A PERISTALTIC PUMP IS A TYPE OF POSITIVE DISPLACEMENT PUMP.
These pumps are sometimes referred to as Roller pumps, Tube pumps or Rotary Pumps which are all very appropriate names. The very simple design consists of a flexible tube in a ‘C’ shape in which the fluid is squeezed along it by a rotating spoke assembly.
The LSM Pumps use rollers for better performance and prolonged service life.
In front of each roller, pressure builds up and because of the hose’s elasticity a vacuum builds up behind the roller. The pressure pushes the fluid out of the hose and the vacuum sucks the new fluid in. This positive displacement action creates a pulsating flow which whilst typically delivering a slower flow rate than centrifugal pumps, its steady action handles very thick (highly viscous) fluids. Its gentle force lends it well to liquids and pastes that have properties that would be damaged by rapid churning. Another advantage is that this pump type can safely run dry, whereas most other pumps can overheat if left running without a supply of liquid.
Drawbacks of the peristaltic include the pressure loss between pulses which equates to reduced head pressure capabilities. However, this is rarely a practical issue on typical peristaltic applications and if large volumes of slurry or liquid need elevating to height then a centrifugal is likely to be the answer.
Peristaltic pumps are used in a wide range of industries and applications such as food, mining, chemical, fishing and agriculture as well as on and off shore, in anaerobic digestion / biogas and in the production of concrete and paint.
The benefits of using peristaltic pumps
- The liquid never coming into contact with any moving part therefore totally removing the risk of contamination
- Very low energy usage
- Few wear parts mean lower maintenance costs, saving you money
- The ability to run dry
- The ability to handle a wide variety of materials including solids
