Description
Peristaltic Pumps- Principle of Operation.
Peristaltic pumps (also known as hose pumps, tube pumps) are a type of positive displacement pump which are widely used in laboratories, water treatment, chemical processing and food processing industries. It creates a steady flow for dosing and blending and is able to pump a variety of fluids with different viscosities. The laboratory peristaltic metering pumps are capable of forward and reverse pump action.
Pumping action is achieved by compression of a circular loop of elastomeric hose with two diametrically opposed rotating shoes. This rotational motion forces the fluid in the hose to move ahead of each shoe. When each shoe reaches the end of the loop, the reinforced tube immediately returns to its original shape. This ensures reliable suction and priming. The pump housing is partially filled with lubricant, aiding smooth running of the shoes on the hose. The inside of the hose and hose inserts are the only pieces of equipment in contact with pumped fluids. This facilitates the use of corrosive and even heated liquids without any damage to pumps parts.
