    Non-Metallic EODD Pump FAQs


    What conditions make Cognito Non-Metallic EODD Pumps the best option?

    Cognito Non-Metallic electric operated double diaphragm (EODD) pumps are designed for applications where chemical compatibility, corrosion resistance, and reliable solids handling are critical. These pumps perform especially well in environments where metallic pump materials may degrade or fail.

    Their durable non-metallic construction makes them ideal for transferring aggressive fluids while maintaining reliable performance and long service life.

    Common conditions where non-metallic pumps are preferred include:

    • Handling aggressive chemicals or corrosive fluids
    • Wastewater treatment and effluent transfer
    • Abrasive slurry transfer in mining or industrial processes
    • Chemical dosing and transfer systems
    • Environments requiring corrosion-resistant pump materials

    Because they combine chemical compatibility with the efficiency of electric diaphragm technology, Cognito Non-Metallic pumps provide dependable fluid transfer in challenging environments.


    What safety features do Cognito Non-Metallic Pumps include?

    Cognito Non-Metallic EODD pumps are engineered with safety and process protection in mind, helping facilities reduce risks when transferring aggressive or hazardous fluids.

    Each pump includes features designed to protect both equipment and the surrounding process.

    Key safety features include:

    • Integrated leak detection probes that monitor diaphragm integrity
    • Automatic alerts that allow pumps to shut down if a diaphragm failure occurs
    • Sealless pump design that eliminates mechanical seal leaks
    • Corrosion-resistant non-metallic materials for improved chemical compatibility
    • Reliable containment for hazardous fluid transfer applications

    These safety-focused features help facilities protect operators, equipment, and the environment while maintaining dependable fluid transfer operations.

    For additional guidance when selecting materials, use the Chemical Compatibility Tool to determine the best pump configuration for your application.


    What sizes of Non-Metallic EODD Pumps are available?

    Cognito currently offers four sizes of Non-Metallic EODD pumps, designed to support a wide range of industrial flow requirements and applications.

    Available pump sizes include:

    Each pump size is engineered to deliver the reliability of traditional diaphragm pumps with the added efficiency of electric operation. Features such as oversized diaphragms and robust internal components help extend mean time between failure (MTBF) and reduce maintenance requirements.

    Detailed specifications, performance curves, and material options are available in the individual pump data sheets.


    Are Non-Metallic EODD Pumps quieter than comparable AODD units?

    Yes. Cognito EODD pumps operate at less than 80 dB across the entire flow range, compared to AODD pumps, which can exceed 100 dB, well above the 85 dB threshold where hearing protection is typically required.


    Protect Your Pump, Process, and People

    Use our Chemical Compatibility Tool to help prevent hazardous chemical interactions that can cause equipment failure, leaks, and unsafe operating conditions.

    Hazardous Chemical IconFeatures & Benefits of the Cognito Non-Metallic Pumps

    • Oversized Diaphragms and Reduced Stroke Length: Enhance diaphragm life.
    • Dual Shaft Seals: Protect the pumping mechanism from harsh process fluids.
    • Leak Detection Probes: Standard to protect both the pump and the process fluid.
    • Horizontal or Vertical Motor Configurations: Reduce the pump's overall envelope size.
    • Available Pulsation Dampeners: Can be incorporated to reduce pulsation, protecting down steam equipment.

    Starting the pump when it trips at the end of the batch after the pressure spike shooting above the design limit was a major challenge for us. The Cognito Pump helped us eliminate this and many other issues from our production process, and proved to be a boon for our organization. The pump has had a huge impact on our processes.

    - International Sanitaryware Company

    "The absence of a reliable indication or alarm of suction choking was a big pain for us as it led to pumps running in dry condition and rupturing the diaphragm. Cognito EODD pumps solved the problems for us and help us achieve better productivity while keeping the maintenance cost to a minimum."

    - Leading Tire Manufacturer

    "The Cognito EODD pump and the innovative engineering by their team helped us maintain line pressure at set value throughout the process.
