Food grade silicone tube can be used as peristaltic pump silicone tube?

Food grade silicone tube and peristaltic pump silicone tube belong to food grade hose,they are made of raw material silicone rubber.Food-grade silica gel tube is made of food-grade silica gel raw materials,which can be made into food-grade silica gel tube in accordance with or to reach the national food certification.But peristaltic pump silicone tube is not the same,it uses high purity silica gel raw material,platinum vulcanization extrusion molding,high transparency and scalability,can ensure that repeated extrusion can rebound,rebound rate of more than 96%.

Although some food-grade silica gel tube can also have a certain resilience,but it is certainly not good performance of raw materials dedicated to peristaltic pump silica gel tube.Food-grade silica gel tube and peristaltic pump silica gel tube,in addition to strict requirements on raw materials,the specifications and sizes of the hose themselves are also very strict.

Due to the working principle of the peristaltic pump silicone tube,the size requirements of the inner diameter and wall thickness are very accurate.Otherwise,the flow rate of the peristaltic pump silicone tube when conveying materials will be affected,thus affecting the overall production.Peristaltic pump silica gel tube also needs to have good performance,peristaltic pump silica gel tube to continue to operate for dozens of hours in a continuous working environment without damage,so food grade silica gel tube is not equipped with such characteristics.

Peristaltic pump is composed of driver,pump head and hose.Peristaltic pump hose is the main working part of peristaltic pump,its performance directly affects the accuracy and stability of peristaltic pump flow.As a flexible moving part,the hose has a certain service life and needs to be replaced regularly.There are many factors that affect the life of peristaltic pump hose,the main factors are the running speed of pump head,the material of hose and the pressure tube gap between the pump head roller and the arc.

General peristaltic pump hose life depends on speed,outlet pressure,hose material and chemical compatibility,standard peristaltic pump hose life is about 200-300 hours,the lower the speed,the longer the hose life.If the hose life has higher requirements,you can choose some peristaltic pump hose,hose life can reach more than 1000 hours.

In the selection of peristaltic pump should pay attention to the need to transport the liquid will not corrosion pump pipe.Because the pump tube has many materials and many types of liquid,no pump tube can withstand all the liquid,so we need to confirm our liquid type and make comparison through chemical phase dissolution table or through immersion experiment to ensure that the pump tube can be used.
