Product Overview

The Intermittent Low-Temperature Centrifugal Pump is designed for cryogenic liquid transfer, including liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX).

It operates in an intermittent mode, providing stable flow and pressure output even under cyclic start-stop conditions. The pump’s robust structure ensures reliable operation in complex cryogenic environments, making it suitable for applications in energy, chemical, and research industries.

Working Principle

The pump operates through a motor-driven impeller that rotates at high speed. Low-temperature liquid is accelerated from the impeller center outward by centrifugal force, and velocity energy is converted to pressure energy in the guide vanes, achieving efficient liquid transfer.

Pump components are made from materials compatible with cryogenic temperatures.
Mechanical sealsprevent leakage and maintain performance during repeated start-stop cycles.
The pump is engineered to sustain stable operation under intermittent conditions, ensuring reliable delivery of low-temperature liquids.
