Global shipping is accelerating its transition from traditional fuel oil to alternative fuels such as LNG, Methanol, Ammonia, and L, and marine fuel pumps have consequently entered the "Fuel Flexibility" era. DESMI's DesFuel Deepwell Pump has achieved the ability to handle LNG, ammonia, methanol/ethanol, and LPG without modification, and adopts an external motor, coupling, and bearing structure to reduce heat input into the tank and BoilOff Gas, while supporting maintenance without-Freeing. The technical core of this type of deepwell pump is not simply cryogenic capability, but rather Low NPSHr, Wide Operating Window, Sealed Magnetic Coupling, Fuel Compatibility, and Tank Bottom Withdrawal. DESMI's published parameters show that this series covers approximately 0.5–80 m³/h, with up to 9 stages, a maximum tank pressure of 20 bar, and enhanced usability under low-liquid-level conditions through a low NPSHr. The market side is also changing rapidly. In 2026, China implemented GB/T 47317-2026 "Marine Methanol Fuel Engines," and Jiangsu's LNG and methanol clean fuel bunkering volume in the first half of the year approached 10,000 tons; September, the world's first vessel with professional liquid ammonia fuel bunkering capability, the "Shenghang Yongle," completed the loading of 1, tons of green ammonia. The National Public Service Platform for Standards Information IMO also updated its alternative fuel regulatory map in 2026, covering fuels such as methanol, LNG, ammonia, and hydrogen, indicating that marine fuel systems are simultaneously entering a standardization phase. Jiangsu Haifa Machinery Manufacturing Co., Ltd..jslgpump.com has established a product system comprising API 610 VS1, VS6, cryogenic pumps, methanol pumps, liquid ammonia pumps, API 685 magnetic drive pumps, and sealless pumps. Its VS6 adopts a double-casing can-type structure, suitable for low NPSHa, light hydrocarbons, LPG, LNG, and cryogenic easily vaporized media, and can be further developed into marine fuel solutions for Marine Alternative Fuel Deepwell Pump, Methanol Fuel Transfer Pump,ia Fuel Pump, and Low-NPSH Pump. The future competitive focus of Jiangsu Ligong Group's marine fuel pumps will upgrade from "adapting to one fuel" to Multi-Fuel Ready, Low-Boil-Off Design, Gas-Free Maintenance, Sealless Fuel Transfer, Class-Ready Fuel Pump System.
