A peristaltic pump, also known as a hose pump or dosing pump, is a device that transports fluids by alternately compressing an elastic tube. Its operating principle is similar to the peristaltic movement of the human intestine: rollers or shoes squeeze the tubing, pushing the liquid forward. With advancements in drive technology, tubing materials, and intelligent control, peristaltic pumps have evolved from laboratory equipment to industrial applications, widely used in medical, pharmaceutical, food, and chemical industries.
How It Works
A peristaltic pump consists of a drive unit, pump head, and flexible tubing. The motor drives rollers to compress the tubing in sequence, forcing fluid out; when the rollers release, the tubing rebounds, drawing in new liquid. This positive displacement mechanism ensures accurate flow control without valves, preventing backflow.
Advantages of Peristaltic Pumps
1.Clean and Contamination-Free Transfer: Fluid only contacts the tubing, reducing contamination risks—ideal for high-purity applications.
2.Gentle, Low-Shear Handling: Minimizes damage to sensitive substances like cells and polymers.
3.High Accuracy and Steady Flow: Flow rate error can be controlled within ±1%.
4.Strong Self-Priming and Bidirectional Flow: Excellent suction capability and reversible operation.
5.Simple Structure, Easy Maintenance: The only wear part is the tubing, which is easy to replace.
6.Handles Particles and Viscous Fluids: Suitable for fluids with solid particles or high viscosity.
Typical Applications
• Medical and Pharmaceutical: Infusion systems, reagent delivery.
• Food and Beverage: Filling juices, sauces.
• Chemical and Environmental: Corrosive solvents, wastewater treatment chemicals.
• Laboratories: Titration, chromatography, cell culture.
• Agriculture and Semiconductors: Nutrient solution dosing, high-purity reagent transfer.
Technological Trends
Advancements in tubing materials, intelligent monitoring, low-pulsation designs, and customized solutions will drive broader applications of peristaltic pumps.
