Secondary filter of medication pump

The secondary filter of the dosing pump is a filtering device installed at the output end of the dosing pump or in the pipeline system, which is used for secondary fine filtration of the liquid medicine to ensure the purity of the liquid medicine, prevent the nozzle from blocking, and improve the spray effect and equipment service life. 

    Introduction to the secondary filter of the medication pump

    The secondary filter of the dosing pump is a filtering device installed at the output end of the dosing pump or in the pipeline system, which is used for secondary fine filtration of the liquid medicine to ensure the purity of the liquid medicine, prevent the nozzle from blocking, and improve the spray effect and equipment service life. Its core function is to intercept particles, impurities, precipitates, or crystals in medicinal solutions, suitable for filtering liquid media such as pesticides, fertilizer solutions, disinfectants, etc.

    Characteristics of secondary filter for medication pump

    1. Efficient filtration
    Adopting a multi-layer filter structure (such as metal mesh, sintered mesh, or filter element), it can filter particle impurities with a diameter of 10-200 microns, and the filtration efficiency reaches over 95%.
    The filter material is corrosion-resistant (such as 304 stainless steel, polypropylene) and suitable for chemical agents such as pesticides and fertilizers.
    2. Easy to maintain design

    The filter screen can be disassembled for cleaning or replacement, and some models are equipped with backwash function to reduce maintenance costs.

    The transparent filter cup design facilitates observation of impurity accumulation and timely cleaning.

    3. Strong compatibility

    There are various interface specifications (such as 1/2 inch, 3/4 inch internal thread or quick connect interface), suitable for different models of dispensing pumps and nozzles.

    Can be used in series to form a multi-stage filtration system.

    4. Durability

    The shell material is high-strength engineering plastic (such as PA66) or stainless steel, which is impact resistant and high-pressure resistant (up to 10-20 bar).

    Suitable for harsh environments such as high temperature, high humidity, or corrosive media.

    5. Safety design

    Some models are equipped with automatic drain valves or pressure gauges to monitor the filtration status in real-time.

    Explosion proof design is optional and suitable for flammable and explosive environments.

    Scope of use of secondary filter for medication pump

    1. In the field of agriculture

    Pesticide spraying: Filter insoluble substances in pesticides to prevent nozzle clogging and ensure even spraying of the pesticide solution.

    Foliar fertilizer application: Remove impurities from fertilizers, avoid nozzle clogging, and improve absorption efficiency.

    Greenhouse irrigation: Filter particles in water to protect drip irrigation systems.

    2. Landscape and Forestry

    Urban greening: Filter impurities and protect equipment when spraying herbicides and insecticides.

    Forest protection: filter impurities in fire foam liquid to ensure spraying effect.

    3. Public health and disinfection

    Disinfection of public places: Filter sediment in disinfectant to prevent nozzle clogging.

    Animal husbandry: filter veterinary drug solution and protect spray equipment.

    4. Industrial applications

    Surface treatment: Filter particles from electroplating solution and cleaning agents to protect spraying equipment.

    Cooling system: Filter impurities in the coolant to prevent pipeline blockage.
