Depends before or after you apply the lubricantHow stiff is a Tunze shaft?
Tunze should be lubing their own shafts to proper stiffness spec. Not the customer.Depends before or after you apply the lubricant
Bigger question how long is the warranty on the Tunze shaft. We talking minutes or hours.How stiff is a Tunze shaft?
To a point. I have a Tunze 6025 or 6045 (not sure) running in my sump that hasn't been cleaned for about 13 years. Still going strong. On the other side, I've had 3 Tunze 6105's that have all died on me when the cable destroyed itself where it goes into the motor. At £230 each, that's a lot of wastage. Having said all that, I'd buy another one in a heartbeat if I could find one anywhere but they've been out of stock for about six months now.So we all agree? Tunze has quality parts?
Lots of good stuff in this post.Good food for thought here. I’ve seen MP’s recommended so many times on here, BRS, etc. that I’d always assumed they’re super reliable tried and true pumps. I even thought about buying 2 until I saw the price! Like all reviews I take everything with a grain of salt, and people who have problems will always be 10x amplified over those who set it and forgot it years ago with no problems. Maybe the real takeaway here is that most wave makers generally are just really hard working devices that are prone to failure and replacement. If so, the logical conclusion would be to spend as little as possible to get the flow you need knowing you’ll have to replace it.
That said, if I was going to spend $400 on a single pump I would expect it to be bulletproof. Even though you could consider the wet side a maintenance/replacement item, as others have stated it shouldn’t cost 1/4 the price of the entire unit and need replaced in less than 3-5 years. Not at these prices. Fundamentally the wet side is just some plastic and a ceramic shaft. The dry side is just a magnetic motor. It’s not rocket science and shouldn’t fetch NASA prices.
But I do think the toxic ad-hominem attacks need to stop. Just because someone judges an item as poor value doesn’t mean they can’t afford the hobby, or is poor, or doesn’t care about their reef and flow. End of the day a wave maker is very simple tech; a motor, a shaft, and a spinning blade to move water. It’s human nature to want to justify money spent, but it’s also not wrong for someone else to question the value proposition in the face of multiple failures and problems. Spending more money doesn’t necessarily mean higher quality or fewer problems but all too often that’s exactly what people try to argue even in the face of evidence to the contrary. To each their own, but for my part I’ll always be on the lookout for the best price:quality/longevity ratio and long term costs. Even if the price is sometimes high. However, I’d much rather run the risk of replacing a $100 pump every 1-2 years than spending $400 up front and still spending $100 every 1-2 years on replacement parts. That doesn’t make me poor or cheap, just financially literate. All things being equal.
What is "financially literate" tho?Lots of good stuff in this post.
Yeah, I questioned that too. Kind of a pot calling the kettle comment after an otherwise balanced post.What is "financially literate" tho?
Just saying if the experiences here are true and you’re going to shell out $400 per pump and still expect to spend $100 every 1-2 years on parts vs. sticking with $100 pumps, that’s not exactly a sound financial decision everything else being equal (which it may not be). It might be a fair decision for other reasons, but this whole thread is about whether the MP’s provide quality/reliability commensurate with their price (I.e. value) vs. alternatives.What is "financially literate" tho?
It seems to be about 50/50 between people that don't have problems with people that do.Just saying if the experiences here are true and you’re going to shell out $400 per pump and still expect to spend $100 every 1-2 years on parts vs. sticking with $100 pumps, that’s not exactly a sound financial decision everything else being equal (which it may not be).

Just bought 2 mp40 over tunze. The white shaft you lubricate? with what?Almost 4 years with a pair of MP40 with the same wetside. Cleaning, lubrication, proper spacer and alignment is what make them last. Still running strong. I also considered them expensive and avoided for a while, did a switch to test what was the hype about it and honestly very happy and will use it again.

I used citric acid. I have two sets of wet sides. I soak them for 24 hours then brush them off. Having two sets of wet makes it easy..one set is always ready to change out..Betting you didn't do routine maintenance of pulling, soaking in 5% Vinegar, then scrubbing with a toothbrush
Do that and you'll get 3 years

Is safe and I have been using it for a few years now. Only use a bit in the ceramic shaft and the bottom of the shaft. When you get a new wet side, they have a lubricant there. My only problem is that they use too much of the lubricant, usually I remove that one and use only a bit of this one. Im currently using 4 MP40 in my tank, two of those been there for almost 4 years, the other two for 3. all with the same wet sides from the beginning, none of them have corroded or stopped working. And running those at 50% all the time.
Please note I am being funny here making fun of ecotech saying they got wet... Perhaps the glass or the acrylic, depending on your tank ...allowed the magnet (dryside) to help water to somehow perform new version of osmosis and got the dry side ...WET...hahahah... and perhaps we should make a sticker to put on their sticker and send it back to them saying (you guys at ecotech are STUPID)Hahaha I started collecting those stickers! Total nonsense.
