Graco Hydra-Cat Proportioning System

Accurately proportion plural-component materials

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 and Benefits

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
Teflon packings are standard on Hydra-Cat lowers
