The STH and STQ pumps from Fluid Metering (Syosset, NY) are suitable for precision mixing, diulating, and proportional metering for OEM medical, analytical, and industrial instrumentation. The pumps consist of two FMI valveless pump heads direct coupled to single variable speed drive, standardly a 23 frame stepper motor, although other drive types can be used. The displacement of each pump head is independently adjustable, and a variety of pump head sizes can be used in combinations to achieve dispensing ratios from 1:1 up to 500:1.
