pumps are known for.

How to Replace
Remove the MD350 from the water feature and unplug it. Rotate the front cover counter-clockwise to access the impeller chamber. Remove the old assembly, drop in the new one, and reinstall the cover. Confirm the impeller spins freely. Clean the screen and inspect the bearing cup annually. Safe for koi, goldfish, and aquatic plants.
Ideal for small pond features, fountain basins, and basalt column installations across Canadian seasons.
