After visiting web site...consistency seems to be the reason...along with the space saving factor and fewer service issues.
Still don't get it.
1. Their venturi / consistency is better than a Hydrominder or Dema Because?
2. Their consisitency is better than a dosing pump because?
3. Their specs say pressure rangge is 100-1000psi. Who the heck is running that much pressure to most of their stuff? Will it work at less than 100psi?
4. Seems it won't save any space over a dema. If you use a mixing tank for the solution and then pump it out you save no space at all. Plus you need at least the room of a 5 gallon bucket for your concentrate.
5. One plus might be that a single suction line can be equiped with 1-3 suction lines. Could be interesting if mixing more than one solution.
