Product Overview

The Large-Flow Medium-Pressure Cryogenic Piston Pump is a high-efficiency pump specifically designed for the transport of low-temperature liquids such as liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX). It provides high-flow delivery under medium pressure, ensuring stable and safe liquid transfer during storage, transportation, and distribution. With its reliable long-term operation capability, it is ideal for large-scale cryogenic liquid handling systems and industrial applications.

Working Principle

The pump operates by reciprocating piston motion, which pressurizes and discharges the cryogenic liquid into the piping system, achieving high flow rates with stable medium pressure output.

Optimized liquid flow channelsand high-performance sealing systems ensure smooth, efficient pumping at cryogenic temperatures.
The design minimizes energy loss and leakage risk, maintaining safe and stable operation even under demanding conditions.
