The popularity of peristaltic pumps can be attributed to their design. The design uses a motor to drive a set of rollers for rotation. The rollers are successively milled through a flexible pump tube for repeated compression and release. This squeezing creates a vacuum that draws in the fluid and through the pump tube to complete the pumping process. Because only the pump tube is a water-passing component, the maintenance and cleaning of such a pump is simple and convenient.
This design brings several benefits, making the peristaltic pump suitable for a variety of complex and difficult applications. The advantages of this * are:
l no pollution
l Easy to operate
l rarely maintained
l Self-priming ability
l A variety of pump tube materials can be used
l gentle pumping process
l Pumpable liquid, gas, multiphase mixture and viscous fluid
l High operating efficiency
No pollution
The peristaltic pump is designed in such a way that the delivered fluid always flows within the pump tubing. This is very important for two reasons: first, the fluid does not contaminate the pump; second, the pump does not contaminate the fluid. This is an advantage when delivering chemically corrosive fluids or high purity fluids. Since the fluid does not touch the gears, sealing elements, diaphragm elements, or other moving parts, selecting a chemically compatible pump for a particular solution is as simple as selecting a pump tube that is chemically compatible with the solution. Just fine.
Since only the pump tube is a water-passing part, there is no need to worry about corrosion, wear and loss of other parts. Therefore, a peristaltic pump is an ideal solution when transporting abrasive fluids. Other types of pumps are susceptible to wear when moving such fluids, resulting in frequent replacement of the components and increased component failure.
Peristaltic pumps have also been successfully applied to deliver solutions with a tendency to settle or harden. In this case, it is not necessary to completely disassemble the parts for cleaning, just rinse or replace the pump tube.
Peristaltic pumps are also widely used in a number of chemical processes that require high standards, maintain sterility and prevent contamination. Most pump tubing types can easily withstand common **** processes such as high pressure** treatment, gamma radiation** treatment, or ethylene oxide gas** treatment. Most systems accept the on-site fumigation** (SIP) and on-site cleaning (CIP) processes. This guarantees the completeness of the entire pump system, and for those ordinary pumps that are time-consuming and labor-intensive, the peristaltic pump has become an attractive alternative.
Easy to operate
The operation of the peristaltic pump is very simple, and many pumps can be used out of the box. Some models are equipped with interchangeable pump heads that can be installed in a few minutes by hand screwing. The development of engineering technology has spawned a new design configuration that shortens the time required to replace the pump tube to a few seconds. In addition, most pumps are easy to control, use the dial pad or keypad to control the speed, and program the more complex tasks through an intuitive menu.
Rarely maintained
Most peristaltic pumps maintain good working conditions with minimal maintenance. The pump tubing must be replaced periodically to prevent leakage or flow reduction. The replacement process typically takes only a few seconds, which is an advantage when using the same pump to deliver or dispense different chemical solutions. After changing the solution, you only need to replace the pump tube. It takes only a few minutes to restart and start the pump, saving time and labor. Moreover, the same pump can be used in different chemical processes, resulting in significant cost savings.
In addition to the need to replace the pump tubing, the peristaltic pump requires minimal maintenance. For pumps that are driven by a brush motor, the brushes should also be replaced periodically. It is usually changed every 3,000 hours or so. Many pumps are designed with a high degree of protection. After the dirty liquid is delivered, the pump tube can be removed for quick and thorough cleaning.
Because only the pump tube is a water-passing component, the peristaltic pump does not release the wear and damage of moving parts common to other pumps. This eliminates the expense of frequent replacement of related components, the labor required for maintenance and repair, and the costly downtime caused by component failures.
Self-irrigation ability
At start-up, the peristaltic pump produces enough suction to draw liquid from the liquid source into the pump tubing, eliminating the need for pre-fill pump and suction tube filling. This also eliminates the need to flood the water, so it is no longer necessary to place the pump below the level of the liquid source, making the pump installation location flexible and allowing the pump to move freely. In addition, the peristaltic pump will not lose water, so it can avoid unnecessary stoppage.
Pump tube material
Since the pump tubing is a mere component that is in contact with the fluid being pumped, when determining material compatibility, simply find the correct tubing material. The pump tubing can be used in a wide range of materials, including silicone tubing, thermoplastic tubing, Viton fluoroelastomer tubing, and even more rigid Teflon tubing, which means you can always find a pump that meets the needs of complex and difficult fluids. The pump tube material comes.
Many pump tubing types also meet the requirements of USP, FDA, USDA, and/or NSF authorities. This allows the peristaltic pump to be adapted to pump a variety of fluids, from sensitive cell culture fluids to industrial solvents, and also allows the same pump to be used in a variety of applications - just replace the pump tubing.
Soft pumping process
The design of the peristaltic pump produces a gentle squeezing action that pumps the fluid out soothingly. The fluid does not mechanically grind or shear any gears, valves or other components, leaving solid components in the fluid, such as cell walls and particles, intact. Therefore, peristaltic pumps are particularly suitable for transporting sensitive fluids, slurries or suspended solids. In addition, the moving parts are separated from the fluid to protect them from abrasion by fluids.
Can pump a variety of fluids
In addition to having sufficient self-priming pump capacity, the vacuum created in the peristaltic pump is sufficient to pump most of the viscous fluid. Many viscous fluids that are difficult to pump with other types of pumps are not a problem for peristaltic pumps. Most manufacturers have developed various indicators for their peristaltic pumps, including pumping viscous fluids.
Some pumps can only deliver liquids because they are used to dissipate and lubricate moving parts. The peristaltic pump delivers liquid, gas and multiphase fluids. If bubbles appear in the fluid (for example, from the gas released in the solution), simply pump them together with the liquid portion without blocking. Therefore, the peristaltic pump can be operated dry without damage.
High operational efficiency
Peristaltic pump operation is very efficient. This advantage is especially noticeable when transporting corrosive chemicals. In this case, other types of pumps require chemical resistance to their multiple water-passing components. When pumping or transferring or distributing such chemicals, it is wise to buy a peristaltic pump with a chemically compatible pump tube instead of a pump with expensive, special parts.
Simply replace the pump tubing and pump the different solutions with the same pump. The same pump can be used for a variety of purposes without the need to purchase several dedicated pumps. In addition, it consumes less labor and lower maintenance costs than other pumps. While expanding the application area, it reduces the total cost of use.
limitation
Although peristaltic pumps have many advantages and benefits, they have their limitations. Because the peristaltic pump uses a flexible pump tube, it can withstand limited pressure. As the pressure inside the tube increases, the pump tube bulges outward and squeezes the roller to cause wear. The pump tube can burst under higher pressure, which may endanger the safety of the surrounding people. However, technological advances have spawned a new generation of flexible pump tubing that resists the tendency of inflation due to high pressure.
Peristaltic pumps have historically been subject to their lower flow rates: only a few liters of fluid can be delivered per minute. However, with the successful development of the new model, the large-diameter pump tube or the reinforced pump tube was used, and the flow rate of the peristaltic pump was significantly increased. Some industrial hose pumps have a large flow rate of 108 gallons per minute to meet the needs of high flow pumps. Therefore, the peristaltic pump becomes a viable replacement for companies with no pollution and low maintenance pumping requirements.
Some applications do not expect inherent pulsation during peristaltic pumping. This pulsation can be reduced by increasing the number of rollers. Adding a pulse damper can also help reduce this pulsation.
in conclusion
Compared with the past, peristaltic pumps have been increasingly recognized in more and more applications and industries. Its application has evolved from being only found in laboratories to becoming a critical and reliable component of many industrial processes.
The wide application and ease of use of peristaltic pumps make it possible to meet a variety of complex and difficult fluid delivery needs. As the demand for pumps continues to grow worldwide, the future of peristaltic pumps will be limitless.
Application introduction and advantage analysis of peristaltic pump
Peristaltic pumps are one of several types of growth in the positive displacement pumps on the market. However, many people are still not familiar with the technical principles and advantages of such pumps. A peristaltic pump is also known as a pump tube pump. In the past, this pump was used almost exclusively in laboratories. However, after redesigning, the flow rate and pressure of the pump have been improved. A large number of peristaltic pumps have now been successfully used in chemical process control and production.
