The Ratio:Feeder® is a positive displacement, volume proportioning pump. Its design permits wide water flow ranges with minimal pressure loss. And lasting accuracy at all flow rates. Day to day maintenance is minimized by our design. There are NO SLIDING SEALS in the pumping mechanism. There is no metal in contact with the chemical (stainless check balls are used with fertilizers and some acids.). And there is an air gap between the chemical and the rest of the pump mechanism.
Several different series designs so you can choose the features you want or need:
- The Series J-Plus: our intermediate line
- Andy and Andy Jr. Series Injector Injectors
