Product Overview
The Watson-Marlow 120U/D1 is a precision-engineered peristaltic pump designed for accurate, low-shear fluid transfer in demanding industrial and laboratory environments. Manufactured by Watson-Marlow, a global leader in peristaltic pump technology, this model operates on the positive displacement principle using a rotating roller assembly that compresses a flexible tube to create a continuous, gentle pumping action. The 120U/D1 is a single-channel, fixed-speed drive unit engineered for reliable dosing, metering, and transfer of aggressive chemicals, viscous fluids, and shear-sensitive media. Its robust construction and simple tube-replacement design make it an ideal solution for continuous-duty applications where cross-contamination must be eliminated and maintenance downtime minimized.
