This case study details how a large-scale industrial ink manufacturing enterprise in Zhuhai City, China, achieved superior operational safety and long-term durability by standardising its fluid transfer processes using high-specification air operated double diaphragm pump technology from Ovell Pump.

In the industrial manufacturing sector, high-performance fluid transfer systems are critical for maintaining process integrity, high safety standards, and production consistency. For the manufacture of industrial inks, these principles are paramount due to the volatile and abrasive nature of raw materials.

Located in Zhuhai City, this major industrial ink manufacturing enterprise required a reliable, scalable solution for handling high volumes of pigments and solvents within its extensive workshop environment. Facing inherent safety challenges in volatile zones and maintenance difficulties across hundreds of units, the client was actively seeking expert solutions in fluid management. After thorough consideration of diaphragm pump manufacturers, the enterprise engaged Ovell Pump, deciding to adopt the company's stainless steel pneumatic diaphragm pump technology as its new operational standard.

Operational Challenges

The industrial ink manufacturing site presented several complex challenges that required a specialised fluid transfer system that could operate reliably across over 200 installation points. The core problems revolved around safety compliance and sustained operational consistency.

• Explosion Risk Mitigation: Ink production relies heavily on volatile organic compounds and flammable solvents. Any pumping equipment in these workshop environments must be intrinsically explosion proof to prevent the risk of ignition. The complexity and cost of externally protecting electrical pumps were prohibitive given the scale of the facility.
• Chemical and Abrasive Media Handling: The pumps needed to handle varying viscosities and the abrasive nature of pigments used in industrial inks without component degradation or frequent seal failure. The continuous contact with chemically aggressive media demanded exceptional resilience from the pump's construction materials.
• Maintenance and Scale Management: With a requirement for over 200 individual pumping units, the client needed a standardised model that offered predictable, long-lasting durability and simplified maintenance protocols. Unplanned downtime across such an extensive fleet would severely compromise large-scale production flow.

With these challenges in mind, the facility needed an industrial diaphragm pump system that could offer both inherent safety and scalable reliability under continuous, high-demand conditions.

Solution: Ovell Stainless Steel AODD Pumps

‍

Ovell Pump provided a strategic, standardised fluid management solution using high-specification, stainless steel pneumatic diaphragm pump models. This approach leveraged the intrinsic safety and robust design of the air operated double diaphragm pump (AODD) technology.

The system was built around two versatile pump models tailored for specific flow rates and line sizes: the 2-inch Model A20SASTT and the 1.5-inch Model A15SASTT.

Key performance factors in the selection included:

• Inherent Safety Design: Since AODD pumps are powered by compressed air, they contain no electrical motors or spark-generating components, ensuring intrinsically explosion-proof operation. This feature simplified regulatory compliance across the entire volatile production floor.
• Material Endurance: The stainless steel construction of both models provides superior chemical resistance against the solvents and corrosive elements found in ink production, significantly extending the service life of the pump housing and manifolds.
• High-Capacity Throughput: The 2 inch diaphragm pump (A20SASTT) was selected for bulk transfer and high-flow applications, ensuring efficient material movement and contributing to rapid production throughput.
• Simplified Fleet Servicing: The standardised deployment across over 200 units allowed the client to streamline maintenance protocols and inventory management, ensuring reliable performance across the entire production network.

The combination of inherent safety, material compatibility, and scalable design made Ovell’s stainless steel AODD pumps the most practical and dependable choice for this large-scale production site.

Results and Performance

The project successfully integrated and commissioned over 200 Ovell air operated diaphragm pump units into the client's material supply and workshop production lines. This standardisation across the extensive fleet delivered immediate, verifiable operational improvements and long-term strategic value.

Key performance outcomes observed include:

• Enhanced Safety Compliance: The consistent use of AODD technology delivered excellent explosion-proof performance across the entire facility, eliminating ignition risks associated with electrical equipment in volatile zones.
• Sustained Durability and Reliability: The stainless steel construction and robust mechanics of the Ovell pumps ensured sustained, reliable operation with minimal component degradation, even under continuous use with abrasive pigments.
• Maximized Operational Uptime: Standardisation simplified preventative maintenance schedules and spare parts inventory management. This efficiency, combined with the equipment's inherent reliability, significantly contributed to high operational uptime and predictable production flow.

The implementation of Ovell’s AODD systems provided the industrial ink manufacturer with a unified, safe, and highly durable fluid transfer network, fully supporting their large-scale production requirements in Zhuhai City.

Conclusion

This case in Zhuhai City demonstrates how Ovell Pump’s pneumatic diaphragm pump technology provides dependable solutions for the industrial materials manufacturing industry. By combining inherent non-electric safety, material endurance, and long-term durability, Ovell continues to set a high standard for fluid transfer systems in demanding industrial environments.
