Clicking sound 6055 with 7095 controller

[Annie&Mylo]

I've just bought two new disc for drive (6025.740) and 2 new drive units (6025.700).

I have two 6055 pumps which are hooked up to a 7095 Tunze wave controller.

The problem was/is I get a loud clicking noise in every wave setting Except for Interval 2 where the pumps are on continiously. The click happens as the pump is about to start. Scares the fish Really a shame as the interval 1 setting creates the most natural wave current in my opinion
Whats wrong? Can't be the drive units anymore surely as they are new?

Any help would be greatly apprichiated!

Many thanks.

I don't really know either but I have a 6045 that makes the same loud clicking when it has started.

You need drive unit 6055.70, it is a new part that isn't in the older manuals. The prop is fixed with more tension to the shaft.

Do I need any new discs for the drives or can I just use the 6025.740? Thanks for your reply. Can I get 6055.70 in the Tunze online shop?

Interesting. Mine do the same. I just thought this was normal. I would like to order some as well.

It is normal on the 6025 and 6045 for a few seconds at most on start up but the 6055 should not, earlier pumps did and then we developed the new drive unit to solve that. As long as you have the black 6025.74 it should be OK. The disks should be stacked 2 high in a 6055, you can leave the old white one and put a black one on top. You should be able to get the 6055.70 under warranty.

I just ordered 2 new 6055's (should be here in acouple of days)

How do I tell if they are the "fixed" ones?

hi roger,

Just checking a couple of things:

1. is the new driver part 6055.70 or 6055.700 ... I only see 6055.700 at tunze.com (http://tunze.com/149.html?&L=1&C=US&user_tunzeprod_pi1[predid]=-infoxspare_9999.999) but am not sure if the website is up to date or not.

2. aside from the clicking noise issue, is there any down side to NOT upgrading to the new driver (e.g., will the pumps get damaged)?

thanks

The clicking was solved last November and the 6055's turn quickly and are made in much lower volumes because of the complexity so anything ordered now will be new. The only draw back to using the old drive unit is the click. Our part numbers are always seven digit but the 6th digit indicates it is a sub assembly and the 7th indicates it is a sub assembly of a sub assembly so we typically drop the 7th digit it casual use, it is very rarely used. For example 3000.60 is a drive unit, 3000.61 is the upper bearing, 3000.612 is the oring of the upper bearing.
