Product Overview

The Reciprocating Liquid Hydrogen Pump is specifically designed for high-pressure, high-flow liquid hydrogen transfer, suitable for storage, transportation, and industrial applications.

Engineered to operate reliably under extreme low temperatures and high-pressure conditions, the pump ensures safe and continuous flow of liquid hydrogen. Its robust construction supports long-term continuous operation, providing efficient pumping solutions for hydrogen fuel supply, cryogenic research, and other industrial applications.

Working Principle

The pump operates via a piston reciprocating motion within the pump chamber. Liquid hydrogen is drawn into the pump body, compressed, and delivered through the outlet piping, achieving high-pressure, high-flow transfer.

The pump body and sealing components are made of ultra-low-temperature-resistant materials, ensuring tight sealing and operational safety at liquid hydrogen temperatures. Optimized flow channels and compression structure reduce energy loss and maintain high efficiency. The system also includes safety valves and control mechanisms to prevent overpressure and operational risks.
