Ratio Adjustment

Understanding the terms used with the Hydra–Cat (H.P.) System, how it functions, and how to find and set the correct ratios for your application is the key to easier, more versatile operation of your proportional system.

Be sure to read and understand the following information before operating the equipment.

Terms

Ratio refers to the simultaneous output of a certain volume of fluid by the primary and secondary pumps.

The primary pump (A) is directly under the air motor (H); it usually pumps the base fluid. The secondary pump (B) is on the opposite end of the lever arm (E); it usually pumps the catalyst. The ratio of the secondary pump(s) can be changed by adjusting the ratio adjustment screw

(C). See Fig. 4.

There are three main steps when applying the use of ratios:

(1)determine the ratio that is required, (2) calculate the ratio setting, and (3) set the ratio on the Hydra-Cat H.P. system.
