Nikkiso delivers enhanced reliability and performance with next-generation submerged motor pump
2 July 2026
Temecula, Calif. – Nikkiso Clean Energy & Industrial Gases Group (Nikkiso CE&IG) has today launched the next generation of its submerged motor pump to deliver higher performance and greater reliability for a range of markets.
The SMP 34 has been specifically designed to meet the needs of the widest application range in the market, including power generation; bunkering and import/export terminals; trailer loading and offloading; peak shaving, and fuel supply systems.
Nikkiso CE&IG has more than 11,000 of the SMP 34’s predecessors in operation already and based on that experience this next-generation submerged motor pump delivers enhanced reliability, with a mean time of 20,000 hours between overhauls. When intervention is required, the quick-locking assembly means maintenance can be completed up to 30% faster.
The flexible design of the SMP 34 also means it comes with a wider operating range – now including liquid hydrogen alongside LNG, ammonia and nitrogen – plus higher performance levels with up to 80% hydraulic efficiency.
Emile Bado, President of Nikkiso CE&IG’s Cryogenic Pumps and Expanders Business Unit, said: “We pioneered the first commercially deployed submerged liquid hydrogen pump, and that spirit of innovation continues with the launch of the SMP 34.
