Product Overview

MINGXIN’s Cryogenic Centrifugal Pump is a high-performance, precision-engineered solution designed for the safe, fast, and highly efficient transfer of cryogenic liquids, including Liquid Nitrogen (LN₂), Liquid Oxygen (LO₂/LOX), Liquid Argon (LAr), and Liquefied Natural Gas (LNG). Tailored to meet the rigorous demands of the industrial gas, energy, and healthcare sectors, this pump is the ideal choice for ISO tank container loading, cryogenic trailer refilling, and continuous liquid delivery networks.

Key Features & Safety Systems

  • Broad Fluid Compatibility: Expertly handles multiple cryogenic liquids, providing maximum operational flexibility for diverse industry needs.

  • Variable Frequency Control: Features adjustable speed settings (VFD) that allow operators to precisely control the filling rate and pump head, adapting seamlessly to different operational requirements.

  • Advanced Safety Interlocks: Engineered with a strict safety-first approach. It includes safety valve alignment for over-pressure protection, a back-gas temperature interlock to prevent abnormal internal heating, and an outlet gas pressure interlock to guarantee stable operation.

  • High-Speed Efficiency: Operates across a broad speed range of 960 to 5,000 RPM, ensuring rapid and highly efficient fluid transfer with minimal loss.

  • Compact & Space-Saving Design: Its optimized footprint allows for easy installation and integration into existing gas stations, skids, and environments with limited space.
