Digital variable speed peristaltic pumpIt is a liquid conveying equipment that achieves flow regulation through digital control, widely used in fields such as scientific research, pharmaceuticals, and chemical engineering. The core principle is to use a rotating roller to periodically squeeze the elastic hose, so that the liquid inside the hose can be transported in a directional manner under the action of peristalsis. The liquid only contacts the inner wall of the hose, avoiding cross contamination with other components of the pump body.
The digital variable speed peristaltic pump adopts a modular design, supporting multiple pump head and hose combinations, and can adapt to hoses with different inner diameters and materials to meet the transportation needs of liquids with different viscosities and corrosives. The operation interface is usually equipped with an LCD graphic display screen, supporting multiple language menus such as Chinese and English, which can intuitively set parameters such as operation mode, flow rate, and allocation volume. The device also has programming functions, which can preset modes such as timed allocation, repeated allocation, and volume allocation to achieve automated operations.
Digital variable speed peristaltic pumpIts main application scope:
1. In the field of biology and medicine
Laboratory analysis:
Used for precise delivery of reagents, buffer solutions, culture media, etc., commonly used in biochemical analysis, cell culture, PCR experiments, etc.
Advantages: Low shear force to avoid damaging biological samples (such as cells, DNA), programmable flow control.
Drug development and production:
Transporting drugs, active ingredients, or corrosive solvents (such as high concentration acids/bases) in accordance with GMP standards.
Medical equipment:
Cooperate with infusion pumps, dialysis machines, chemiluminescence analyzers and other equipment to achieve precise drug delivery or waste liquid treatment.
2. Chemical and Environmental Protection Industry
Chemical fluid transport:
Dealing with corrosive liquids (such as strong acids, strong bases, organic solvents), the peristaltic pump hose can be replaced (such as fluororubber, PTFE material) to avoid equipment corrosion.
Example: Additive delivery in acid-base neutralization and chemical synthesis reactions.
Water treatment and sewage treatment:
Accurately adding coagulants, disinfectants (such as sodium hypochlorite), and scale inhibitors for reverse osmosis systems.
Environmental monitoring:
Collection of water samples, transportation of condensed water in gas sampling, or fluid control during trace pollutant analysis.
3. Food and Beverage Industry
Accurate ingredients:
Transport viscous liquids (such as syrup and sauce) and granular materials (such as juice and dairy products) to avoid blockages in pipelines.
Advantages: The hose can be disassembled and cleaned, meeting food safety standards such as FDA and 3A certification.
Filling and packaging:
Used for low-dose filling (such as seasonings, cosmetics), or as a substitute for traditional pumps to avoid cross contamination.
4. Agriculture and Horticulture
Precision fertilization and irrigation:
Proportionally delivering water-soluble fertilizers, nutrient solutions, or pesticides, especially suitable for soilless cultivation and hydroponic systems.
Advantages: Adjustable flow rate to meet the needs of different crops; Anti clogging design is suitable for granular fertilizers.
Greenhouse environmental control:
Cooperate with the atomization system to transport water or chemicals and achieve automated management.
5. Energy and Electronics Industry
Fuel cells and new energy:
Transporting electrolyte, coolant or hydrogen fuel requires low pulse and high-precision flow control.
Semiconductor manufacturing:
Transport photoresist, etching solution or cleaning solution to avoid bubble formation and ensure process stability.
Instrument cooling:
Circulating coolant (such as ethylene glycol solution) to high-temperature devices such as laser equipment and X-ray machines.
