Main features of diaphragm gas-liquid mixing pump
● Compact structure, small and light
Suitable for systems with limited volume, such as portable instruments.
● Leak-free design
The diaphragm completely isolates the liquid from the drive system to avoid cross contamination, especially suitable for handling sensitive or corrosive liquids.
● Strong self-priming ability
Usually can start with dry suction, with good self-priming performance (up to 2~3 meters of liquid column).
● Can run dry for a short time
Some models allow short-term operation without liquid, which is not easy to damage.
● Low power consumption, low noise, low vibration
Suitable for equipment with strict noise requirements, such as medical and laboratory applications.
● Easy maintenance and long life
No lubricating oil is required, the diaphragm is a replaceable part, easy to maintain.
● Compatible with a variety of liquids
The pump head material is optional (such as PTFE, EPDM, PVDF, etc.), supporting the delivery of a variety of chemical liquids or weakly corrosive liquids.
Main application areas of Diaphragm Gas-Liquid Mixing Pump
1. Laboratory instruments
● Chemical reaction system: achieve precise mixing of reaction gas and liquid to improve reaction efficiency.
● Microfluidic system: perform gas-liquid mixing and transmission in the chip to facilitate small volume sample analysis.
● Sample pretreatment equipment: used to mix liquid samples with carrier gas for subsequent detection (such as chromatographic analysis).
2. Environmental protection and online monitoring
● CEMS system (continuous flue gas emission monitoring): mix condensate and gas for discharge or treatment.
● Water quality monitoring instrument: extract water samples and mix with gas to promote reaction or transmission.
3. Medical equipment
● Atomization device: mix disinfectant or liquid medicine with air to form a fine spray.
● Cell culture system: mix oxygen and culture medium in a bioreactor.
● Gas-assisted injection system: push liquid to the target site through gas pressure.
4. Consumer electronics and household appliances
● Aromatherapy machine, water oxygen machine: mix liquid with gas to produce a long-lasting atomized aroma.
● Smart toilet spray system: Mix cleaning liquid with air and then spray to improve cleaning efficiency.
5. Industrial application
● Spray cooling system: Mix water and gas to cool the surface of equipment or mold.
● Automatic lubrication system: Gas drives lubricating oil to atomize and accurately deliver it to the equipment.
● Surface treatment/coating: Mix liquid coating with gas to form a uniform spray effect.
6. Automobile field
● SCR urea injection system: Mix urea solution with gas to form a spray to assist exhaust gas treatment.
● Engine internal cleaning system: Gas pushes cleaning liquid into the pipeline or combustion chamber.
