Offset rollers and planetary gearing ensure dosing accuracy (±0.5%), low pulsation, and long tubing life Easy on tubing— reduces drag on tubing for longer tubing life and reduced risk of premature failure.
Benefits of a Pump Head with Planetary Drive System
With the planetary drive system, each roller is directly driven by the sun wheel. This mechanism prevents axial push-pull friction on the tubing—resulting in longer tubing life, lower pulsation, and high repeatability.
This pump head produces gentle, low pulse, and highly accurate dosing and flow to ensure optimal integrity and uniformity. Designed with offset rollers, the pump head provides linear flow throughout the flow range. While one roller is drawing fluid through one leg of the double-Y tube set, the other roller is pushing fluid through the other leg. Also, dual channels allow for a lower rpm in order to achieve “single-channel” flow rates. A lower rpm means reduced shear forces to maintain fluid and molecular integrity.
