Plank v3.5 Mixing Pump Upgrade

4 reviews
$ 34.99 $ 24.99

We're excited to have found a way to use a high quality Sicce Syncra Nano as the mixing chamber pump! Even quieter than the micro DC water pump we previously used, we've found the Sicce to be much more reliable as well.  Included with this upgrade kit is a custom volute developed just for the Nano in this application.

The power cord is now routed up the inside of the mixing chamber and through the Plank mounting platform, for a cleaner and more convenient installation.

The upgrade kit requires the square-front mounting platform that began shipping in January 2021.  If you have the first generation round style platform and want to upgrade, please contact us.

We're discounting these for all current Plank owners so everyone can get updated to the new pump.  Please include your original Plank order number in the checkout notes so we can make sure you get the correct parts!

The upgrade kit includes:

  • Sicce Syncra Nano pump
  • Internal mixing chamber volute disk
  • Back half of the mounting platform (with power cord passthrough) Please select regular or XL as needed.

As we are an authorized Sicce dealer, the Syncra Nano carries a three year warranty through Sicce USA.

Video instructions on how to install the upgrade can be found on the Plank support page

Nice and quieeeeeeeeet

Wow, this pump is super quiet. i had the pump setup to only run when the feeder was on due to noise. this little pump is super duper quiet, now i let it run all the time. Once again, great service from AM and this shows they are never resting, always improving.

Love my plank

Great experience. Not only did you guys offer an upgrade but you informed me of it and offered it at a discount. Honestly I don’t know how you could have done a better job.

Best auto feeder on the market

I love what you did with v3.5. It resulted in a much cleaner installation on my system and the Sicce pump is just as silent as the old micro pump but seems to move a lot more water in the tube.

New Plank Design & Sicce Pump

I fried my original pump by plugging the wrong power cord into it. I contacted Avast Marine for help locating the replacement pump on their website. They got back to me the next day and advised me of the redesign coming out soon and they would notify me when they did. I was notified the other day, placed my order and new pump and revamped parts arrived in no time. I was going to wait until the morning to assemble it so that I had more brain power and wouldn’t get frustrated. Excitement got the better of me and watching the video, I had it assembled in a few minutes that evening. Extremely pleased with Avast’s customer service. I really like that they’ve chosen a Sicce pump. The redesign of the pump’s power cord is now completely hidden, coming up from inside the tube. I only watched the feeder in action once today and I feel like it performs better in the sense of the food coming out of the tube. The Avast Plank brings me the most joy of anything I’ve purchased for the aquarium.
