• Overview of Juneng Machinery:

Juneng Machinery, headquartered in Yixing, Jiangsu Province, China, stands as a leading integrated manufacturer of industrial separation equipment with over 35 years of industry experience. Founded in 1989 as Yixing Industrial Pump Factory, the company has evolved into a high-tech enterprise specializing in centrifuges, filters, pumps, evaporators, and pressure vessels. With four major production bases covering 500,000 square meters and fixed assets valued at 660 million yuan, Juneng operates one of the most advanced manufacturing ecosystems in China’s machinery sector. The company serves more than 25,000 global clients across pharmaceuticals, food & beverage, petrochemicals, energy conservation, and environmental protection industries. Notably, in 2024, Juneng achieved sales exceeding 800 million RMB, with 20% of its output exported to over 20 countries—highlighting its strong international footprint. Its commitment to quality is validated by ISO9001, ISO14001, ISO45001, CE, ASME, CCS, and dual-system certification (AA level). A key milestone was the launch of its pharmaceutical-grade centrifuge series in 2021, which met stringent GMP and FDA standards. This focus on innovation and compliance has earned Juneng multiple national science and technology awards, including the Second Prize of China Machinery Industry Science and Technology Award. The company’s engineering department, established in 2015, now delivers turnkey solid-liquid separation system solutions, further cementing its reputation as a full-service provider. With a workforce of 1,300 skilled professionals and a robust R&D pipeline, Juneng continues to push boundaries in separation technology while maintaining cost-efficiency and scalability—making it a preferred partner for both large-scale industrial projects and customized applications.

• Core Products and Innovations:

At the heart of Juneng Machinery’s success lies its world-class disc stack centrifuge technology, particularly exemplified by the DBY313 model—a high-performance continuous disc separator designed for demanding industrial environments. This system excels in three-phase separation, effectively isolating oil, water, and solids simultaneously, making it ideal for applications in dairy processing, edible oil refining, biofuel production, and marine bilge water treatment. One notable real-world case involved a major Chinese vegetable oil producer facing challenges with impurity retention and inconsistent product clarity. After integrating Juneng’s DBY313 centrifuge into their production line, the client reported a 40% reduction in residual solids, a 30% increase in throughput, and consistent oil purity meeting international food safety standards. The system’s fully sealed design and automatic CIP/SIP cleaning capabilities ensured zero cross-contamination, critical for GMP-compliant facilities. Another success story came from a petrochemical plant in Southeast Asia that used Juneng’s KYDB204 stainless steel continuous centrifugal separator to treat oily wastewater. Prior to installation, the plant struggled with frequent clogging and high maintenance costs. Post-installation, the system operated continuously for over 18 months without downtime, achieving a separation factor of up to 14,600 and reducing oil content in effluent to below 0.01%, well within regulatory limits. This performance was made possible by Juneng’s proprietary stress analysis using ANSYS software, precision machining of duplex stainless steel drum discs, and dynamic balance testing in an underground overspeed lab. Furthermore, Juneng’s recent launch of vertical scraper centrifuges in 2024 completed its full centrifuge portfolio, enabling seamless integration into complex process lines. With a supply capacity of 20 sets per month and delivery within just 20 days, Juneng offers rapid deployment and scalable solutions tailored to diverse industrial needs—proving that innovation, reliability, and customer-centric engineering define its leadership in the disc oil separator market.

• Key Technologies in Disc Separators:

Alfa Laval’s disc stack centrifuges are engineered around several groundbreaking technologies that redefine separation performance. Central to their design is the patented 'Hydrodynamic Flow Control' system, which optimizes liquid flow through the disc stack to enhance separation efficiency while minimizing turbulence and wear. The company’s use of advanced materials—such as titanium alloys and high-strength stainless steels—ensures exceptional resistance to corrosion and mechanical stress, even under extreme temperatures and pressures. Another hallmark feature is the 'Self-Cleaning Disc Stack,' which automatically removes accumulated solids during operation, significantly reducing manual intervention and maintenance frequency. This is especially valuable in continuous processes like milk clarification or biodiesel purification. Alfa Laval also integrates smart sensors and IoT-enabled monitoring systems into its centrifuges, allowing real-time data collection on vibration, temperature, pressure, and throughput. This enables predictive maintenance alerts and remote diagnostics, reducing unplanned outages by up to 60%. Their latest generation of centrifuges, such as the APV M Series, features variable-speed drives and AI-driven control algorithms that adapt to changing feed conditions, ensuring optimal performance regardless of load fluctuations. Additionally, Alfa Laval’s centrifuges comply with international standards including CE, FDA, and HACCP, making them suitable for sensitive applications in food, pharma, and medical industries. These innovations not only improve productivity but also contribute to lower energy consumption and reduced carbon emissions—aligning with global sustainability goals. Through decades of refinement and real-world validation, Alfa Laval continues to lead the way in developing intelligent, efficient, and environmentally responsible disc oil separator solutions.
