Peristaltic pump

Peristaltic pumps

The hose pump uses a peristaltic hose, through which the medium is pumped. The hose is made of plastic and is flexible.

The design ensures that the medium only comes into contact with the hose, thus protecting the medium and the pump. Since the medium only comes into contact with the hose, this makes the pump suitable for pumping aggressive, viscous and sterile liquids.

Peristaltic pumps are suitable for a very wide range of applications, but are mainly used for 'difficult' liquids with high viscosity, many solids or where high suction power is required. The pumps do not have a mechanical seal and are allowed to run dry.

Working principle peristaltic pumps

the working principle of a hose pump

Peristaltic pumps are used to pump a very wide range of applications.

The medium is moved by means of a peristaltic hose attached in the pump housing. This hose is pressed shut by a rotor which is fitted with bearing rollers. By pressing shut and opening the hose, underpressure is created, causing the hose to become full of liquid.

Subsequently, the liquid is trapped between two rollers and the liquid is forced out of the pump housing by the rotating movement. The liquid is sucked in again on the suction side, so that this process continues continuously.

Constant, pulsation-free flow

The working principle of hose pumps guarantees a constant, pulsation-free flow of liquids. In addition, the hose always remains completely closed, so that the liquid cannot flow back.

For which applications is a hose pump suitable?

  • Aggressive, corrosive, abrasive and highly viscous liquids
  • Food and beverages
  • Chemicals
  • Coatings, paint, ink
  • Glue
  • Acids
  • (Waste) water
  • Slurries
  • Cleaning agents
  • And more!

What are the properties and advantages of a peristaltic pump?

  • The direction of rotation is reversible
  • Does not have a mechanical seal
  • Suitable for both loading and unloading
  • Good dosing performance due to a very even liquid flow
  • Simple in-line cleaning
  • May run dry
  • Suitable for sensitive media
  • Self-priming
