Product Overview

MINGXIN’s LNG Pump Skid is a modular, high-performance, and fully integrated system engineered for the highly efficient and safe transfer of Liquefied Natural Gas (LNG). By combining advanced cryogenic submerged pumps, precision control systems, and rigorous safety mechanisms into a single compact footprint, this skid ensures reliable liquid handling. It is the core prime mover for modern LNG infrastructure, catering to everything from L-CNG refueling stations to large-scale industrial storage and peak-shaving facilities.

Key Features & Design Highlights

  • Immersed Pump Technology: Utilizes premium cryogenic submerged pumps (available in single or double pump configurations) operating within a vacuum-insulated pump pool. This low-vaporization design drastically minimizes energy loss and prevents cavitation during high-speed fluid transfer.

  • Plug-and-Play System Integration: Delivered as a fully assembled, turnkey solution. The skid integrates the pump pool, pneumatic stop valves, BOG (Boil-Off Gas) vaporizer, and highly insulated cryogenic pipelines, requiring only simple fluid and electrical connections on-site.

  • 24-Hour Standby Readiness: Engineered for rapid response, featuring a quick pre-cooling process (under 2 hours) for immediate startup. The intelligent automated standby mode maintains system efficiency and cryogenic temperatures during idle periods.

  • Uncompromising Safety Compliance: Designed for hazardous environments, the skid is equipped with explosion-proof motors, emergency shutdown (ESD) systems, pressure relief valves, and real-time temperature sensors to guarantee 100% operational safety.

Technical Specifications

  • Flow Rate: 12 – 25 m³/h (per single pump configuration)

  • Pump Head (Lift): 140 – 240 meters

  • Design Pressure: 1.6 MPa – 2.5 MPa (Highly customizable to station requirements)

  • Design Temperature: -196°C

  • Motor Power: 15 kW – 30 kW (Dependent on required pump head)

  • Material: Premium 304 Stainless Steel for all cryogenic wetted parts and pipelines

  • Skid Dimensions: Highly customizable (e.g., standard footprint of 2.5m × 1.8m × 2.0m)

Industry Applications

  • LNG & L-CNG Refueling Stations: Provides high-pressure, rapid, and direct filling of LNG vehicle tanks, as well as supplying the high-pressure liquid required for CNG conversion and dispensing.

  • Industrial Gas Storage: Facilitates the high-volume transfer of LNG between massive cryogenic storage tanks and process pipelines at chemical plants and manufacturing hubs.

  • Peak-Shaving Facilities: Ensures continuous, efficient LNG distribution into city gas networks during high-demand winter periods.
