Jiangsu Haifa Machinery Manufacturing Co., Ltd.

As global oil and gas development progressively moves into deepwater and ultra-deepwater territories, the requirements for boosting equipment stability, adaptability, and efficiency in subsea oil and gas production continue to escalate. The produced media from deepwater oil and gas wells are predominantly multiphase mixtures of oil, gas, and water. Traditional separation, compression, and staged transportation models involve complex equipment, high operation and maintenance costs, and low development efficiency. In contrast, deepwater multistage gas-liquid multiphase pumps can directly enable integrated long-distance transportation of multiphase media, them the core equipment for efficient development of deepwater marginal oilfields. Built upon a mature multistage centrifugal pump structure, this equipment employs a series-connected multistage impeller boosting design, making it perfectly suited for complex operating conditions such as high backpressure, high gas void fraction (GVF), and long-distance pipeline transportation in deepwater environments. To address industry pain points such as unstable deepwater gas-liquid two-phase flow and differentiated hydraulic parameters across stages, the equipment adopts an inter-stage hydraulic matching design with optimized impeller and diffuser structures, combined with multiphase flow CFD simulation technology to optimize the flow field. This effectively improves medium pressure and velocity distribution, significantly enhancing operational stability and boosting efficiency under high-GVF conditions. The current core focus of deepwater oil and gas equipment R&D centers on key technologies such as three-dimensional hydraulic design, inter-stage structural optimization, and stable operation under high GVF, aiming to resolve challenges faced by traditional equipment including uneven gas-liquid separation, insufficient boosting, and poor condition adaptability, in alignment with the development demands of modern deepwater boosting systems. Jiangsu Haifa Machinery Manufacturing Co., Ltd. is deeply engaged in the R&D and manufacturing of high-end petrochemical and marine engineering pumps, with core products covering the full series of equipment including API 610 standard chemical process pumps, multistage centrifugal pumps,-pressure special pumps, and deepwater gas-liquid multiphase pumps. Leveraging mature hydraulic simulation technology, precision manufacturing processes, and a specialized corrosion-resistant material system, the company provides customized pump package solutions tailored to deepwater high-pressure, multiphase media, and highly corrosive conditions, fully satisfying the requirements for continuous, stable, and safe subsea oil and gas transportation. Against the backdrop of rapid development in deepwater oilfields and intelligent subsea boosting systems, efficient and highly reliable multistage gas-liquid multiphase pumps will continue to drive the efficient development of deepwater oil and gas resources, and represent the core strategic direction of Jiangsu Haifa in the high-end special pump sector.
