The peristaltic pump hose is a core component of peristaltic pumps—it directly impacts pump efficiency, lifespan, and the purity of the pumped medium. Choosing the right one matters, and it’s not just about picking the highest-performance option. Instead, you need to balance performance and cost.
An ideal peristaltic pump hose should resist pressure and corrosion, plus stand up to aging. With this in mind, Orientflex recommends three top peristaltic pump hose materials for different needs.
1. Silicone Peristaltic Pump Hose
Silicone peristaltic pump hoses have a main chain of silicone rubber, made from alternating silicon and oxygen atoms. They offer strong resistance to high temperatures, low temperatures, and oil—key traits for many applications.
This type of peristaltic pump hose is widespread in the biopharmaceutical industry. Manufacturers typically cure it in two ways: platinum cure and peroxide cure. While silicone peristaltic pump hoses cost more than other options, their smooth inner walls reduce fluid resistance. This boosts pumping efficiency significantly.
2. Fluororubber Peristaltic Pump Hose
Fluororubber peristaltic pump hoses excel at corrosion resistance. This makes them the top choice for transporting highly corrosive media and non-polar solvents.
That said, fluororubber peristaltic pump hoses have drawbacks: they lack flexibility and aren’t very wear-resistant. They also come with a higher price tag. Even so, they’re irreplaceable in industries that handle aggressive chemicals.
3. PTFE Peristaltic Pump Hose
PTFE peristaltic pump hoses (also called Teflon peristaltic pump hoses) offer exceptional chemical stability. They resist a wide range of substances, tolerate extreme temperatures, and have a low friction coefficient.
But PTFE peristaltic pump hoses have a major downside: poor flexibility. They’re prone to breaking if bent too sharply. For this reason, you must weigh their strengths against their weaknesses when selecting this type.
