Vertical Labyrinth Seal Cryogenic Centrifugal Pump

Key Specifications

Flow Rate: 180 m³/h

Head: 85 m

Configuration: Vertical single-stage centrifugal pump

Seal Type: Non-contacting labyrinth seal (wear-free, long service life)

Media Compatibility: LN₂, LNG, LN₂O, and other cryogenic fluids

Installation: Vertical orientation for maximum space efficiency

Core Advantages

1. Compact Vertical Layout

Vertical design drastically reduces horizontal footprint, perfect for tank farms and filling stations with limited space

Low vibration and stable operation due to vertical center of gravity

Modular vertical structure simplifies on-site maintenance and component replacement

2. Zero-Leak Labyrinth Seal for Cryogenic Service

Non-contacting labyrinth seal eliminates wear and fluid leakage, critical for volatile cryogenic media

Resists dry ice buildup and freezing, enabling faster pre-cooling cycles

Extends maintenance intervals by over 30% compared to conventional seals

3. High Head & Large Flow for Demanding Cryogenic Processes

Balanced performance of 85 m head and 180 m³/h flow meets high-pressure filling and large-scale transfer needs

Optimized hydraulic design maintains high efficiency at cryogenic temperatures, reducing energy consumption by 10%

Versatile for cylinder filling, tank unloading, and circulation systems

4. Integrated Instrumentation for Safe Operation

Built-in pressure and temperature gauges for real-time process monitoring

Supports auto-alarm and shutoff on overpressure/overtemperature to prevent dry run and equipment damage

Modular instrumentation for easy future upgrades

Typical Applications

Cryogenic tank unloading and circulation

Industrial gas (LN₂, LN₂O, LNG) cylinder filling

Chemical and energy cryogenic fluid transfer

Space-constrained small-scale process plants
