Product Questions

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
Question by: Jon L. on Jun 6, 2017 10:55:00 PM
These pumps have very low power consumption on the order of about 1-2 watts. Because of their very low operating voltage, they can continue to turn slowly if there is any stray voltage on the circuit, so we only recommend operating these on mechanical relay outlets to avoid this issue.

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?
Question by: steven on Nov 21, 2016 9:40:00 AM
Hey there, thanks for reaching out to us! For 2part dosing, the 50mL/min pump may be much to fast for minor adjustments. It would be better if you use the 1.1mL dosing pump. However, the timer is a great option for controlling that pump. All you would need besides those products would be 1/4" polyethylene tubing for your dosing lines. :-)

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
Question by: Chris on Jul 8, 2016 2:18:00 PM
Hi Chris,
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.

What is the size tubing that comes with this pump?
Question by: Joel Brewer on May 5, 2016 10:05:00 AM
Great question! The top-off doser comes with 3/16" inside diameter tubing.

BRS Top Off Doser Specs

  • 20 ft max head
  • 50mL/min flow rate is ideal for most top off systems
  • Will not back siphon
  • Precision two roller design extends pump life
  • Dimensions: 4" x 3.25" x 4.5"
  • 12 month tube life (at 4 hours of use per day)
  • 12 month Bulk Reef Supply warranty on pump motor and head
  • Includes 17 ft of tubing, mounting bracket, and directions
  • 6' electrical cord
 

 

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.

  • Great pump By Paul on 6/16/2017

    The 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 12/16/2016

    Use 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 12/6/2016

    I'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 3/10/2016

    First 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 3/7/2016

    Tops 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.
    Fallback OFF
    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.
  • Pump Does Not Last By Robert on 2/23/2016

    First pump i purchased about two years ago, and it lasted 16 months, second one is now running for 5 months and i think it is going to die to, won't buy another. I use these for ATO, will look for a better solution maybe lifter pump!
  • Not good as ATO pump By thomas on 1/19/2016

    My situation is not the norm so this may contribute to my problems with this pump. I draw water from 11 feet below in order to top off evaporation in my main tank through my sump. This pump is not good at this. It is too slow, loud and only lasted about 5 months. It seems like it had to run at least half the day in order to keep up with the evaporation in my 93 gallon cube.... Just terrible.

    I bought a Diaphragm pump instead with a pirate flag on it :).. In my setup it is extremly fast.... It just ran for 10 minutes to fill up my sump after a 2 days of evap... the BRS pump woul dhave taken 12 hours.
  • Works like a charm By LBK Reefer on 11/30/2015

    I have a fairly large reef at +2,500 gallons and found this pump to work very well as a dosing pumping. It is working fine and does not have any issues self priming. I was expecting to spend some time trying to set the pump up and it was super easy and ready to go in a couple of minutes. I have ordered 2 more!
  • Does the job. By Sean on 10/22/2015

    I've been using this top off pump for 2 months now and its working good.
  • Ok Pump, Died after 15 months By Motti on 9/9/2015

    Good while it lasted, The motor died after about 15 months of use. was probably on for less then an hour everyday.
  • Pump appears well built with accurate flow rate By Smilemkr on 7/21/2015

    Pump was in use for less than 2 mths and it ceased. The BRS team was quite good at arranging an RMA for this pump.
