Peristaltic Pumps

Peristaltic pumps, often referred to as ‘roller pumps', are a type of positive displacement pump that can be used for moving a variety of different fluid types smoothly and consistently around a closed system.

How do peristaltic pumps work, and how do they differ from other pumps?

  • Peristaltic pumps are so-called because they work using a process known as peristalsis, which denotes a process of alternating compression and relaxation being used to move fluids along through a tube or pipe
    • This is essentially the same process that our bodies use whenever we swallow and digest food!
  • Peristaltic pumps work by housing a dual set of rollers inside the main chamber of the pump, which rotate on a mounted shoe or disk
  • The robust but flexible tubing through which the liquid is being carried loops around the outside of this shoe, such that the rollers make contact with it as they rotate through 360 degrees, alternately compressing and relaxing the flexible walls of the tubing at various points
    • This means that the tube containing the fluid is continually being squeezed and released at two or key points inside the main body of the pump
  • The end result of this process of alternately sealing and opening the diameter of the tubing is the creation of small pockets of vacuum pressure, which is ultimately what works to draw the fluid along the tube

The design of peristaltic pumps means that none of the fluid being drawn through the pump mechanism ever comes into direct contact with any of the pump's moving parts.

Furthermore, a peristaltic pumping action makes these pumps well-suited to applications that require accurate dosing - as such, many models of peristaltic pump can either be left to run continuously, or set to perform timed partial revolutions in order to deliver smaller quantities of pumped fluid at predictable intervals.
