A lithium iron phosphate battery manufacturing enterprise located in Hubei Province, China, faced significant operational hurdles within its critical milling machine feeding equipment. Recognising the need for a substantial upgrade, the enterprise sought advanced pumping solutions to overcome persistent challenges. This case study details how Ovell Pump, a renowned diaphragm pump manufacturer, delivered a transformative solution, significantly enhancing the client's production capabilities.

The Challenge: Inefficiency and Imprecision in Critical Processes

Prior to engaging Ovell Pump, the manufacturing enterprise relied on conventional air-operated diaphragm pump technology for its milling machine feeding operations. While functional, these existing diaphragm pumps presented several inherent limitations that directly impacted the client's bottom line and product integrity:

• ‍Imprecise and Unstable Flow: The primary concern stemmed from the erratic and less-than-smooth flow delivered by the conventional air-operated pumps. This lack of precision was particularly detrimental in the milling process, where uniform particle size is paramount. The inconsistent flow directly resulted in non-uniform particle distribution after milling, leading to a noticeable compromise in the final product quality of their lithium iron phosphate batteries.‍
• Excessive Energy Consumption and High Operating Costs: A significant drawback of the traditional air diaphragm pump systems was their inherent energy inefficiency. Operating these pumps required a constant supply of compressed air, which is an energy-intensive process. This translated into substantial energy waste and, consequently, elevated long-term operational expenses for the enterprise, eroding profitability.‍
• High Noise Levels: The continuous operation of air-operated diaphragm pumps, coupled with their associated air compressor systems, generated considerable noise. This contributed to a loud and less conducive workshop environment, potentially impacting worker comfort and safety, and adding to overall operational distractions.‍‍
• ‍Increased Maintenance and System Complexity: The reliance on a separate air compressor system introduced additional layers of complexity and maintenance requirements. This included regular servicing of compressors, air lines, and the pumps themselves, leading to higher maintenance costs, increased downtime for repairs, and a larger physical footprint within the workshop due to the auxiliary equipment.

The collective impact of these issues underscored an urgent need for a more reliable, efficient, and precise fluid transfer solution.

Seeking a Superior Solution

Driven by a commitment to operational excellence and product quality, the Hubei-based manufacturing enterprise actively sought a partner capable of providing innovative pumping technology. Their search led them to Ovell Pump, known for its expertise in high-performance fluid management solutions. The client specifically looked for advancements that could directly address their flow precision, energy consumption, and operational efficiency challenges.

Ovell Pump's Innovative Electric Diaphragm Solution

‍

Ovell Pump responded with a comprehensive solution centered on its cutting-edge Electric Diaphragm Pump (EODD) technology. For the workshop's milling machine feeding equipment, Ovell Pump implemented more than 50 units of its electric diaphragm pumps, specifically the 3-inch PP (polypropylene) model E30PAGTG and the 2-inch PP (polypropylene) model E20PPGTG. These advanced electric diaphragm pump models were strategically chosen to directly replace the problematic conventional air operated double diaphragm pump systems.

The core of this solution lay in the inherent advantages of Ovell's EODD technology:

• ‍Unmatched Control Precision: Unlike their predecessors, Ovell's electric diaphragm pumps deliver a remarkably smoother and more precise flow. This precision is critical for the milling machine feeding application, ensuring consistent material delivery and, consequently, uniform particle size after milling. The adjustable speed feature allows for fine-tuning of flow rates, directly addressing the client's primary concern regarding product quality.‍
• Exceptional Energy Efficiency: A standout feature of the EODD is its high energy efficiency. By eliminating the need for a continuous air supply from a compressor, these diaphragm pumps drastically reduce power consumption. This directly translates into significant energy savings, contributing to lower long-term operating costs for the enterprise.‍
• Reduced Operating Noise: The electric motor operation of the EODD results in significantly lower noise levels compared to pneumatic diaphragm pump counterparts. This improvement contributes to a quieter, more comfortable, and safer workshop environment for the client's personnel.‍
• Enhanced Pumping Stability and Reliability: Ovell's electric diaphragm pumps offer continuous and stable pumping, capable of achieving pulsation-free flow. This consistent performance minimises disruptions and ensures reliable operation, crucial for uninterrupted production cycles.‍
• Simplified Maintenance and Compact Footprint: The EODD's design eliminates the need for an air compressor system, drastically reducing maintenance requirements and associated costs. This also frees up valuable floor space in the workshop, contributing to a more organised and efficient operational layout. The soft start feature further reduces wear and tear, extending pump lifespan.

In addition to the widespread deployment of electric diaphragm pumps, Ovell Pump also provided a specialised solution for a distinct application within the facility: an OVELL three-inch stainless steel air-operated diaphragm pump. This robust unit was installed in a container and utilised in conjunction with a metering pump and damper. This particular configuration likely addressed a specific fluid transfer or dosing requirement where the chemical resistance of stainless steel and the precise control offered by the metering pump and damper combination were essential, further showcasing Ovell Pump's versatile capabilities as a diaphragm pump provider.

Transformative Results

The implementation of Ovell Pump's EODD technology yielded immediate and quantifiable benefits for the lithium iron phosphate battery manufacturing enterprise:

• ‍Dramatic Energy Savings: The most impactful result was the substantial improvement in energy efficiency. The client reported energy savings of up to 80% compared to their previous air-operated systems. This significant reduction in power consumption directly translated into considerable operational cost savings, bolstering the enterprise's financial performance.‍
• Superior Product Quality: The smooth and precise flow delivered by the Ovell electric diaphragm pump models directly improved the consistency of particle size after milling. This enhanced precision was a critical factor in elevating the overall quality of the final lithium iron phosphate battery products, reinforcing the client's market position.‍
• Optimised Operational Environment: The shift to low-noise electric motors contributed to a more pleasant and productive workshop environment. Reduced noise levels improved conditions for personnel and minimised operational distractions.‍
• Streamlined Maintenance and Operations: The elimination of the air compressor system simplified maintenance protocols, reducing both the frequency and cost of servicing. The compact footprint of the EODD units also optimised workshop space, contributing to a more efficient and organised production line. The ability to integrate with PLC and frequency converters further enhanced intelligent control and automation.

Conclusion

The collaboration between the Hubei-based lithium iron phosphate battery manufacturing enterprise and Ovell Pump stands as a testament to the transformative power of advanced pumping technology. By strategically replacing outdated air operated diaphragm pump systems with high-performance electric diaphragm pump models, Ovell Pump not only solved critical operational problems related to flow precision and energy consumption but also delivered a comprehensive solution that improved product quality, reduced noise, and streamlined maintenance.
