Can a Peristaltic Pump Hose Be Used With All Types of Fluids?
The short answer: No. A peristaltic pump hose relies on material compatibility to function safely. Using the wrong hose with a fluid leads to damage, leaks, or contamination. Here’s what you need to know.
Core Limitation: Material vs. Fluid Interaction
Peristaltic pump hoses are made from specific materials like silicone, PTFE and EPDM. Each material reacts differently to fluids. For example, basic rubber hoses degrade quickly with acids or solvents. Silicone hoses, while food-safe, fail with petroleum-based fluids. Even reinforced peristaltic pump hoses can’t handle every substance. For example,abrasive slurry needs specialized wear-resistant materials.
Common Fluid Types and Matching Hoses
Corrosives
Use PTFE or fluoropolymer peristaltic pump hoses. These resist chemical attacks.
Food/Pharmaceuticals
Opt for FDA-approved silicone or EPDM hoses. They avoid tainting fluids.
Abrasive Slurries
Choose reinforced peristaltic pump hoses with synthetic cord. They withstand particle wear.
High-Temp Fluids
Select Orientflex or heat-resistant silicone hoses. They retain elasticity at high temps.
Critical Precaution: Always Verify Compatibility
Never assume a peristaltic pump hose works with your fluid. Check the manufacturer’s chemical resistance chart. Test small batches first for specialty fluids. Mismatched hoses cause costly downtime, leaks, or product contamination. So compatibility checks are non-negotiable.
