Product Overview

MINGXIN’s LNG Centrifugal Pump is a high-performance liquid transfer solution specifically engineered for the highly efficient and safe handling of Liquefied Natural Gas (LNG) and other cryogenic fluids. Tailored for the rigorous demands of the industrial, energy, and medical sectors, this pump serves as the ideal prime mover for ISO tank container unloading, cryogenic semi-trailer refilling, and bulk liquid delivery networks. Its compact footprint ensures seamless integration into environments with limited installation space.

Key Features & Safety Systems

  • Variable Frequency Control: Equipped with advanced adjustable speed capabilities (VFD), allowing operators to precisely regulate the filling rate and pump head to meet dynamic operational requirements.

  • Broad Cryogenic Compatibility: expertly designed to handle LNG and other cryogenic liquids, offering maximum flexibility for diverse industry applications.

  • High-Speed Efficiency: Operates across a wide speed range from 960 to 5,000 RPM, guaranteeing rapid, high-volume liquid transfer with minimal product loss.

  • Advanced Safety Interlocks: Engineered with a uncompromising "safety-first" design, featuring:

    • Safety Valve Alignment: Prevents internal over-pressure conditions.

    • Back-Gas Temperature Interlock: Immediately detects abnormal temperature rises to protect critical pump components from vapor lock or friction damage.

    • Outlet Gas Pressure Interlock: Ensures the discharge pressure remains stable and within safe operating limits.

Technical Specifications

  • Pump Head (Lift): 10 – 250 meters

  • Filling Rate (Flow): 5 – 24 m³/h

  • Working & Design Temperature: -196°C

  • Operating Speed: 960 – 5,000 RPM

  • Material Construction: Premium S30408 Stainless Steel for enhanced strength and durability at extreme low temperatures.
