DIAPHRAGM METERING PUMPS

    ProMinent-dosing-pump

    ProMinent Diaphragm Metering Pump Solutions

    Diaphragm metering pumps move a precise volume of liquid at a continuous rate, making them essential for accurate dosing. These metering pumps offer adjustable flow rates, which can be changed by adjusting the stroke length or by pulse frequency. This flexibility ensures easy, reliable operation for staff in a wide range of applications.

    Features of the metering pumps includes:

    • variable stroke rates

    • manufactured from chemical inert materials

    • manual or external electronic control - analogue and SCADA options available.

    WORKING PRINCIPLE

    Metering pumps draw a measured amount of liquid into their chamber and then inject the media into a tank or pipe containing the fluid being treated.

    Core components include:

    • Pump: available in varying materials and sizes depending on the application
    • Injector: one-way valve that overcomes line pressure and ensures dosing flow
    • Foot valve: one-way valve placed in the product drum to keep the pump primed
    • Dosing line: reinforced hose or rigid pipe (PE, PVC or stainless steel) for high-pressure
    • Control system: ensures dosing accuracy and allows operators to automate on/off cycles.

    For reference, a chemical dosing pump diagram can be used to illustrate how these components work together.

    APPLICATIONS

    Diaphragm metering pumps are widely used across industries for:

    • chemical and pH dosing
    • chlorine dosing and measurement
    • batch dosing
    • petrochemical and chemical processing
    • water treatment and balancing
    • mineral processing

    FAQs

    Can diaphragm metering pumps be used in petrochemical and industrial processes?

    Yes. Metering pumps are suitable for petrochemical, water treatment and industrial applications. ProMinent models such as the Sigma and Beta 4 dosing pumps are reliable options for handling fuels, wastewater, slurries, and other challenging fluids.

    What types of liquids can metered dose pumps handle?

    Metered dose pumps can be used to transfer a wide range of media, including groundwater, potable water, salt water, wastewater, oils, slurries and process fluids. ProMinent solenoid-driven pumps, like the Concept Plus dosing pump and Delta dosing pump, are ideal for smaller capacity applications.

    Do you supply spare parts for ProMinent dosing pumps?

    Yes. Global Pumps provides ProMinent dosing pump spare parts for models including the Sigma, Beta 4, and Concept Plus ranges, ensuring long-term performance and reliability of your metering equipment.

    PRODUCT INFORMATION

    Global Pumps offer an extensive range of ProMinent dosing pumps for precise and reliable dosing. These include both solenoid-driven metering pumps and motor-driven metering pumps, ensuring there is a solution for every application. Whether you require compact metered dose pumps for low capacities or robust units for higher volume dosing, ProMinent technology delivers accuracy and durability. To support long-term performance, Global Pumps also supplies ProMinent dosing pump spare parts, ensuring your equipment remains efficient throughout its service life.

    ProMinent Solenoid-Driven Metering Pumps

    ProMinent’s solenoid-driven metering pumps are designed for lower capacities with minimal wear, making them ideal for small to medium dosing tasks. These pumps use a magnet that moves the solenoid shaft forward and backward by switching on and off, while two non-return valves prevent blowback during operation.

    Features of the solenoid-driven metering pumps:

    • capacity range: 1 to 75 L/hr at 2 to 25 bar back pressure
    • virtually wear-free power end/drive
    • long-term stability
    • cost-effective solution for lower capacity ranges
    • low energy consumption

    Models such as the ProMinent Concept Plus dosing pump and the ProMinent Delta dosing pump represent this category, delivering efficient and dependable performance where precision at lower flow rates is required.

    ProMinent Motor-Driven Metering Pumps

    ProMinent motor-driven metering pumps are built for higher capacity applications where robust technology and high precision are critical. The rotation of an electric motor is stepped down via a worm gear and converted through a cam into linear stroke movement. This motion is transferred to the diaphragm in the dosing head to provide accurate, consistent dosing.

    Features of the motor-drive metering pump:

    • extremely broad capacity range for industrial needs
    • high dosing precision even under varying pressure conditions
    • robust, cost-effective drive system for larger capacities
    • simple integration and retrofitting into automated processes

    Among these, the ProMinent Sigma dosing pump and other motor-driven models are widely used across water treatment, mineral processing, and chemical industries.

    ProMinent Dosing Pump Spare Parts

    Global Pumps supplies a complete range of ProMinent dosing pump spare parts to ensure long-term reliability and efficiency of your equipment. By using genuine and compatible spare parts, you can extend the service life of your diaphragm metering pumps, reduce downtime, and maintain dosing accuracy across industrial, water treatment, and process applications.
