What Is a Peristaltic Pump?
A peristaltic pump is a unique type of pump that makes use of compression and relaxation to move fluids through a tube. Unlike other types of pumps that suck and push fluids through their systems, a peristaltic pump achieves this by squeezing and releasing a tube with rollers or shoes.
The term “peristalsis” refers to the movement of muscles that enables food to move through the digestive system. This concept is applied in peristaltic pumps, where the rollers or shoes mimic the wave-like muscle movements and push fluids through the tube.
How Does a Peristaltic Pump Work?
A peristaltic pump functions by compressing and relaxing a flexible tube through which the fluid moves. It accomplishes this through a series of rollers or shoes, which rotate around the tube creating a flow path. As the tube compresses against the roller or shoe, it creates a vacuum that sucks the fluid into the pump. As the roller or shoe rotates, the tube regains its shape, pushing the fluid forward.
One unique feature of the peristaltic pump is the fact that the fluid only comes into contact with the tube, creating a completely contained flow path. This design can make the peristaltic pump an ideal choice in applications that require sterile or high-purity environments.
Applications of Peristaltic Pump
