Domestic high-end equipment achieves another milestone
Leading the new era of fluid transportation worldwide

On April 15, 2025, at 2 p.m., DEPAMU Company witnessed a milestone moment - the launch ceremony of the super-large high-pressure process diaphragm pump was grandly held at the company. The birth of this groundbreaking product not only showcases the technical strength of DEPAMU Company, but also marks a new significant progress in China's high-end equipment manufacturing field, filling the domestic production gap and achieving international leading technical performance; industry experts gathered together to witness this glorious moment. Authorities from the national petrochemical, engineering design and equipment manufacturing fields, as well as authoritative experts, industry leaders and enterprise representatives from all over the country, gathered together to jointly witness this historic moment.

Leadership Address

The chairman of DEPAMU Company said in his opening speech: "The successful development of the super-large high-pressure diaphragm pump is a reflection of DEPAMU's deep commitment to core technologies. It is also an important step for China's high-end equipment to go global. In the future, we will continue to break through the 'key technology bottlenecks' and safeguard the industrialization of major countries."

Opening Ceremony

Under the joint presence of the expert team and the enterprise executives, the super-large high-pressure diaphragm pump covered with red silk cloth was officially unveiled. Its precise design structure and intelligent control system attracted widespread attention from the audience, demonstrating DEPAMU's profound accumulation in the field of fluid equipment.

On-site witnessing of performance tests

The expert team closely observed the operation test of the equipment, where the flow rate was 23.2 m³/h and the pressure was 27 MPa. The test results showed that the product exceeded the key indicators such as efficiency and stability of international similar products, earning unanimous praise from the experts.

Presentation of research results and expert discussion

The DEPAMU technical team has thoroughly analyzed the innovative breakthroughs of this product, namely the ultra-high pressure sealing technology, which enables zero leakage operation. The safety level is industry-leading. The intelligent PLC and DCS monitoring system provides real-time fault warnings, increasing maintenance efficiency by 40%. The modular design is suitable for various complex working conditions.

Expert Group Inspection and Industry Outlook

During the expert questioning and defense session, the DEPAMU technical team responded one by one with detailed data and examples, creating a lively academic atmosphere on the spot. After discussion, the expert group jointly signed the "Factory Acceptance Report for Ultra-Large High-Pressure Diaphragm Pumps", affirming that this product is "technologically advanced, with outstanding performance, and has the conditions for large-scale industrialization. It emphasizes the need to promote it vigorously in strategic fields such as refining and chemical production, coal chemical industry, and deep-sea energy."

Expert Opinion: A Milestone of "Made in China"

A national treasure, breaking through the global high-end market and being the "heart equipment" of the industrial super-large high-pressure process diaphragm pump sector, has long been monopolized by European and American enterprises. After five years of research and development, DEPAMU Company, in collaboration with top domestic research institutions, successfully broke through the technical barriers and significantly reduced China's reliance on imported equipment in the energy and chemical industries. International experts commented: "DEPAMU's breakthrough is not only a success of a single product, but also marks a leap from 'following' to 'leading' in China's equipment manufacturing industry." Expert Wei Xin pointed out: "The combination of intelligence and high reliability provides key technical support for the green transformation of the industry."

Future Journey: Building Global Standards with Innovation

At the end of the event, the chairman of DEPAMU announced in a resounding voice to the industry: The launch of this product is not the end, but a new starting point for climbing to the top of the global pump industry. We will create industry benchmarks through innovation-driven efforts and forge major national equipment through self-reliance in technology. Looking to the future, he firmly stated that the company will focus on three strategic directions: First, concentrate its resources to tackle the research and development of the next-generation ultra-large diaphragm pumps and break through the "critical technology bottleneck"; second, ensure the timely launch of four "national heavy equipment" products within this year, laying a solid foundation for high-end equipment manufacturing; third, build an integrated innovation system that deeply integrates industry, academia, and research to continuously inject powerful momentum into the construction of a manufacturing power. His powerful declaration not only demonstrates the ambition of Chinese manufacturing enterprises to scale new heights in technology, but also sketches out the blueprint for the leap from "Made in China" to "Created in China" in the process of striving forward.
