What does a peristaltic pump do?

March 23, 2021

In the past, peristaltic pumps have been limited by low flow rates. Only a few liters of liquid can be supplied per minute. However, the successful development of the new model has significantly increased the flow rate of the peristaltic pump using large-capacity pump tubing and enhanced pump tubing. Some industrial hose pumps have a maximum flow rate of 108 gallons per minute, which can meet the needs of large flow pumps. Therefore, peristaltic pumps have become a viable choice for companies that require low maintenance costs and pollution-free pumps. Certain applications do not require inherent pulsation during peristaltic pumping. This pulsation can be reduced by increasing the number of rollers. You can also reduce this pulse by adding a pulse damper.

The peristaltic pump has the following advantages:

1. Pump tube material

The pump tube is the only part in contact with the pump fluid. Therefore, when judging the suitability of the material, you only need to find the correct pump tube material. Available pump tubing materials can be used in a variety of ways, including silicone tubing, thermoplastic tubing, Viton fluoroelastomer tubing and harder PTFE tubing. This means you can always find the most complex and difficult fluid pumping requirements. Contains the material of the pump tubing.

Peristaltic pumps are suitable for pumping various liquids, from sensitive cell cultures to industrial solvents. The same pump can be used multiple times. Only the pump tubing should be replaced.

2. Smooth pumping process

The design and structure of the peristaltic pump can produce a soft compression effect to discharge fluid comfortably. The fluid is not mechanically ground or sheared through gears, valves or other parts, so that the solid parts (such as cell walls and particles) in the fluid are intact. Therefore, the peristaltic pump is particularly suitable for transporting sensitive liquids, slurries or suspended solids. In addition, since the moving part is separated from the fluid, the abrasion of the fluid can be prevented.

3. It can pump various liquids.

In addition to providing sufficient self-absorption pump capacity, the vacuum generated by the peristaltic pump is sufficient to pump most viscous fluids. For peristaltic pumps, many viscous fluids that are difficult to pump with other types of pumps are not a problem. Most manufacturers have established various specifications for peristaltic pumps, including the pumping of mucosal fluid. Some pumps can only supply liquid. This is because the liquid heat is released and used to lubricate moving parts. Peristaltic pumps can transport liquids, gases and multiphase mixed fluids. If there are bubbles in the fluid (such as gas released from the solution), the bubbles will be released with the liquid without blocking. Therefore, the peristaltic pump can run dry without damage.

4. High operating efficiency

The work efficiency of the peristaltic pump is very high. These advantages are especially obvious when transporting corrosive chemicals. In this case, different types of pumps must be treated with chemical resistance to several waterproof components. If you need to pump, transport or distribute these chemicals, it is wise to buy a peristaltic pump with chemically compatible pump tubing instead of a pump with expensive special parts.

You only need to replace the pump tube to pump multiple solutions with the same pump. You can use the same pump for multiple purposes without having to purchase multiple dedicated pumps. Compared with other types of pumps, it also reduces labor and maintenance costs. Reduce the total cost of use while expanding the application.

Peristaltic pumps has many advantages and advantages, but they also have their limitations. The soft pump uses flexible pump tubing, so the pressure it can withstand is limited. As the pressure in the tube increases, the pump tube expands outward, compressing the rollers, causing wear. The pump tube may rupture under high pressure and threaten the safety of nearby personnel. However, technological advances have led to the next generation of flexible pump tubing that can withstand the high pressure expansion trend.
