Restore Mag-Drive Performance
The Atlantic Water Gardens impeller assembly for the TidalWave MD1000 is the complete replacement impeller unit for this 1,080 GPH (4,088 LPH) mag-drive pump. With a 90W motor and 20-foot cord, the MD1000 is a popular choice for decorative spillways, water walls, and medium-to-large fountain basins. Replacing the impeller assembly when flow drops restores full output and quieter operation.
Complete Assembly for Full Restoration
This replacement includes the impeller blade, ceramic shaft, and matched magnet core as a single pre-balanced unit. The MD1000 runs at higher wattage than smaller MD models, which can accelerate ceramic shaft wear in hard-water conditions. Replace at the first sign of noise — a light grinding at startup is the key warning indicator that the ceramic shaft is wearing against the housing's bearing pin.

How to Replace
Disconnect power and remove the MD1000 from the water feature. Open the front cover by rotating counter-clockwise. Remove the old impeller assembly and inspect the bearing cup for scoring. If the cup is undamaged, install the new assembly and reassemble. If the cup shows scoring, the pump housing may need replacement. Return to service after confirming smooth, noise-free operation.
Ideal for medium to large decorative water features, water walls, and spillway pond applications.
