1073.04 Impeller Options

[Typlus5]

I've been curious about my return pump getting louder over the past few weeks and found the culprit. What are the normal warranty options?

If it is less than 2 years old, email me a copy of the receipt-

It's over 2 years.

You can just order this part on Tunze.com, part 1073.047. They are pricey as they use rare earth magnets, about $60.

Ugh... same here for me.

The last week or two there's been an unfamiliar hum from my system. Took the pump apart... and it looks just like yours.

I wonder if this is typical wear and tear. Mine is approaching 5 years in service.

What did you wind up doing?

I just ordered an exact replacement Tunze pump. I'm not thrilled with the longevity, or the price of the replacement pump, but it is *so* quiet.

I wonder if a replacement impeller would be a wise investment... to have a backup pump on hand. I wonder if the motor is still fine.

I have been keeping aquariums for about 30 years now, 5 years from an impeller is not that bad, even the most simple and bulletproof pumps will need an impeller between 5-10 years and typically good AC pump motors last about 10 years. The impeller is part 1073.047, they cost $57.80 and can be ordered on Tunze.com.

Thanks. I'll be ordering one to have a spare pump.

You think the failure is due to friction? Expansion and contraction? Poltergeists?

Usually when I see them do this they look like in the photo above, something scored the plastic (gravel or other foreign object) that coats the magnet. This impeller uses a neodymium magnet and they corrode so once the plastic is cut, they swell up and are ruined.
