Metering Pumps of the Dual-Precision Series
Highest precision for synchronized dosing, mixing and analysis.
The Dual Precision Series’ innovative design allows precise mixing, simultaneous dosing or out-of-phase delivery. Combining pumps on a single motor saves space and reduces motor control requirements without sacrificing precision. Furthermore, relative dispense volumes never change because the pumps spin on the same shaft.
Using different size pump heads and using different calibrations allow mixing ratios as high as 160:1. Rinse port options are available when pumping fluids that form precipitates.
The speed and direction are detected by an optical sensor for feedback independent of the stepper motor.
Depending on size each pump head is capable of a displacement of 25 to 4000 µL / stroke.
