High-Pressure Cryogenic Piston Pump

When your application demands ultra-high discharge pressures and precise flow control for liquefied gases, a standard centrifugal pump is not enough. Our Cryogenic Piston Pump (also known as a reciprocating plunger pump) is specifically designed to handle the challenges of compressing cryogenic liquids such as Liquid Nitrogen (LIN), Liquid Oxygen (LOX), Liquid Argon (LAr), and Liquefied Natural Gas (LNG) to pressures exceeding 3,000 PSI.

Engineered for continuous industrial duty, this positive displacement pump ensures consistent performance for high-pressure cylinder filling, mist suppression, and direct injection into vaporizers.

Primary Applications

1. High-Pressure Gas Cylinder Filling:

Used extensively in gas packaging plants to fill cascades and transport trailers with high-pressure LIN, LAr, and CO2.

2. CO2 Injection Systems:

Ideal for food and beverage carbonation or enhanced oil recovery (EOR) where precise high-pressure liquid injection is required.

3. LNG Vehicle Fueling:

Provides the high pressure required for fast-filling heavy-duty vehicle fuel tanks.

4. Cryogenic Testing Labs:

Used in material testing facilities requiring precise flow of cryogenic liquids at controlled pressures.
