This is a genuine OEM replacement impeller specifically designed for the Iwaki MD-55R water pump. As the central moving component of your pump, the impeller is responsible for generating the powerful and consistent water flow essential for your aquarium's circulation and life support systems. Over time, impellers can wear down or become damaged, and this direct replacement part ensures you can restore your trusted Iwaki pump to its original performance without needing to replace the entire unit.

Engineered to the exact specifications of the original, this replacement impeller guarantees a perfect fit and optimal function within the MD-55R pump housing. It features a robust magnetic drive assembly, characteristic of Iwaki's renowned durability and reliability. By using an authentic Iwaki part, you maintain the pump's efficiency, quiet operation, and longevity, ensuring your system's return lines, chillers, or other equipment receive the correct flow rate as intended by the manufacturer.

This replacement impeller is the ideal solution for saltwater aquarists who already own an Iwaki MD-55R pump and are performing routine maintenance or troubleshooting a decrease in performance. If your pump has become noisy, has reduced output, or has stopped moving water altogether, a worn or broken impeller is often the cause. Swapping in this new part is a cost-effective and straightforward repair that extends the life of your high-quality pump, protecting your investment and the stability of your reef aquarium.
