Cognito EODD Pump Delivers Leak-Free Wastewater Transfer in Chemical Manufacturing

In the operationally critical world of chemical manufacturing, machine reliability and safety are imperative. One of the largest chemical producers in the world, headquartered in China, faced persistent challenges in its wastewater transfer process. Frequent leaks, equipment failures, unprecedented downtime, and high maintenance costs were impacting their productivity and safety.

The leaks posed safety hazards — incidents that could threaten both personnel and the facility. Additionally, downtime caused by a pump in a large operation that runs 22 hours per day was another cause for concern. 

For Safe Application

The company was using progressive cavity (PC) pumps, which frequently suffered from:

• Leaks
• Rotor and stator failures
• High maintenance costs and extended downtimes
  

The customer needed a reliable, low-maintenance, and leak-free pump solution that could reduce operational disruptions and improve safety.

The chemical company's wastewater slurry application contained flocculent components, had a specific gravity of 1.2, and flowed at 250 LPM under a discharge pressure of 3.5 barg. With a viscosity ranging from 100 to 200 cP and ambient temperature conditions, this fluid demanded a pump that could handle moderate abrasiveness and ensure continuous, leak-free operation.

Process Details

• Fluid name: Slurry (with flocculent component)
• Flow rate: 250 LPM
• Discharge pressure: 3.5 barg
• Viscosity: 100–200 cP
• Solid particle size: Flocculent (not specified)
• Temperature: Ambient

The Right Solution:
Cognito’s EODD Pump

The Cognito team proposed its electrically operated double diaphragm (EODD) pump
mounted on a complete pump skid. The EODD pump’s seal-less design eliminated leakage risks, while its robust construction ensured low maintenance and minimal downtime. Enhanced safety features further aligned with the company’s operational standards.
