Peristaltic Pump

A peristaltic pump is also called peristaltic metering pump, constant flow pump, peristaltic hose pump. A peristaltic pump is a liquid transmission device that can control the flow rate. By repeatedly compressing the elastic tubing, the liquid in hose moves in a certain direction, and its flow rate is determined by the diameter of tubing and the compression speed. The liquid is delivered by alternately squeezing and releasing the elastic delivery hose of the pump. Because the longer peristaltic pump outputs a fixed amount of fluid every revolution, the precision peristaltic pump is also a kind of precision liquid dispenser, which can achieve precise metering and dosing transmission by adjusting the speed and timing.

ATO peristaltic pumps are widely used in various industries, especially medical, chemical, laboratory, aquarium and so on. Peristaltic transfer pump solves the high volume and precise dosing conveying requirements required by most applications, and improves the degree of industrial automation and intelligence.

Peristaltic pump price is reasonable, which are produced by professional manufacturer. ATO provide peristaltic dosing pumps with miniature sizes, industrial peristaltic pumps with high flow and small size, mini peristaltic pumps are available for your needs.

How to Maintain Peristaltic Pump?

Peristaltic pump maintenance requirements are low when compared to others. However, this doesn't mean that you should neglect maintenance altogether. There are some tips to help you to maintain a peristaltic pump.

• To Guarantee Rotor Function. The pump rotor can oftentimes become dismantled when removing the hose. This is caused by a pull on the tension spring. A chemical attack on the rotor can also occur if the hose is ruptured. Proper maintenance ensures the 12V peristaltic pump retains its rotary motion and prevents the need for major repairs.
• To Guarantee Proper Lubrication. Peristaltic pumps use glycerin to lubricate the hose and, sometimes, dissipate heat. Filling the housing of the pump with glycerin guarantees pump efficiency. If the glycerin is present in any other part of the industrial peristaltic pump, this is a sign of a hose leak. This is a relatively easy process that takes no longer than an hour when carried out by an unskilled individual. It is recommended to check the level of the glycerin every week.
• To Protect Peristaltic Pump Tubing. Precision peristaltic pumps have an advantage in that passing fluids don't come into contact with the pump. This means there's no need to regularly clean diaphragms, valves, or seals. Instead, you must focus your efforts on cleaning or replacing the tubing. Tubed replacements are easy to carry out given that you only need to remove the old pump tube and install a new one.

Peristaltic Pump Working Principle:

A peristaltic pump works by either two shoes or rollers rotating on a wheel inside of the pump and compressing an internal hose, which then forces through a known quantity of fluid, hence the name of the product. The hose inside of a industrial peristaltic pump is designed to return to its original shape after the shoes or rollers have passed over, so the quantity and flow of fluid are consistently maintained.

Rollers or shoes in a 24V peristaltic pump compress the tube or hose as they rotate, creating a vacuum which draws fluid through the tube. Nothing but the pump tube or hose touches the fluid, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. The animation shows fluid being drawn into a pump tube, trapped by the micro peristaltic pump head roller, and expelled when the next roller passes over the tube. As the rollers rotate, a vacuum is formed in the tube, pulling in more fluid, for the next roller pass. The complete closure of the tube when is it occluded (squeezed) between the roller and the track, gives the pump its positive displacement action, preventing back flow and eliminating the need for check-valves when the precision peristaltic pump is not running.
