Product Overview

The High-Pressure Cryogenic Piston Pump is a high-efficiency reciprocating pump designed for the transfer of low-temperature liquids such as liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX). It delivers high pressure and high flow, ensuring stable, safe, and efficient operation during storage, transportation, and industrial processes. Its robust design allows for long-term reliable operation, making it ideal for applications requiring precision and high reliability.

Working Principle

The pump works by reciprocating piston motion, which pressurizes the cryogenic liquid and delivers it to the system piping.

During the compression stroke, the piston continuously squeezes the liquid in the pump chamber.
Optimized flow channelsand high-performance sealing systems maintain stable flow and pressure output.
This principle ensures efficient and uniform liquid transferat cryogenic temperatures while minimizing energy loss and leakage risk.
