Hydra-Cat Fixed Ratio Mechanical Proportioner
Multiple pump lower design accurately proportions two-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.
