BRS Top Off Dosers are intermittent duty pumps and not meant for continuous operation. We recommend on/off cycles under a few hours to maximize life span. This is a higher RPM motor than the BRS 2 Part Doser and may make a small amount of noise in operation but is much quieter than most dosing pumps in this flow rate range. Mounting the pump to the inside of a wooden stand will amplify sound.
where is the zero star option By Underground Reefs on 1/28/2020Underground Reefs wouldn't recommend this product to a friendThis product gets 1 more star than it deserves only because the 0 star option is not available. I have had at least 10 of these units over the past five years. There is a cheap little motor on the inside of it that has a 100 percent fail rate within 1 year. I have found similar little motors to this but can't find the exact one that is inside of the pump. Based on what I have seen it cant be more than a $15 part.
After warrantying these out for years I am just done with them.
BRS does not offer this part or information on where to get it from.
Ecotech im sure will offer replacement parts for their new peristaltic pump as they do with their other equipment.
If you are able to bite the cost, go with them.
not reliable By david on 10/7/2019david wouldn't recommend this product to a friendI have owned two of these. The same gear wears out in about 6 months each time.
For the price, didn't last, noisy By Herbert on 8/3/2018Herbert wouldn't recommend this product to a friendVery disappointed with the longevity, didn't last long with only using less than 1 hr a day. Loud while running. For the price it should have lasted longer.
works. . . till it doesn't By Ryan on 2/22/2018Ryan would recommend this product to a friendmy setup pumps from the basement like many others so I can't use a normal diaphragm pump. I first tried the diaphragm pump with the flag on (hint hint) and it sounded like a jet engine in my stand so it went back. I've been using the BRS pump for a little over a year now and the gears are done on it. That said, i'm buying a new one because choices are limited. I'd pay extra for a pump with metal gears instead of plastic.
the tubing lasts forever
fairly quiet (slight clicking noise)
gears strip out with use
wish it pumped a little faster 100ml/min would be gear.
Overpriced By Luke on 11/1/2017Luke wouldn't recommend this product to a friendI bought this pump off the recommendation of brs for pumping water through a single di canister because of a degassing setup i have. it takes hours for it to push to do 25 gallons. For $80 I was expecting a pump that could actually perform. wouldn't buy again.
Temporarily great pump By Mark on 8/17/2017Mark would recommend this product to a friendThis pump will do a great job until an internal gear gives out and the whole enchilada goes south. Mark's re-engineer-it dept says: make that gear out of a BETTER MATERIAL and all will be well, Duh!
Lasted 6 years By Santa Monica Filtration on 7/24/2017Santa Monica Filtration would recommend this product to a friendOur gears just stripped out today, after topping off with lime water for 6 years. Never replaced the silicon tubing either. Yes it is a bit noisy, but we just cushioned it with foam and it's fine, and also the noise reminds you it's working.
Great pump By Paul on 6/16/2017Paul would recommend this product to a friendThe cost may be high for a pump that has no replaceable parts other than the tubes. However I have gone through 2 of these pumps and am on my 3rd. The second one started making gear noise so I knew I needed to replace it before it went. I use mine for top off dosing and have it attached to my Apex controller so I can program it so it doesn't wear out prematurely. I have it set to wait 10 seconds before turning on to eliminate water movement false starts. I also ensure it runs an extra 30 seconds after the float switch turns off to ensure there's a longer period before it needs to turn back on. They seem to last 2 years before they need to be replaced. Also they perform best when the tubing is replaced about every 6 months or so.
Don't expect to last forever By Dave G on 12/16/2016Dave G would recommend this product to a friendUse for Kalkwasser. I'm on my third one. On average last about 18months before the gears strips out dispensing about 2 gallons per day. Still when you factor in the higher cost of better options you can buy several of these before you would ever break even. Seem to go on sale fairly frequently ( expecially Black Friday ) so I plan ahead and buy a backup when on sale.
Working for my application By Chris on 12/6/2016Chris would recommend this product to a friendI'm using this as a basic topoff pump for a small reef tank...fed from a 5 gallon bucket that is in the tank stand. On/off times controlled by my Reefkeeper. Working fine for me for about 4 months now, although it is a bit noisy (I set it to dose late at night so...not really an issue).
Not sure how it would work for a more complicated installation with more head pressure required.
2nd Pump died just out of Warranty By MACEY on 3/10/2016MACEY wouldn't recommend this product to a friendFirst one died and it was replace quickly and easily by BRS, but now second one has died and the warranty is still tied to the initial purchase even though they sent me a new pump. Worked good while it lasted, pulling about 11 feed of head (well within the 20 foot rating). Looking for another alternative.
Great Top Off By Tiberius on 3/7/2016Tiberius would recommend this product to a friendTops off your system slowly so you don't get swings in conductivity. If you want this pump to last longer don't let it run more than 10 minutes at a time. You can do this with an oscillating function in apex. Ex.
OSC 000:00/010:00/005:00 Then ON
If Sw1 CLOSED Then OFF
If Sw2 OPEN Then OFF
Depending on the polarity of your float switches.
What is the wattage rating of these? Can I use on a TRIAC outlet? I find when on a relay outlet, on my EB8, there's an off transition transient that makes my LED's flash. I don't want to burn up my LED's
Have a great day!
Hey if I buy this dosing pumo and also 24-Hour Grounded Digital Timer - Hamilton (the timer), I am ready to go right? Do I have to buy other parts to make this work? Also the ditgital timer I am buying is it safe or not?
Can the doser pump be mounted sideways? The inlet and outlet tubing would be positioned to the right. Also, what is the electrical chord length? Thanks
The BRS Top Off Doser can be mounted in any orientation. Upside down, sideways, or vertical it does not affect the pump or the mounting bracket. Depending on the position it is mounted in will dictate where the inlet and outlet tubes will be placed since they cannot be adjusted on the pump.
The electrical cord is 6 feet long.
