Peristaltic Pump

 

A peristaltic pump, also known as a roller pump is used for pumping various liquids through flexible tubes.  The pump uses a system known as perisalsis where fluid is pumped through the tube compressed by a rotor or roller.

 

Peristaltic pumps are used to pump fluids (typlically clean and sterile, but also aggressive fluids) to prevent any contamination with exposed components of the pump.  A peristaltic pump is mostly used to pump fluids that must be protected from enviromental effects and also protect the environment from the fluid.

 

A peristaltic pump is also used to pump blood the heart and lung machines during heart bypass surgery.

 

Peristaltic pump are used in water and wastewater industries, mining, food and drink, printing and chemical industries.

 

The peristatlic idea was devised in the early 1900's, this positive displacement regulates the amount of fluid that is discharged.
