    How do peristaltic pumps work - sanitary

    Peristaltic pump working principle

    Peristaltic pump working principle

    How do peristaltic pumps work?

    Rollers in a peristaltic pump compress the tube as they rotate, creating a vacuum which draws fluid through the tube.

    Nothing but the pump tube touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. The animation shows fluid being drawn into a pump tube, trapped by the pumphead roller, and expelled when the next roller passes over the tube. As the rollers rotate, a vacuum is formed in the tube, pulling in more fluid, for the next roller pass.

    The complete closure of the tube when is it occluded (squeezed) between the roller and the track, gives the pump its positive displacement action, preventing backflow and eliminating the need for check-valves when the pump is not running.

    Why choose a Watson-Marlow sanitary peristaltic pump?

    Watson-Marlow peristaltic pumps totally contain the fluid within the tube, isolating it from any source of contamination. High performance, high purity tubing further enhances the integrity of the process.
