How to Avoid Fuel dispenser hoses accidents
Peristaltic pump hoses serve as one of the core components of a peristaltic pump. They are crucial for the pump’s operation. In fact, they directly affect three key things: the pump’s efficiency, the pump’s service life, and the purity of the transported medium.
First, we need to clarify one point: selecting materials for pump hoses isn’t just about choosing the highest-performance option. Instead, you need to find a balance between performance and cost. An ideal pump hose should meet three basic requirements: it resists pressure, it resists corrosion, and it doesn’t age easily. On this basis, we at Everflex recommend three types of peristaltic pump hoses.
1. Silicone Tube
The silicone tubes used in peristaltic pumps have a main chain made of silicone rubber. This rubber consists of alternating silicon and oxygen atoms. Silicone tubes have three high-quality properties: strong resistance (to heat, cold, etc.), low resistance (to fluid flow), and oil resistance.
They are one of the most common tubes in the biopharmaceutical industry. Manufacturers generally use two treatment methods for them: platinum cure and peroxide cure. Silicone hoses cost more than hoses made of other materials. But their inner walls are smooth. This smoothness reduces fluid resistance, which in turn improves pumping efficiency.
2. Fluorine Rubber Tube
Fluorine rubber pipes have excellent corrosion resistance. For this reason, they are the best choice for transporting highly corrosive and non-polar solvents. However, this type of hose has two drawbacks: it isn’t very flexible, and it has poor wear resistance.
Despite its higher cost, fluorine rubber hose remains irreplaceable in certain industries. These industries rely on its corrosion resistance to handle harsh fluids safely.
3. PTFE Tube
PTFE hose offers three excellent traits: strong chemical stability, good temperature resistance, and a low friction coefficient. However, PTFE hose (also called Teflon hose) has obvious downsides: they have poor flexibility, and they break easily.
Therefore, when choosing a PTFE tube, you need to carefully weigh its advantages against its disadvantages. Make sure its strengths match your specific usage needs.
