How Variable Volume Pumps Work

Precision dispensing with variable volume pumps involves retracting a piston to aspirate fluids and extending it to dispense precise volumes. Calculating the required steps for aspiration or dispensing ensures accuracy, while mindful refill speeds and aspiration prevent pump damage. However, stepper motor-driven pumps face challenges like backlash, affecting accuracy and longevity. The Lee Company addresses this with mechanical and software backlash compensation methods, ensuring precise dispenses even with direction changes.

By understanding and compensating for backlash, users can maintain optimal pump performance, aided by The Lee Company's technical support for reliable fluid control solutions.
