Improved Replacement Impeller for Top Fin PowerHead 30

thingiverse

The Top Fin PowerHead 30 is a cost-effective aquarium water pump, yet its cheap construction was evident even when new. After a month of use, it stopped working completely due to impeller failure. Upon inspection, it appeared the design was purposely subpar. To enhance performance, I redesigned the impeller, increasing its size to utilize more chamber space. Photos show the original on the left and my modified version on the right. Since installing the upgraded parts, water flow has significantly improved compared to when new. Time will tell if longevity increases; updates will be posted if necessary. If others use these PowerHeads, please share your experience. To Top Fin: If you adopt this design, perhaps some free fish are in order! Update 1: One unit cracked, so I thickened the walls for durability while maintaining fit. Print impeller with fins down; support is unnecessary. Rafting may be used due to limited plate space, but it might not be required.
