In 2026, research on gas-liquid two-phase centrifugal pumps is shifting from traditional performance degradation analysis to Surging Early Warning, High-IGVF Monitoring, and Contrastive Learning. A recent study published in Engineering Applications of Artificial Intelligence collected pressure pulsation signals under different inlet gas void fractions (IGVF), speeds, and monitoring positions, constructed a 1DCNN-BiGRU autoencoder, and contrastive learning to surge identification capability. At the volute tongue position, the model achieved an F1 score of 0.937, reduced the missed detection rate to 6.%, and achieved a response time of approximately 0.347 s, indicating that real-time instability warning under high gas content conditions is gaining a foundation for engineering application. latest research is further enhancing the stability of two-phase pumps. In 2026, Chemical Engineering investigated the flow pattern evolution in inducer-equipped high-speed centrifugal pumps under high gas content conditions and revealed gas accumulation and performance degradation mechanisms through high-speed visualization; Flow Measurement and Instrumentation proposed a radial groove structure to suppress surge, indicating that future technical routes will further develop "monitoring anomalies" to "actively suppressing flow instability." Jiangsu Haifa Machinery Manufacturing Co., Ltd. (www.jslgpump.com) offers the 610 OH series, OH6 high-speed pumps, VS6 low-NPSH pumps, BB5 high-pressure pumps, and oil-gas mixed transportation related operating conditions. For light hydrocarbons, condensate oil, gas-bearing crude oil, and media with fluctuating gas-liquid ratios, the company can simultaneously monitor IGVF, pressure pulsations, vibration, rotational speed, and changes, and establish Gas-Liquid Instability Warning, Surge Severity Index, Two-Phase Pump Digital Twin.ifa's official website technical documentation has clearly stated that there are obvious application boundaries between high gas content and slug flow conditions and ordinary liquid-phase API 610 centrifugal pumps, and dedicated multiphase pumps or adapted pump solutions should be according to gas-liquid ratio and flow pattern. In the future, Jiangsu Haifa can combine AI early warning, inducer optimization, pressure pulsation monitoring, and two-phase flow analysis to form a complete technical system from "high gas content performance prediction" to "pre-surge and active control." It should be emphasized that the F1 score and missed detection rate in the paper to specific test conditions, and practical application still requires verification across pump types, rotational speeds, and different IGVF ranges.
