Glaze Transfer Application in the Refractory Industry

In the refractory industry, glaze transfer is essential for transporting viscous, abrasive, and reactive glazes through production line for continuous transferring. The efficiency of this process is critical, as it directly affects the end product's quality and durability, with inefficiencies potentially leading to defects, delays, and higher costs.

One of the leading refractory customers encountered challenges with traditional AODD pumps in this demanding application. These challenges were successfully addressed with the introduction of Cognito’s EODD pump. Let’s delve into the specifics of how this solution made a difference.

Customer Challenges

Higher Energy Consumption:

The process demanded continuous operation for 23-24 hours daily, resulting in substantial energy costs due to the need for a constant continuous supply of pneumatic air.

Lack of Safety Features:

The absence of leak detection mechanisms in AODD pumps led to undetected leakages from diaphragm ruptures, resulting in significant safety hazards and operational disruptions.

Elevated Maintenance Costs:

Frequent diaphragm ruptures due to the abrasive nature of the operating liquid, as well as the overall requirements of the pump assembly, resulted in significant maintenance costs.

Higher Downtime and Production Loss:

Frequent downtime and repairs impacted total expenses.

Process Details

Fluid: Glaze (very abrasive in nature)
Flow Rate: 325 LPM
Discharge Pressure: 3.5 Barg
Viscosity: 2000 Cp
Specific Gravity: 1.7

The Right Solution

EODD pumps offer greater efficiency and power than traditional AODD pumps. Their electric operation and advanced safety features reduce energy use, quickly detect leaks and stop the pump, and ensure reliable performance. Additional safety features further lower maintenance costs and extend pump longevity in challenging conditions.

The Cognito team successfully convinced the customer to replace their 3” AODD pumps with 3” EODD pumps by showcasing the above benefits along with the ROI calculations. These features promised to cut maintenance needs, extend the lifespan of critical components by 2 to 3 times apart from the significant energy savings. These significant benefits made a strong case for the replacement.
