My pump fluctuates between 32-34 W (rarely 31/35 W) and the power factor stays between 0.31 – 0.33. Air flow is 1300-1400 l/h. I’m not sure why the air flow has dropped a little, it was 1500 l/h when new. It doesn’t seem to affect the performance that much…

I would love to see the video, please send it to grumpy@grumpyreefer.net

If you would like to see a video of this issue, I would be happy to email it to you. Please send me an email address to forward it to.

Thank you,

I sent this email to Anton. I received a second pump today from Victor but I am getting same problem. I was wondering if you get the sam fluctuations when removing the air line from the silencer then measuring the air flow.Mine bounces around like craze . If I take an air flow reading from the top of the silencer by installing a hose on top it is not as bad but still some fluctuations.

Thanks

Kevin

Hi Anton

I’ve been monitoring the skimmer over the last couple of days. I must say I am not happy with it’s performance at all . When running the skimmer the water level inside the skimmer must run at about 3″ from the collar of the neck on the skimmer and at that it still performs poorly.
Here are some numbers which I tried to get to see if I could solve this mystery.
The wattage bounces around 36-42 Watts, which seems to be telling me its not running very stable.
Power Factor is measured at 26-32. 26 is extremely low!
Now on the other side of the story, when pinching the air line, the wattage is elevated upward, the actual water level in the skimmer drops lower, and the wattage does not fluctuate as much , things appear to be more stable.
Also when installing an air meter, the air bounces around excessively, from 2100l/h-900l/h with 1200 being the middle point, but when pinching the air line it seems to stabilize at around 1500l/h.
I would like to resolve this problem with you, but at this point I find this unacceptable.
I sent this e-mail to Victor as well. Victor originally has sent me a new volute but that did not seem to help.

Thanks

Kevin

Yes! but it should not make a difference if I pull the hose of the silencer since the silencer is bigger anyway so no restriction there.
