Hydra-Cat Fixed Ratio Mechanical Proportioner

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. 

Models with three pump lowers and cylinders of various sizes can be selected to provide a wide variety of mix ratios.
Features
  • Severe Duty lowers for wear-resistance and durability.
  • Multiple pump lower configurations achieve a wide variety of mix ratios.
  • Two-pump lower offers a consistent 1:1 mix ratio.
  • Three-pump lower provides mix ratios above 1:1 for balanced pumping.
  • PTFE packings are standard on Hydra-Cat lowers.
