FS300 (0.33-0.76LPM) Brush Motor EPDM PTFE Diaphragm 300ml/min Gas-liquid Mixture Pump

FS300 series is a gas-liquid mixing pump. Currently, there are two types: FS300 and FS310. The head of FS310 is higher than that of FS300, which can reach 3bar, but it is recommended to be used below 2bar. In the future, diaphragm gas-liquid mixing pumps with higher heads (pressures) will be developed. Currently, FS300 and FS310 series have single-head and T-type double-head, and both brushed and brushless motors. The maximum liquid flow can reach 700ml/min, and the maximum gas flow is about 4LPM. It is widely used in laboratories, medical, environmental protection industries, etc.

    Features & Advantage

    Diaphragm Gas-Liquid Mixing Pump is a pump type that can simultaneously transport gas and liquid and achieve a two-phase mixing effect. It is widely used in laboratories, environments, medical and industrial equipment.

    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.
