Key Considerations When Choosing Silicone Tubing for Peristaltic Pump

Understanding silicone tubing for peristaltic pump

Silicone tubing for peristaltic pump is made of high-purity imported silicone rubber raw materials, platinum sulfide vertical extrusion molding, with a smooth inner cavity that can withstand long-term compression without sticking to the inner wall. With precise size tolerance, uniform wall thickness, high wear resistance, tear resistance, and resilience, it meets food hygiene, medicine, and medical testing standards.

What aspects should be noted when selecting silicone tubing for peristaltic pump?

Chemical compatibility

When selecting silicone tubing for peristaltic pump for pumping corrosive fluids, the key is to choose the correct tubing. Choosing the wrong tubing can cause danger, possibly damaging equipment or endangering personal safety. Before using new or ungraded chemicals, pump tests must be performed. Dip a small section of tubing into the fluid, checking for changes in the size, color, weight, and strength of the silicone tubing for peristaltic pump. If possible, test the tubing in the pump before stretching it. When the tubing is crushed during compression, the chemical substance is kneaded into the wall of the tubing, accelerating the aging and disintegration of the tubing.

Non-polluting

In many applications, such as laboratory research, pharmaceutical, and biotechnology product production, it is essential to isolate the fluid. Numerous studies have shown that silicone tubing for peristaltic pump and silicon-based materials do not react chemically with various biological materials.

Anti-bending ability

Different tubings have varying abilities to withstand repeated rolling by rollers. The combination of specific tubing size, tubing material, pump head type, and operating speed determine the tubing's service life. The service life of silicone tubing for peristaltic pump, or the bending yield limit in the pump, is the first consideration before putting it into use. Choosing tubing with higher anti-bending ability, using thicker tubing walls, selecting larger pumps, and using lower operating speeds can maximize the tubing's service life.

Clarity

For some applications, such as gaining a clear understanding of the pumping or dry running process, it is very valuable to be able to observe the fluid's movement through the pipeline. However, from another perspective, opaque tubing is beneficial to some photosensitive fluids.

Hardness meter

The tubing wall hardness is critical in determining a specific pipeline's pumping capacity. If the silicone tubing for peristaltic pump is too soft, it is easy to break; if it is too hard, the pump cannot work. A hardness meter can be used to determine the physical properties of a particular tubing material.

Fluid pressure

Fluid pressure usually constrains the ability of tubing to transport pressure fluids. Most peristaltic pumps use unsupported pipelines. The pressure limit of these tubes is 2 to 3 bars (30 to 45 psi). Some larger pumps on the market use supported pipelines.
