Kamoer FX-STP Seizing?

[Ultra Aquatics]

Just received my Kamoer FX-STP and whenever the ml/min goes higher then approximately 100 the wheels seem to lock up and don’t spin anymore.

I know it has a 120/ml min max so not sure if this is considered normal? I tried playing with the adjustment screw but didn’t seem to help.

When I first got mine I ran into this issue. I think this occurs when it's not calibrated correctly.

Thanks, it’s been running a few days and seems better. It might have needed to “break in” a little bit.

Mine has been really noisy. Kamoer support and coralvue had me lube the tube with silicon lube and lube the rollers. I even spent 45 dollars for a replacement roller and it’s still super noisy. I have a feeling it’s the motor. Anyone have this issue?

I believe the pharmed tubing is too tight around the roller because it is slightly too short. I unhooked the bottom of the tubing from the holder and left the top one in place and now I have no problem with it seizing at any speed. I am running 100mls per min currently with no problem. I am going to try to order replacement tubing and cut a section just a hair longer than the stock section and use the barbs from the original tubing. Then I will replace it with both ends in the holder.
