- Syncra Silent 4.0 Pump (951 GPH) - Sicce
Why does BRS recommend this?
The Syncra Silent line of pumps come in many different sizes and will fit most tank needs. Sicce uses high-quality magnets in their pumps, which allows them to spin smoother with less noise than almost all other pumps in their price category. If your tank needs a high flow return pump or a smaller pump for a low flow reactor our first choice will always be Sicce.

Good product until you have an issue By Pixel Reef on 2/13/2019Pixel Reef wouldn't recommend this product to a friendThe pump worked great until the impeller broke. Sicce customer service is non-existent. BRS does not carry parts. Very disappointed after all the reviews and BRS endorsements. I have several Sicce pumps and will not buy any more as there is no support.
Great pump By Cody on 1/5/2019Cody would recommend this product to a friendI love the adjustability of it, works very well
Quiet but Too many issues! By DEE on 8/13/2018DEE wouldn't recommend this product to a friendBought two of these 4.0 pumps and maybe I just got 2 bad ones? Within the first month pump number one stopped working. Contacted customer service and was told if I dosed 2-part it was most likely frozen from calcium buildup on the shaft (doesn't everyone dose?) So I cleaned it and it worked again. Month 2 and the second pump stopped working, except this time the bearing broke. Bought replacement and I was back in business. Month 4 and pump one stops working again. Took it apart to clean it and found a broken shaft ($100 to replace) I currently have a warrantee claim in but will likely change over to Reef Octopus once this all gets straightened out. when they work, they work pretty good but to have to beak them down once a month seem like too much to me for a new pump.
Nice, Quiet Pump By GERALD on 2/20/2018GERALD would recommend this product to a friendThis is a very quiet pump. I use it externally and you can barely hear it running.
Powerful, with a little hum and vibration. By Gregory on 7/9/2017Gregory would recommend this product to a friendJust set this pump up to tumble biopellets in "BR-140 Biopellet Reactor - Reef Octopus" and it is doing a great job. I used the longer suction cup feet, but I could still hear the hum or vibration. So I set it on a section of Oxo mat that is sold at BRS to quite pumps and that reduced it further. It's only been running a day, but I expect/hope it gets quieter over the next couple of weeks. Overall I'm pleased with my purchase so far. Ehiem might be quieter, but not by much.
Astounding product and customer service By Daniel on 4/10/2017Daniel would recommend this product to a friendI had received the pump and due to my negligence, I forgot to make sure the impeller was secure. It had ended up causing the impeller to snap off as it was running, freely shaking within the chasis, scratching the pump's insides, heating the pump up and causing irreparable damage. I contacted BRS, expected to have to cash in for a replacement. To my surprise, BRS sent me one free, and I sent mine back some time later. This pump is incredibly powerful, silent, and robust. Just ensure that the impeller is nice and snug before operation! (as with any pump, for that matter)
Much quieter than Eheim 1260 By Scott on 2/27/2017Scott would recommend this product to a friendI have used Eheim 1260 pumps for years in my living room tank, but I could always hear the low vibration from my bedroom directly above. So when setting up a new Reefer 250, I decided to look for a quieter pump.
Syncras have a good reputation, but I read some rumblings that the larger models were not terribly quiet. I took a chance on the 4.0 model, and I am really glad I did. Once I mounted the (very long) suction cup legs to the pump, and let the pump break in for a few days, I would estimate that the Syncra makes only 25% the noise that the Eheim 1260 did. I would not call it silent, but it is extremely quiet, even when restricted. I cannot hear it from my bedroom anymore.
Time will tell regarding reliability, but for now, my old 1260 pumps will serve as backup.
Awesome Quiet By Bumgrundle on 4/12/2016Bumgrundle would recommend this product to a friendBest overall pump i've had to date. Just Superquiet and very nice adjustment dial instead of haveing to adjust a valve. Love it!
Great pump By Newbie on 4/2/2016Newbie would recommend this product to a friendNice and quiet, works great.
Great! By Kirby on 3/6/2016Kirby would recommend this product to a friendProduct arrived on time and well packaged. Does a great job for what I need.
Great Pump. By Robert on 8/24/2015Robert would recommend this product to a friendExcellent pump, super silent, and powerful. I have four Sicce pumps now and would recommend them to anyone looking for a reliable and silent pump.
Great pump By Spaz on 7/9/2015Spaz would recommend this product to a friendI use this as a return pump from the sump. It's quiet and has a super voluum of water. I turn it down most of the way using the built in control.
It doesn't look like the adjustable flow rate can be used if operated externally. Is this true?
That is correct, this pump is only adjustable when used internally, but we would recommend using a ball valve to adjust your flow if using this externally. Have a great day!
