There have been many changes to the 40 wetsides. Not so much on the dryside. Not to say that the MP40 has had its share of improvements to the dryside but I can't speak smartly on that, it seems that they occasionally make small improvements but don't advertise it.Hello
Quick? Did they redesign the pump, I thought I heard that. Only wonder because mine is 7-8 years old mp 40. I have taken it apart to clean maybe 10 times. I also run it on high to the point the motor is hot. Never a problem.
Asking since I wanted to pick up another
The guys here turned me onto this, I purchased a tube for 20$ and it will last me ten years. BTW I use some yesterday on a union seal https://www.dupont.com/content/dam/...iterature/Downloaded-TDS/0901b803809b781e.pdf
I think that sentence needs an "*" at the end. Like, the best pump with no motor in the tank perhaps. They are certainly not the most cost effective wave makers, nor the most reliable. But gotta love the small form factor and external motor...
How could that be? I have some of the older MP40s and have used vinegar on it hundreds of times and it never rusted, it is only the new quiet drive pumps rusting. Something changed in the manufacturing if it is vinegar. I use vinigar to clean all my pumps for over 30 years in the reef hobby and never has any of my other pumps rusted. Not only that there are those that also have the shaft rusting on the MP-40's since they switched from i think was ceramic.
The Grease looks like silicon grease..
There is the mp10, mp40 and mp60.. not ti forget that there was an mp20 back in the day that they stopped making. (It would be interesting to see if someone still has that model)
I remember a thread on reefcentral that a guy was boasting about his old mp40w (blue box) was still running strong. The president of Ecotech offered to trade a brand new mp40qd for the 1st gen vortech.I saw a post about an MP20 a week or two ago either here or on FB. I think they were looking for parts. Having had an early 40WES, I think it was the rebuild kit they used to offer with new ceramic bearings.
Some chemistry types pointed out that vinegar's chemical makeup allows it to penetrate plastics and break them down faster than other acids that don't penetrate plastics. There was a bit of a magnet crisis a few years ago and I believe many manufacturers swapped to a different type of magnet that is less corrosion resistant.
No, it was anecdotal, the consensus from the thread is to substitute vinegar with citric acid. But that was based purely on caution. Since we don't know the plastic used to encase the magnets, the experts can only speculate.I did see the thread but did not follow it all the way through.
Was it ever determined for sure vinegar is the issue?
There's not a doubt in my mind that they are constantly refining all their products.
Well, since your all here ill ask it here, sorry to the OP. I'll try to make this quick, on the MP10's can the impeller be taken apart from the magnet. I aske bc's the part the "holds down" the magnet to the housing with 3 tiny little clips broke off and i want to replace the hold down. Again sorry OP
