Overview, definition and working principle of the peristaltic pump silicone tube

Overview

The silicone tube used in peristaltic pumps is the core component of the system for liquid transportation. It is widely applied in fields such as medical, chemical, food, pharmaceutical, and laboratory industries. Due to its excellent chemical stability and biocompatibility, the silicone tube has become the most commonly used material in peristaltic pumps, capable of meeting the requirements for high-precision, small-volume fluid delivery.

Definition

A peristaltic pump silicone tube is a flexible tubing made from silicone rubber (silicone polymer), typically produced using an extrusion process with imported raw silicone materials. The inner walls of the tube are smooth and do not stick together after prolonged compression. The tube has precise dimensional tolerances, with uniform wall thickness and no eccentricity.

It is resistant to fatigue, abrasion, tearing, high rebound, and has minimal residue even after prolonged use. These features ensure that the silicone tube can repeatedly deform under compression by the pump's rollers or pressure blocks without failure, ensuring stable flow. It is used in peristaltic pumps to achieve directional flow of liquids or gases through mechanical compression.

Working Principle

The working principle of the peristaltic pump silicone tube is based on the mechanical compression mechanism of the peristaltic pump. The peristaltic pump consists of a drive motor, pump head, and silicone tube. The silicone tube is placed in the roller or pressure block system of the pump head. The motor drives the rollers to rotate, compressing the silicone tube in sequence, which creates a sealed liquid segment (referred to as a "liquid cushion") inside the tube.

As the rollers move, the liquid cushion is pushed forward, achieving unidirectional flow of the liquid. The elasticity of the silicone tube allows it to quickly return to its original shape after compression, generating negative pressure to suck in new liquid. Since the liquid only flows inside the silicone tube and does not come into contact with the pump body, contamination is avoided. By adjusting the motor speed or selecting silicone tubes with different inner diameters, the flow rate can be precisely controlled, making it suitable for micro or precise fluid dispensing.

Main Features and Performance of Platinum-Cured Peristaltic Pump Silicone Tubes

High Purity

Manufactured using platinum curing technology, there are no harmful residues, complying with pharmaceutical and food safety standards, and ensuring safe transmission of high-purity fluids.

High Temperature Resistance

Operates within a temperature range from -50°C to 200°C, resistant to steam or gamma radiation sterilization, and does not easily deform.

Corrosion Resistance

Shows good resistance to weak acids, weak bases, and alcohols, making it suitable for various chemical liquids.

Precision Extrusion

Manufactured with strict tolerances to achieve high repeatability and high-precision filling, dispensing, and metering.

Key Advantages of Peristaltic Pump Silicone Tubes

High Elasticity

Silicone tubes can withstand the repeated compression of the peristaltic pump rollers and quickly return to their original shape, ensuring stable fluid delivery.

Chemical Stability

Resistant to acids, alkalis, and corrosion, making it suitable for various chemical liquids, such as weak acids, weak bases, and alcohols.

Biocompatibility

Meets medical or food-grade standards (e.g., FDA, USP Class VI), making it safe for use in the pharmaceutical and food industries.

Temperature Resistance

Can work within a temperature range of -50°C to 200°C, suitable for fluid transmission in both hot and cold environments.

Low Adsorption

The smooth surface prevents the absorption of transmitted substances, reducing residue and contamination.

Transparent or Semi-Transparent

Allows easy observation of the liquid flow inside the tube, making it convenient for monitoring and debugging.

Wear Resistance

Capable of enduring long-term mechanical compression without shedding particles, thereby extending its service life.

Customizable Specifications

Inner diameter, outer diameter, and wall thickness can be customized to meet various flow and pressure requirements.

Main Precautions

Tubing Selection

Choose the appropriate silicone tubing type based on the nature of the fluid being transported (e.g., pH, viscosity).

Lifespan Management

Silicone tubing may wear out due to long-term compression, so it should be regularly inspected and replaced.

Cleaning and Sterilization

Silicone tubing supports high-temperature, high-pressure sterilization or chemical cleaning, and should comply with relevant standards and protocols.
