which vertex doser is better da dc motor or da stepper motor?
Question by: jose hernandez on Feb 25, 2014 8:59:00 AM
Hi Jose,
Stepper motors are more precise motors. These are the same types of motors used in things like 3D printers, CNC mills, etc and are unique because they can identify where in a rotation they are and have the ability to turn a certain amount of a rotations (ie a certain number of "steps"). For example the stepper motor can make a precise 180 degree turn whereas a normal motor is on and off and will stop where ever it does. This isn't to say a normal dosing pump is going to coast a few extra turns or be inaccurate (in most folks cases its not a big deal if they add 25.5 or 25.8ml of calcium solution for example), but at the end of the day, the stepper motor is the most precise option.

What size tubbing is required for this unit?

Thank you

Question by: Juan on Jun 28, 2014 2:12:00 PM
Hi Juan,
The doser uses compressing fittings which are pretty forgiving, but we mostly use 1/4" polyethylene tubing here. You can find the same stuff we use right here:

  • Vertex Libra Doser - Main Unit (Stepper Motor) By Gene on 7/15/2015

    I paid ton of money for a product that never dosed evenly. I downloaded the upgrade. Calibrated and calibrate and calibrated. I called BRS they said to re-download the upgrade. Every time I look at the Vertex dosing vessels they are at different levels. It would be a great product if it worked.
  • Super easy use By Penny on 8/5/2014

    It´s very easy to use and the accuracy is very high. I use it for balling and I'm very happy with the pump.
  • vertex libra By Rick on 6/9/2014

    Not quiet at all, and touch screen works half the time, otherwise good. spot checks of dose amounts appear accurate.
  • Good but.... By Q on 12/10/2013

    First, this doser is pretty. Something u don't want to hide under a cabinet. Works well too. I gave it 4 stars because mine arrived broken but pumps work. Programming it is easy. It does take a little getting used but for the most part it is not overly complex. There is a start time and end time. During this period it will dose the entire amount u set up. For the volume it asks how much which can be as little as 0.5 ml and then multiplied by number of doses to give u final volume. It then takes that volume and divides it into the hours u set up earlier and that's it. I would recommend using military time as it makes start and end simple. The stepper middle is fairly quite. U hear it turn on but it is not bothersome
  • Great dosing pump By Jorge on 3/26/2013

    It's very easy to operate and program. I had it set up with the dosing containers in less the 30 minutes. Both are great products and I would recommend this to anyone that wants a dosing pump.
