Peristaltic pump is popular due to their pollution-free and the low maintenance. However, many people often overlook an important part, the peristaltic pump hose. In fact, the quality of peristaltic hose has a huge impact to the pumping work. Then next, let me introduce you several factors that affect the performance of peristaltic pump hoses.
Corrosion resistance
When transporting different fluids, the hose should show certain excellent chemical property. While this is what we know as chemical compatibility. Such as: low adsorption, good temp resistance, not easy to age, not swelling, corrosion resistance, etc.
Resistance to chemical corrosion decreases with increasing temp. Chemicals that have no effect at room temp may have an effect as the temp increases.
Pressure
Peristaltic hose has a pressure limit. So if the system pressure exceeds the limit, the hose will expand. Then it will cause excessive wear or rupture. Material, diameter and wall thickness can affect the pressure.
Temp
You should consider the working temp range of the hose. While material determines the temp resistance.
Size
The size of the hose has a direct impact on the flow rate. The inner diameter determines the flow rate. While the wall thickness affects the rebound property and the lifespan.
Certificate
Hoses should have certifications when used for related purposes. Such as USP, EP, FDA, USDA and the NSF.
Flexibility, elasticity and service life
The service life in the pump system is called flexible life. In a specific app, the features of the pump are very consistent. Choose thick wall pipe with a high flow pump and run at a lower speed to get a longer hose life.
