Fixed Ratio Hydra-Cat proportioners accurately pump plural-component materials by powering two or three positive displacement pumps from a common air motor. This assures that the stroke rate and stroke length of all pump lowers are identical, providing constant proportioning. Models with two identically-sized lowers provide balanced pumping forces which prevents premature packing wear.
- Severe Duty lowers for wear-resistance and durability
- Two-pump lower offers a consistent 1:1 mix ratio
- PTFE packings are standard on Hydra-Cat lowers
