LNG Submerged Pump
Higher Throughput · Operational Flexibility · Integrated Cryogenic Transfer
The BAIYAN Dual-Pump LNG Submerged Pump Skid is designed for LNG fueling stations that require higher transfer capacity, flexible operating modes or improved service continuity. Two cryogenic submerged pumps are integrated with the pump sump, cryogenic piping, valves, instruments and control interfaces to form a coordinated LNG transfer module.
Designed for Demanding LNG Station Operation
Each submerged pump uses a fully immersed, seal-less structure. Moving components are cooled and lubricated by the cryogenic liquid, while variable-frequency control allows pump output to be adjusted for different fueling and transfer conditions.
The dual-pump arrangement can be engineered for parallel duty, alternating operation or project-specific duty/standby logic. Final control philosophy is confirmed during engineering.
Key Features
Two-pump configuration: Supports higher-demand stations and flexible operating strategies.
Fully submerged, seal-less pump design: Helps reduce shaft-seal-related maintenance points.
Cryogenic liquid cooling and lubrication: Rotating components operate within the LNG medium.
VFD control: Pump speed can be adjusted for multiple station operating conditions.
High-head performance: Models are available for different required flow and head combinations.
Integrated skid assembly: Pumps, cryogenic piping, valves and instruments are coordinated within one module.
Factory inspection: Assembly and agreed inspection items are completed before shipment.

FAQ
Why use two LNG pumps?
A dual-pump skid can support increased capacity or a more flexible operating strategy. The selected mode depends on the required station throughput and continuity plan.
Can different pump models be selected?
Yes. Pump power, flow and head are selected according to the station process and operating conditions.
What information is needed for selection?
Please provide the required flow, discharge pressure or head, daily fueling demand, operating mode, voltage, ambient conditions and piping interface requirements.
