Peristaltic Pump

A peristaltic pump is a type of positive displacement pump that uses a flexible tube to pump fluids. It works by compressing the tube, creating a pressure wave that propels the fluid forward.

How it works:

1. Tube Compression: A series of rollers or shoes compress the flexible tube.
2. Fluid Displacement: As the tube is compressed, the fluid is forced to move forward.
3. Tube Relaxation: The tube relaxes, creating a vacuum that draws in more fluid.

Key Advantages:

• Gentle Pumping: The peristaltic action is gentle, making it suitable for delicate fluids.
• No Contamination: The fluid only contacts the inner surface of the tube, minimizing contamination.
• Precise Flow Control: By adjusting the pump’s speed, precise flow rates can be achieved.
• Versatile: Can handle a wide range of fluids, from thin liquids to viscous slurries.
• Self-Priming: Can pump fluids from a reservoir below the pump level.
• Low Maintenance: Simple design with minimal moving parts.

Applications:

• Laboratory Applications: Dispensing precise volumes of liquids, transferring samples, and feeding reagents.
• Pharmaceutical Industry: Transporting sensitive drugs and chemicals.
• Food and Beverage Industry: Pumping food products like sauces, syrups, and dairy products.
• Biotechnology: Transferring cell cultures and other biological materials.
• Chemical Processing: Handling corrosive and hazardous fluids.
• Medical Applications: Infusing fluids and medications.

Types of Peristaltic Pumps:

• Roller Pumps: Use rollers to compress the tube.
• Shoe Pumps: Use shoes to compress the tube.
• Linear Peristaltic Pumps: Use a linear motion to compress the tube.

By understanding the principles of peristaltic pumps, you can select the right pump for your specific application and ensure efficient and reliable fluid transfer.
