Cognito’s EODD Pump Delivers Over 70% Energy Savings in Lubricating Oil Transfer for a Chinese Chemical Manufacturer

Cognito worked with one of the world’s largest energy and chemical producers, a Chinese chemical manufacturer known for setting benchmarks in operational excellence and innovation across the world. Specializing in lubricating oil transfer, the customer sought to overcome persistent challenges in its pumping operations. 

This success story highlights how Cognito’s advanced electrically operated double diaphragm (EODD) pump technology improved performance, safety, and overall cost efficiency.

Lubricating oil, with a viscosity ranging between 200–1500 cP, presents unique challenges in transfer applications. While the fluid is non-abrasive, viscosity variations require pumps that can maintain stable flow and pressure without frequent failures. Smooth, reliable lubricating oil transfer is essential to prevent process interruptions and support continuous production.

Operational Challenges

The customer’s operations relied on air-operated double diaphragm (AODD) pumps, which led to several ongoing issues: 

• Excessive energy consumption
• High noise levels during operation 
• Inadequate safety features 
• Frequent diaphragm and ball failures resulting in unplanned downtime and increased maintenance costs

To address these challenges, the customer required:

• A pump with minimal maintenance requirements
• Reduced energy consumption
• Enhanced safety features
• Faster return on investment (ROI)
• Lower noise levels for improved workplace conditions

The Right Solution: Cognito's EODD Pump

Cognito’s EODD pump solution delivered a measurable and transformative impact:

• Energy savings of more than 70% compared to AODD pumps
• Significantly lower noise levels, improving operator comfort
• Enhanced safety features for secure operation
• Robust diaphragm design supporting long-term, stable performance 
• Reduced downtime due to fewer spare part replacements and maintenance interventions

Customer Experience & Results

Replacing the existing AODD pumps with Cognito’s EODD pumps proved to be a game-changer. The customer experienced:

• A substantial reduction in operating energy costs
• Lower maintenance expenses, with diaphragm failures effectively eliminated
• Quieter operation, improving overall working conditions
• Improved reliability, ensuring uninterrupted lubricating oil transfer 

The implementation of Cognito’s EODD pump significantly improved lubricating oil transfer performance for this chemical manufacturer. By addressing energy inefficiency, noise, and maintenance challenges, Cognito delivered a solution that exceeded operational expectations. The customer expressed complete satisfaction, citing energy savings, reduced spare part consumption, and minimized downtime as key benefits.
