Product Overview

Our centrifugal cryogenic liquid pump is a high-performance solution designed for the efficient and safe transfer of cryogenic liquids, including liquid nitrogen (LN₂), oxygen (LO₂), argon (LAr), and liquefied natural gas (LNG). It is well-suited for a wide range of applications in the industrial, energy, and medical sectors, such as tank container refilling, cryogenic tank and trailer refilling, and liquid delivery.

For LNG-specific applications, our LNG Offloading & Transfer Centrifugal Pump is specially optimized for the efficient unloading and transfer of liquefied natural gas — covering LNG tank truck offloading, satellite station refilling, LNG power generation supply, and marine LNG bunkering. It delivers stable, high-flow-rate performance under demanding continuous-operation conditions.

Key Features

1. Broad Compatibility: Capable of handling multiple cryogenic liquids, offering flexibility for various industry needs.
2. Frequency Control: Allows for adjustable speed, enabling precise control of the filling rate and head to meet different operational requirements.
3. Advanced Safety Systems:
   • Safety valve alignment ensures protection against over-pressure conditions.
   • Back gas temperature interlock prevents abnormal temperature rise, safeguarding the pump's components.
   • Outlet gas pressure interlock maintains stable pressure during operation.
4. High-Speed Operation: With a speed range of 960 – 5000 RPM, it can achieve efficient liquid transfer.
5. Compact Design: Occupies less space, making it suitable for installation in different environments.

Certifications

The pump complies with either China GB standards or CE certification, meeting international quality and safety requirements. It is also manufactured under an ISO 9001:2015-certified quality management system.
