How Does the Number of Rollers Impact Pump Performance?

The number of rollers in the pump head determines the smoothness and pulsation of the flow. Pumps with more rollers (6–12) provide smoother flow, lower pulsation, and extended tubing life, making them ideal for precision dosing or handling sensitive fluids. Pumps with fewer rollers (2–4) produce higher pulsation and are better suited for bulk transfer where smoothness is less critical.
