Non-Metallic EODD Pumps

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.

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.

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

Available pump sizes include:

• 1½" Non-Metallic EODD Pump
• 2" Non-Metallic EODD Pump
• 3" Non-Metallic EODD Pump

A 1" model is currently in development and will expand the available range for smaller flow applications.

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.
