Peristaltic pump hose basics

Release date:May 18, 2023 Source:PreFluid Pageviews:-
Peristaltic pump hose is an accessory of peristaltic pump, mainly used to transport liquid, gas, liquid and a mixture of gas and solid.
Peristaltic pump hose is an accessory of peristaltic pump, mainly used to transport liquid, gas, liquid and a mixture of gas and solid. The peristaltic pump hose has a certain elasticity, a certain wear resistance, a certain ability to withstand pressure, no leakage (good air tightness), low absorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, low precipitate characteristics.

Functional features:

Micro transparent, tasteless, non-toxic, anti - bacteria

The inner wall is bright and not easy to attach particles

It can be disinfected under vacuum high temperature and high pressure

Can not be used in high concentration acid base, organic solvent and oil

Hose material:

Silicone rubber, fluorine rubber, Teflon, rubber, plastic, synthetic materials, different materials show different properties, have different uses.

Selection method:

Corrosion resistance/compatibility

When transferring different fluids, the hose should show certain excellent chemical properties, which is called chemical compatibility. Such as: low adsorption, good temperature resistance, not easy to aging, swelling, corrosion resistance, low precipitates

Chemical corrosion resistance decreases with the increase of temperature. Chemicals that have no effect on the pipe at room temperature may affect the hose with the increase of temperature.

pressure

The application of peristaltic pump is limited by the bearing capacity of the hose.

If the system pressure exceeds the limit of the hose pressure, the hose will expand, resulting in excessive hose wear or hose rupture.

The factors affecting the pressure of the hose are: material, diameter and wall thickness ratio, etc.

temperature

The adaptability of the hose to the operating temperature range is a consideration for the user. Different materials have different temperature behavior.

dimension

Hose size has a direct impact on the flow rate. Good pump design takes into account the inner diameter and wall thickness of the applicable hose, matching the optimal hose size or tube number range. The inner diameter of the hose determines the flow rate; Wall thickness affects the ability of the hose to be compressed and rebound, and also has a great influence on the life of the hose.

certification

Hoses used for related purposes may be subject to relevant certification. Such as United States Pharmacopoeia standard USP, European Pharmacopoeia standard EP, United States Food and Drug Administration Standard FDA, United States Department of Agriculture standard USDA and National Health Foundation standard NSF.

Flexibility/elasticity/life

Different hose resistance roller repeated extrusion, friction ability is different. Different types of pipe, pipe, pump head, running speed have different life. Service life in pump systems is called flexible life, in particular applications, pump characteristics are very consistent. Choose long life, thick wall pipe, choose large flow pump, running at low speed can obtain longer hose service life.
