Why Choose a Peristaltic Pump?
  • Accurate for metering
  • Best suction lift
  • Handles high viscosity
  • Handles large solids
  • No valves to clog or stick
  • One wearing part
  • Runs dry

Pedigree

The L range of Peristaltic Pumps operates on the peristaltic principle which was patented some 75 years ago.

The technical classification for its pumping action is known as positive displacement. This means that a fixed and known amount of fluid is discharged per revolution of the pump, with flow independent of discharge head.

How does it do that?

The workings of a peristaltic pump are simple, consisting of only one relatively low speed rotating element known as a rotor, which generally has two fixed shoes or in our case two rotating rollers, attached and spaced 180 degrees apart. The heart of the pump is the stationary hose, which is compressed on the outside of its diameter as the rotor turns and this compressing action, along with the hose springing back and refilling with product creates the pumping action. The pumped product is not touched by the rotor it is squeezed smoothly from the outside of the hose without interference and this allows the pump to handle a great variety of liquids including hazardous and or shear sensitive.
