How to choose a suitable peristaltic pump hose?

Choosing a suitable peristaltic pump hose is an important step in ensuring the normal operation of the peristaltic pump. The peristaltic pump hose is an important component of the peristaltic pump, and its quality and rationality of selection will directly affect the performance and lifespan of the peristaltic pump.

Choosing a suitable peristaltic pump hose requires considering the following aspects:

1. Material of peristaltic pump hose: The materials commonly used for peristaltic pump hoses include chloroprene rubber, silicone rubber, polytetrafluoroethylene, etc. Different materials have different corrosion resistance, wear resistance, and high temperature resistance. According to the requirements of the working environment and medium, select suitable hose materials to ensure that they can withstand factors such as corrosion, wear, and temperature of the medium.

2. Wall thickness of peristaltic pump hose: The wall thickness of the hose affects its pressure resistance and service life. Reasonable selection of wall thickness can improve the compressive strength and wear resistance of hoses, and extend their service life. However, excessive wall thickness can also increase the stiffness of the hose, affecting its flexibility and drainage capacity. Reasonably select the wall thickness of the hose according to specific needs.

3. Inner diameter and outer diameter of peristaltic pump hose: The inner diameter and outer diameter of peristaltic pump hose determine the flow and pressure capacity of the hose. The selection of the inner diameter of the hose should be based on the required flow rate and the viscosity of the medium. Generally speaking, hoses with smaller inner diameters are suitable for conveying medium with lower viscosity, while hoses with larger inner diameters are suitable for conveying medium with higher viscosity. At the same time, the outer diameter of the hose should also consider the size of the pump head and connecting components to ensure that the hose can connect and adapt to the pump head and pipeline system.

4. Connection method of peristaltic pump hose: The connection method of the hose includes threaded connection, flange connection, clamp connection, etc. Different connection methods are suitable for different working environments and media characteristics. Choosing the appropriate connection method can improve the pressure resistance performance and connection reliability of the hose.

5. Supplier selection for peristaltic pump hoses: Choose reputable and experienced peristaltic pump hose suppliers to ensure the quality and performance of the hoses. You can choose a suitable supplier by consulting the supplier's website, consulting other users' evaluations, and evaluating the supplier's production capacity and quality management system.
