Whate Are Peristaltic Pumps Used For?

The earliest original designs of peristaltic pumps date back more than half a century. Peristaltic pump is a kind of roller type positive displacement pump, because its working principle is similar to the way the digestive tract transports gas, solid and liquid three-phase medium by peristaltic pump. Generally speaking, laboratory peristaltic pumps refer to small flow (ml/min) and low outlet pressure (not more than 3kg/cm2), and are mostly used in sanitary fields and laboratory measurement. The industrial peristaltic pumps are mostly used for large-flow transportation and metering in industrial occasions.

Advantages and benefits of peristaltic pumps

The unique non-sealed structure, without any leakage and pollution, in order to eliminate the risk of the pump body contaminating the fluid or the fluid contaminating the pump body, only the tube in the entire pump device is in contact with the medium.

In general, peristaltic pumps use natural rubber hoses. The inner and outer layers are complete and smooth natural rubber, which is designed to be very resistant to abrasion.

It is suitable for medium that is not highly corrosive but highly abrasive, such as mud and inorganic substances. And generally suitable for fat, oil or grease media, and organic chemicals. The inner layer is rubber, and the outer layer is natural rubber or compound rubber. The roller technology adopted, the pressure roller does not need any lubrication.

It has strong self-priming ability and self-cleaning ability, and can suck material forward and reverse.

Simple hose assembly, simple installation and maintenance, low maintenance cost and simple operation, flow can be adjusted linearly, and has a certain metering function.

It does not produce any blockage for the fluid transportation with high viscosity and impurities, the pump has a long service life, high lift and high pressure at the pump port. The first priority for designers and users of peristaltic pumps is their ability to deliver highly abrasive media.

Peristaltic pumps are used for laboratory field: quantitative transfer of laboratory fluids. 

Peristaltic pumps have excellent repeatability in dispensing and metering small volumes of fluids. Eliminates the common blockage and siphoning of fluids without the aid of any valves. Common applications in laboratory research and development are:  Aspiration of tissue culture media, dispensing agar into petridishes, flow injection ananlysis, infusion pump for tissue, specimen decolorization.

Peristaltic pumps are used for pharmaceutical field: dispensing and transferring aseptic, no-pollution and efficient.

Peristaltic pumps use non-polluting and no-corrosion pump tubing, and a variety of drives are available. In the process of solid preparation, peristaltic pump is used to transport feed liquid for spray dryer, boiling granulator, pill dropping machine, coating machine and other equipment. Biological preparations, vaccines, etc. are dispensing by high-precision peristaltic pump. Pump nutrients, pH adjusters during medium fermentation, Solvents, acids, bases, plant extracts, ointments, manufacture of IV bag dispensing.

Peristaltic pumps are used for food and chemical fields: filling and dispensing viscous and fine particle liquid.

The peristaltic pump can easily transport viscous liquids and liquids with fine particles. The peristaltic pump does not need to be cleaned, and the replacement of the fluid only needs to replace the hose. Common uses are: dispensing of fruit juice, yogurt, flavoring, syrup on food production lines, and filling of other foods. Filling of liquid semi-solids, chocolate, brine, vinegar, syrup, vegetable oil, soybean oil, honey and other foods.

Peristaltic pumps are used for environmental field

Portability and convenience are built into every Lead Fluid environmental sampling pump. Choices of DC and AC systems facilitate simple, accurate sample collection. The suction lift and noninvasive/noncontaminating designs of our pump heads and tubing enable sample collection in accordance with EPA and other standard protocols.

Peristaltic pumps are used for other field

Peristaltic pumps can work in the occasion of continuous delivery of fluids, and at the same time can find and solve many difficult problems in fluid delivery in time. 

Peristaltic pumps are used in the printing industry to transport inks and varnishes. Automatic addition of detergents in the washing machine industry, filling beverages in the beverage machine industry, reagent addition in fuel cells and batteries, cement grinding aid, concrete admixture addition, the water treatment plant is used to add chemical reagents such as sodium hypochlorite and ferric chloride to adjust the PH value of water, solar polysilicon slices for crucible spraying of silicon nitride.
