Product Overview

The liquid hydrogen pump is a critical piece of equipment designed for the transfer and pressurization of ultra-low temperature liquid hydrogen. It is widely used in liquid hydrogen refueling stations and other cryogenic engineering applications.

The pump features a proven reciprocating pressurization design, enabling continuous and stable delivery of liquid hydrogen under extreme low-temperature conditions. It meets the high-pressure, high-reliability, and high-safety requirements of hydrogen fueling systems.

The pump supports multi-cylinder configurations to accommodate different flow rates, ensuring efficient operation of hydrogen refueling and storage/transport systems.

Working Principle

The liquid hydrogen pump operates on the reciprocating pressurization principle. Pistons, driven by the actuator mechanism, move cyclically within the pump cylinders to draw in, compress, and discharge liquid hydrogen.

The pump’s cold end uses a vacuum-jacketed insulation design to minimize heat leak, ensuring stable ultra-low temperature operation. The integrated lubrication and drive system maintains clean, high-pressure hydrogen delivery while extending pump life and the service life of sealing components.

Key Features

Multi-Cylinder Configuration:Cylinders can be combined in different arrangements to meet various flow requirements.
Vacuum-Jacketed Cold End:Reduces heat leakage and maintains low-temperature performance under liquid hydrogen conditions.
