INDUSTRY COMPONENT

Tube (for peristaltic pumps)

Flexible tubing for peristaltic pumps that transfers fluids via compression cycles without contamination.

Component Specifications

Definition

A specialized elastomeric tube designed for peristaltic pumps, where rotating rollers or shoes compress the tube to create a moving occlusion that propels fluid through the system. This design ensures the fluid only contacts the tube interior, making it ideal for sterile, abrasive, or corrosive applications where contamination must be avoided.

Working Principle

Operates through cyclic compression by pump rollers, which sequentially squeeze the tube to create a peristaltic wave that pushes fluid forward while maintaining complete separation between the fluid and pump mechanics.

Materials

Typically made from silicone, thermoplastic elastomers (TPE), fluoropolymers (like PTFE), or natural rubber, selected based on chemical compatibility, flexibility, and durability requirements.

Technical Parameters

Inner Diameter 1-50 mm
Shore Hardness 40-80 A
Wall Thickness 1-10 mm
Pressure Rating Up to 100 psi
Temperature Range -50°C to 200°C

Standards

ISO 13485, DIN 11864

Frequently Asked Questions

How often should peristaltic pump tubes be replaced?

Replacement intervals depend on material, fluid type, and operating conditions; typically every 200-1000 hours to prevent fatigue failure.

Can these tubes handle abrasive fluids?

Yes, with materials like reinforced silicone or specialized polymers, but wear rates increase, requiring more frequent replacement.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
