Long-Cycle Cryogenic Centrifugal Pump

Product Overview

The Long-Cycle Cryogenic Centrifugal Pump is specifically designed for the transfer of cryogenic liquids such as liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX). It offers high efficiency, stable operation, and long service life, making it suitable for industrial environments that require long-term continuous operation.

The pump provides high flow rate and high head performance, ensuring stable output while meeting the demands of long-duration cryogenic liquid transfer in extremely low-temperature conditions.

Working Principle

The pump adopts a multi-stage centrifugal design, where the rotating impeller generates centrifugal force to draw cryogenic liquid from the inlet and pressurize it toward the outlet, enabling efficient liquid transfer.

The pump body is manufactured with cryogenic-resistant materials and equipped with gas labyrinth sealing technology, effectively preventing leakage and ensuring stable operation during long-term continuous use. An explosion-proof motor design further ensures safe operation in environments containing flammable or explosive media.

Key Features

• High Flow Rate and Head:Flow capacity up to 100 m³/h and head up to 450 m, suitable for a wide range of industrial applications.
• Gas Labyrinth Seal:Advanced gas labyrinth sealing technology improves sealing performance and extends pump service life.
• Long-Term Operation:Designed for over 20,000 hours of continuous operation, ensuring long-term stability and reliability.
• Explosion-Proof Motor:Suitable for environments handling flammable or explosive media, ensuring operational safety.
• Strong Cryogenic Adaptability:Designed to operate reliably in extremely low-temperature environments and handle cryogenic liquids such as LNG and LN₂.

Applications

• Cryogenic Liquid Transfer:Efficient transfer and storage of LNG, LN₂, LAr, LOX, and other cryogenic liquids.
• Chemical & Energy Industries:Used in chemical plants, liquefaction facilities, and other industrial processes requiring long-term cryogenic liquid transfer.
• Marine & Storage Systems:Applied in ships, ports, and large storage terminals for cryogenic liquid transfer.
• Research & Laboratory Applications:Provides stable long-term cryogenic liquid supply for research institutes and experimental facilities.
