How to Choose Peristaltic Pump Tubing? 7 Key Factors for Proper Selection
Introduction
When selecting a peristaltic pump system, many users focus on pump performance while overlooking one of the most critical components—the tubing.
In reality, tubing material directly affects:
Pump performance
Service life
Flow accuracy
Chemical compatibility
Maintenance costs
Choosing the wrong tubing material can result in premature failure, unstable flow rates, contamination, and increased downtime.
This guide explains how to select the right peristaltic pump tubing for your application.
1. The fluid being transferred determines the tubing material.
Chemical compatibility should always be the first consideration.
Common fluids include:
Water-based liquids
Acids and alkalis
Chemical reagents
Food and beverages
Pharmaceutical fluids
Viscous media
Understanding the fluid's chemical properties, concentration, temperature, and viscosity is essential for proper tubing selection.
2. Silicone tubing is ideal for food and pharmaceutical applications.
Silicone tubing offers excellent flexibility and biocompatibility.
Key benefits include:
Non-toxic and odorless
High transparency
Excellent flexibility
Wide temperature range
Typical applications include:
Food processing
Beverage production
Pharmaceutical manufacturing
Biotechnology systems
Platinum-cured silicone tubing is often preferred for high-purity applications.
3. PharMed® tubing is suitable for long-life continuous operation.
Continuous-duty applications require tubing with excellent fatigue resistance.
PharMed tubing provides:
Long pump life
Stable flow performance
Excellent durability
It is commonly used in:
Biopharmaceutical processing
Fermentation systems
Continuous manufacturing operations
4. Fluoroelastomer tubing is suitable for aggressive chemicals.
Chemical processing applications often require specialized tubing materials.
Typical fluids include:
Strong acids
Strong alkalis
Organic solvents
Laboratory chemicals
FKM and other chemical-resistant materials provide superior compatibility and longer service life.
5. Temperature resistance directly affects tubing performance.
Operating temperature is a critical selection factor.
Typical temperature ranges:
Material
Temperature Range
Silicone -60°C to 200°C
PharMed -50°C to 135°C
FKM -20°C to 200°C
Excessive temperatures can significantly reduce tubing life.
6. Tubing life is essential for reducing maintenance costs.
Peristaltic pump tubing is continuously compressed during operation.
Therefore, fatigue resistance directly affects:
Replacement intervals
Downtime
Operating costs
Selecting long-life tubing can significantly improve system efficiency.
7. Choosing an experienced tubing supplier is equally important.
Different industries have different requirements.
Food Industry
Key requirements:
FDA compliance
Non-toxic materials
Easy cleaning
Pharmaceutical Industry
Key requirements:
USP Class VI compliance
Biocompatibility
Low extractables
Chemical Industry
Key requirements:
Chemical resistance
Long-term durability
