A peristaltic pump, also known as a hose or tube pump, has a wide variety of use because they offer the means for transporting delicate fluids without exposure to moving parts or mechanical pistons. Every peristaltic pump has a flexible tube or hose, offering an open flow path that provides a high resistance to cut and allows the easy flow of fluids.
Despite its capacity to pump some of the world’s most difficult fluids, the peristaltic pump itself produces a gentle pumping action, which makes it ideal for a shear-sensitive product like polymers. Peristatic pumps are available in different sizes and can be used from mining applications to labs.
The Working Principle of a Peristaltic Pump
A peristaltic pump is a positive displacement pump that is used to pump different forms of fluids. The fluid is in a flexible hose fixed to inside the pump casing. The pumping principle, known as peristalsis, is based on swapping firmness and slackening of the peristaltic pump hose, drawing content in, and pushing the fluid away from the pump. The tubing is in a circular position, and the rollers rotate over the tube, forcing fluid movement through the tube. The tubing is designed to return to its original shape after the passing over of the rollers, so the flow and quantity of the fluid are maintained.
Applications of Peristaltic Pumps
Peristaltic pumps offer complete contact isolation between the process media and pump. So, this type of pump is often the preferred solution for applications where there is a necessity to eliminate cross-contamination. This is especially crucial where the operator is working with assertive fluids or even sterile fluids where they don’t want the contents to come into contact with the outside environment.
Tubing peristaltic pump tends to be used for a broad range of industrial applications because they are suitable for pumping viscous and abrasive fluids. They are also used for pumping chlorine in swimming pool use. The most common applications in the medical field occur where they are usually used for circulating IV fluids and blood.
Advantages of Peristaltic Pump
In addition to being used for pumping a variety of fluids, peristaltic pumps also have fewer mechanical parts compared to other pump technologies, reducing the requirement for worn parts. So, when required, pump maintenance is easy and quick – services consist of a simple hose change-out, lowering the cost of ownership.
In addition, the rollers move fluid through the tube, so degassing valves is not required. The rollers squeeze the tubing peristaltic pump to prevent backflow and remove the need for mechanical seals, thus generating a seal-less system.
