In the former pieces, we learned the factors that you should focus on when choose a peristaltic pump hose. While in this piece, let me introduce you the last 2 factors.
The size has a direct impact on the flow rate. Thus you should focus on the diameter and wall thickness. The ID determines the flow rate. While the wall affects the rebound resilience. It also has a great influence on the lifespan.
If the hose size is too small for the pump head, the pump head may not be able to hold the hose firmly. Or it will reduce the flow. If the hose is oversized, it will cause over wear and earlier failure. In general, the more precise the pump system is, the higher the demand to size will be. At the same time, the viscosity of the fluid and particle will further affect the size.
Hoses has various of wear ability. While the life spans are also various. The service life is called flexible life in the pump system. Thus a flexible and thick wall hose has longer service life.
Of course, in the use, the hose life is also affected by factors such as temp, pressure, medium and corrosion. Then you should choose it based on your work conditions.
At the same time, the hose is a consumable material. With the time goes on, it will wear and tear. Once damaged, it will affect the accuracy. What;s more, it will cause fluid leakage. Then cause pump broken and safe risk. Therefore, you have to check and replace the hose regularly.
Usually, peristaltic pumps need to work for a long time. Thus the durability is really matter.
