Hi guys,

For the past few years my Blau reef motion pump has been running in my freshwater tank, pumping water from the sump back into the main tank.

Recently it has started to slow down, stutter occasionally, and this causes the water in my overflow to drop until it starts sucking on my bottom outlet, and making lots of noise.

What sort of life span do these pumps have? Is it time to replace it?

I do like the fact that I can alter it from 1-100% as this aids really fine adjustments and makes the tank run almost silent.

If It does need a replacement, what’s the pump to replace it with?

Thanks all.

J

I'm not sure if this may help, but maybe something such as algae is clogging up the input or output of the pump, slowing it down?

I do clean the outlet pipe regularly, and there is no inlet as it’s in the sump.
And I do take the pump apart every 2 months and clean the impeller and inside the housing.

So I don’t think it’s to do with the pipe work.

Thanks for the thought though.

Have you cleaned the propeller out.

Or do you have access to it I know some are built inside the case.

Had a similar thing with a pond pump, the ceramic shaft on the impeller had wear on it and that was causing a bit of play on the impeller itself, new impeller and shaft and the problem was sorted.

I have changed the impeller, so maybe I need to try and replace the rubber/plastic bushings at each end.

But I doubt I will be able to find them to buy, finding a new impeller was hard enough.

That’s why I was asking how long are pumps meant to last?

Cannot say, I've been running an Eheim 2236 for 10 years without hassle, JBL E900 again with out hassle for 6 years and the same pond pump for 5 years with that one impeller incident. With regular maintenance I think the life span is endless.
