Peristaltic Pump

Peristaltic Pumps are the world's fastest growing pump type. A peristaltic pump is used to pump clean or sterile fluids because the pump cannot contaminate the fluid, or to pump aggressive fluids because the fluid cannot contaminate the pump. Peristaltic pumps are also referred to as flexible member pumps, flexible tube pumps, dispensing pumps, or dosing pumps or hose pumps or tube pumps.

How does a peristaltic pump works?
A peristaltic pump uses a rotating roller pressed against special flexible tubing to create a pressurized flow. The tube is compressed at a number of points in contact with the rollers or shoes. The media is moved through the tube with each rotating motion. The individual components of a peristaltic pump include a pump head, drive, and tubing. As the rotor turns, the part of tube under compression closes thus forcing the fluid to be pumped to move through the tube.

Types of Peristaltic Pump:

• Higher pressure peristaltic pump :Typically uses reinforced tube which is often called hose and the class of pump is often called a hose pump.
  
  
• Lower pressure peristaltic pump : Typically uses non-reinforced tubing, and the class of pump is sometimes called a tube pump or tubing pump.

Applications of Peristaltic Pump:
Peristaltic Pumps are are used in a variety of industries and applications. They are as follows:

• Commercial Swimming Pools
  
• Water Conditioning
  
• Agricultural and Industrial Applications
  
• Petrochemical
  
• Surface Treatment
  
• Building Construction
  
• Mining Industry
  
• Food and Beverage Processing
  
• Pulp and Paper Production.
  
• Pharmaceutical Processing
  
• Semiconductor
  
• Power Generation
  
• Medical Applications
  

Uses and Features of Peristaltic Pumps:

• Seals and valves are not needed as in other pumps. Hence, they do not need any maintenance.
  
  
• Peristaltic pumps come with wash down capabilities and/or IP54 or IP55 ratings.
  
  
• Peristaltic pumps are also reversible and are generally used to clean out the hose or tubing.
  
  
• Single head and dual head pump options are also available.
  
  
• The tubing in peristaltic pumps is often replaceable or disposable.
  
  
• When choosing between peristaltic pumps, flow rate is proportional to the rotation of the rollers.
  
  
• These pumps combine precise positive displacement and low maintenance requirements with the ability to handle abrasive and aggressive fluids, which wear out many other pump types. This unique combination of features often proves to be a cost-effective alternative used in difficult pumping applications.
