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.

- 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

Air consumption example | |
When the air pressure to the pump is 60 psi (410 kPa, 4.1 bar) and you are dispensing 1 gal. (3.8 liter) of mixed fluid per minute, air volume used, in cfm, will be about the same as the larger pressure ratio figure of your pump. See instruction manual for pressure ratios of pumps. Xper minute, air volume used, in cfm, will be about the same as the larger pressure ratio figure of your pump. See instruction manual for pressure ratios of pumps. |
