6105 Wide Flow

Roger,

In searching the forum, it looks like the 6205.130 came with the protective grating. Is this still the case? Just want to make sure before I order.

Thanks
 
Hi Roger,

Got the wide flow kits and they work great. I have always used the 12v jumpers and I always had one pump that was louder than the other. Especially prominent when it is ramping up and down. Was never that big of a deal, though.

I put the 18v jumpers in to compensate for the wider flow and the noise is now appreciably louder. Both pumps are actually noisy now. I ended up putting one of the 12v back in because of the noise. I can't imagine what the 24v jumpers would sound like (never got them).

My question is, is there anything I can do or replace that will quiet them down? I've had them for several years and overall very happy with them.

Thanks,

Jason
 
Are the pumps the older type from pre Nov 2011 with the removable shafts for the drive units or the new type with the fixed shafts?
 
Well, when I clean them, I can completely remove the shafts, so I am going to assume they were pre Nov 2011.

Thanks
 
OK, on the older ones, the shaft can oscillate as it is secured on the front and rear, the new ones are rigidly secured only at the rear. It is critical that the front covers fit securely, all gaps should be even and their should be no bow out at any of the clips where the front covers attach. The new design is at least 10db quieter. I would also check the drive units for wear, after 4-5 years they can have enough wear the replacing them will both reduce noise and improve performance.
 
Thanks Roger,

Maybe I am a little confused. I just went on the Tunze website and see the drive units (there are two of them), I thought these were the shafts. I can remove these for cleaning, I guess I never really looked if there was a fixed shaft that these went on..?

At any rate, which drive unit would I need? 6105.700 or 6105.701? I guess to be sure I will need to take them apart and see which picture on the web site matches the part I have.

Upon further inspection, it looks like 6105.700 has the shaft and .701 does not.

I am pretty sure I will need .700.

6105.700 is the older one, the shaft reaches to the front housing and has 2 blue bushings on either end. The 6105.701 is the new one, the shaft is part of the motor and only reaches to the top of the well the impeller rests in.
 
Hi Roger,

Got the new drive units and I have installed one on the louder pump I had. However, now it is literally 10 times louder. Before it was a hum that could be heard while next to the tank, now it is super loud and I can hear it anywhere in the house. Do they have a break in period? I tried both new drive units and they both sound the same.

I have left one in there for about a day and half and there has been no improvement. If the pumps were this loud when I bought them, I definitely would have returned them. At this point, I think I will have to take out the old drive unit and take the wide flow kit off. The noise is pretty much unbearable, I am actually worried about the toll this takes on the fish, as it can't be pleasant to hear this amplified through the water 24/7.

Any suggestions would be appreciated. I have already taken the pump apart 2 or three times to make sure that the shaft is seated properly. Also, swapped out the new drive units and there is no difference, so I am worried that it is something with the motor, which would be the only thing I haven't changed out at this point.

I realize the pumps are several years old and have gotten good use out of them, just thought I could change it up with the wide flow and 18v jumper.

Sorry for the long post.

Thanks,
Jason

I am happy to take a look at them if you send them in, or even send one in, that may give us the answer. Unfortunately the older generation of pumps were louder, average 62 db which is about the noise level outdoors in a quiet neighborhood, compared to 52 db now which is about the noise level in a quiet house. The new drive units do have some break in and db is not the full picture of noise, pitch is far more annoying than the pressure of the noise, a higher db, lower pitch is perceived as less annoying. In general we have had a rule of thumb with new drive units/ new pumps that 50% of the noise will be reduced in 2 weeks of run time, a further 50% reduction will occur after 2 months so after 2 months you will have 75% of the starting noise. This is due both to air trapped in small spaces and seating and wear of the parts.
 
Hi Roger,

At this point, I will let it run for another day or two and see if there is any improvement. Although, I will say even a 75% reduction I think will still be loud.

I also may put it in my salt mixing brute can and letting it run in there for a few weeks.

If they are that loud, something has to be wrong and while they may be older and out of warranty, if you give me a chance I will find a way to make it right, it may not be free, but definitely less than buying new and I would like to keep you as a Tunze user.
 
Thanks Roger, your service has always been A1. That's why I have a tunze skimmer, osmolator and magnet cleaner too!

I will see how it goes the next week or so. I haven't tried the other 6105 yet, but will put one of the new shafts in that one to see how that sounds.

Just for kicks I will also put the old shaft back in the one I originally swapped out. I know sometimes changing things around can cause issues and I will see if the pump quiets back down.

If the noise continues, I will send it in.

Roger,

I figured out what is causing the noise. It is actually the clamp that holds the pump. If I take the pump out of the bracket and just hold it, it is silent. As soon as I put it in the bracket (free floating, not connected to the glass), it hums/rattles really loud. I think there is a lot more torque with the wide flow kit and the 18v jumper, every time it ramps up, I can really feel it when I am holding it.

Any suggestions on what to do? I tried the pumps on both clamps and it does the same thing.

Thanks,
Jason
 
Do you have the older 6065.510 clamp or the newer style with the silicon isolators (6065.650)? Are you sure the magnet is not damaged in some way or missing the rubber feet so it makes direct contact with the glass?
 
Roger,

I will check the clamp. It does have the 4 bumpers, if that is what you are talking about. However, most of the noise is generated from the contact between the clamp and pump, not the clamp and glass. If I hold the clamp away from the glass, it vibrates and makes a lot of noise.

When I attach it to the glass and the other magnet, the noise does get amplified. I did notice the four bumpers on the clamp side were pushed in and I guess there may be a chance of the clamp contacting the glass directly too.

Thanks,

Jason
 
So the clamps you have have the clamp, 4 blue silicon tubes and then the piece to attach them to the magnet? This style clamp should stop the vibration transfer to the magnet and on to the glass.
 
Hi Roger,

Looking at the web site, I definitely do not have the new style clamps. I guess I will order a couple of those and cross my fingers!

Thanks,

Jason
