Cryogenic pumps are specialized pumping systems designed to transfer and pressurize liquefied gases at extremely low temperatures. Cryogenic pumps are used in industrial gas plants, LNG facilities, storage systems, filling stations, and other applications requiring reliable low-temperature liquid transfer.
Choosing the right cryogenic pump manufacturer or supplier involves more than comparing pump capacity. The cryogenic fluid, operating temperature, flow rate, discharge pressure, NPSH requirements, pump configuration, materials, sealing technology, testing capability, certifications, and after-sales support can all affect the final selection.
This guide reviews 15 cryogenic pump manufacturers and suppliers to consider in 2026. The companies cover specialized cryogenic pump manufacturers, major industrial pump companies, and cryogenic equipment suppliers serving LNG, industrial gases, hydrogen, aerospace, and other low-temperature applications.
The list is not an official global ranking. Companies are discussed based on their cryogenic pump portfolios, engineering capabilities, application experience, product specialization, and presence in the international cryogenic equipment market.
What Is a Cryogenic Pump?
A cryogenic pump is a pump engineered to transfer or pressurize liquids maintained at very low temperatures. Common cryogenic fluids include liquid nitrogen (LN2), liquid oxygen (LOX), liquid argon (LAr), liquefied natural gas (LNG), liquid hydrogen (LH2), liquid helium, and liquid carbon dioxide (LCO2).
Unlike conventional industrial pumps, cryogenic pumps must account for thermal contraction, low-temperature material properties, heat ingress, vaporization, changing mechanical clearances, and demanding sealing or hermetic-design requirements.
Depending on the application, cryogenic pumps may use centrifugal, reciprocating, positive-displacement, submerged-motor, vertical, or other specialized configurations.
Cryogenic Pump vs. Cryopump
Cryogenic pump and cryopump are not necessarily the same type of equipment.
A cryogenic pump is generally designed to move and pressurize a cryogenic liquid, such as LNG, LN2, LOX, LAr, or LH2. A cryopump, by contrast, is typically a vacuum pump that uses very low temperatures to capture or condense gas molecules and create a high-vacuum environment.
This distinction is important when researching cryogenic pump manufacturers because the two terms can refer to substantially different technologies, applications, and suppliers.
A complete cryogenic installation may include cryogenic storage tanks, cryogenic pumps, vaporizers, valves, pipelines, and instrumentation.
Types of Cryogenic Pumps
1. Cryogenic Centrifugal Pump
A cryogenic centrifugal pump uses a rotating impeller to transfer and pressurize cryogenic liquid. Centrifugal pumps are widely used where relatively high flow rates are required, including LNG transfer, storage facilities, industrial gas plants, terminals, and process systems.
Depending on the design, centrifugal cryogenic pumps may be installed vertically, horizontally, or as part of specialized submerged configurations.
2. Cryogenic Reciprocating Pump
A cryogenic reciprocating pump uses pistons or plungers to move liquid. These pumps are suitable for applications requiring high discharge pressure, controlled flow, or pressure boosting.
They can be particularly useful in high-pressure industrial gas, LNG fueling, hydrogen, and specialized process applications.
3. Cryogenic Submerged Motor Pump
A cryogenic submerged motor pump places the pump and motor assembly inside the cryogenic liquid. Because the motor and pump are integrated into a submerged unit, this configuration can reduce conventional shaft-sealing requirements and help minimize leakage paths.
Submerged motor pumps are widely associated with LNG and LPG transfer applications. Nikkiso, for example, describes submerged motor cryogenic pumps for LNG and LPG and operates testing equipment capable of testing pumps with LNG at approximately -162°C.
4. Cryogenic Vertical Pump
Vertical cryogenic pumps are commonly used for storage tanks, LNG facilities, industrial gas systems, and other installations where pump geometry and tank integration are important design considerations.
The specific configuration depends on tank dimensions, liquid level, suction conditions, required flow, discharge pressure, and available installation space.
5. High-Pressure Cryogenic Pump
High-pressure cryogenic pumps are designed for applications where cryogenic liquid must be delivered at elevated pressure. Typical applications include LNG fueling, hydrogen systems, high-pressure gasification, industrial gas delivery, and specialized process equipment.
High-pressure capability is a performance requirement rather than a single pump operating principle, so both centrifugal and positive-displacement technologies may be used depending on the application.

How to Choose a Cryogenic Pump Manufacturer
Not every cryogenic pump manufacturer is suitable for every application. A pump designed for LNG transfer may have very different requirements from a pump designed for liquid hydrogen, liquid helium, liquid oxygen, or high-purity nitrogen.
1. Identify the Cryogenic Fluid
Start by identifying the exact fluid. LNG, LN2, LOX, LAr, LH2, helium, and LCO2 have different boiling points, densities, vapor pressures, material compatibility requirements, and safety considerations.
The fluid should therefore be one of the first parameters provided to the pump manufacturer.
2. Define Flow Rate and Discharge Pressure
Flow rate and differential pressure are fundamental pump-selection parameters. High-flow LNG transfer may favor a centrifugal pump, while high-pressure applications may require a reciprocating or other positive-displacement design.
Specify both normal operating conditions and expected minimum and maximum operating conditions where applicable.
3. Select the Pump Configuration
Determine whether the application requires a vertical pump, submerged motor pump, centrifugal pump, reciprocating pump, high-pressure pump, or a custom configuration.
Installation arrangement, tank geometry, available space, suction conditions, maintenance requirements, and operating environment should all be considered.
4. Evaluate NPSH and Cavitation Performance
Cryogenic liquids can vaporize when local pressure approaches their vapor pressure. Proper evaluation of NPSH, suction pressure, pressure losses, liquid level, and pump inlet design is therefore critical.
Insufficient suction conditions can contribute to cavitation, unstable operation, reduced capacity, and premature component wear.
5. Check Materials and Thermal Design
At cryogenic temperatures, materials contract and mechanical clearances change. The manufacturer should demonstrate that the pump materials, shaft, bearings, impeller, seals, and other components are suitable for the specified operating temperature and fluid.
Material selection should also consider compatibility with oxygen, hydrogen, LNG, or other fluids where applicable.
6. Ask About Cryogenic Testing
Testing under cryogenic operating conditions can provide important evidence of pump performance and reliability.
Depending on the application, buyers may ask about performance testing, leak testing, vibration testing, temperature testing, system testing, and testing with the actual cryogenic fluid or a suitable representative medium.
For example, Nikkiso states that its submerged cryogenic pump testing equipment can operate with LNG at approximately -162°C.
7. Evaluate Sealing and Leakage Control
Sealing is a critical consideration in cryogenic pump design. Conventional mechanical seals can present challenges because of low temperatures, thermal contraction, and the potential for cryogenic liquid leakage.
Depending on the application, manufacturers may use submerged motor designs, hermetic construction, canned-motor arrangements, specialized seals, or other approaches to reduce leakage and heat ingress.
8. Check Certifications and Applicable Standards
Depending on the project location and application, the pump may need to comply with specific codes, standards, pressure-equipment requirements, electrical requirements, hazardous-area requirements, or marine classifications.
Before ordering, confirm the applicable standards and documentation requirements with the manufacturer, EPC contractor, end user, and local regulatory authority.
9. Evaluate Service and Spare Parts
For LNG terminals, industrial gas plants, hydrogen facilities, and other continuous-process installations, lifecycle support can be as important as initial pump performance.
Check the supplier’s service network, spare-parts availability, maintenance capability, documentation, commissioning support, and expected response time.
Choose the Right Cryogenic Pump Solution
Whether you need a standard pump, a customized system, or complete cryogenic equipment integration, we can help you select the right solution for your application.
Where Are Cryogenic Pumps Used?
LNG Terminals and Bunkering
Cryogenic pumps are used for LNG unloading, storage transfer, boosting, loading, bunkering, and other stages of LNG handling.
These systems commonly integrate with LNG cryogenic tanks, transfer equipment, vaporizers, and associated safety systems.
Large LNG installations may require high-capacity pumps capable of operating continuously under demanding cryogenic conditions.
Industrial Gas Plants
Air separation units and industrial gas facilities use cryogenic pumps to handle liquid nitrogen, liquid oxygen, liquid argon, and other liquefied gases.
Pump selection depends on the required flow, pressure, liquid properties, storage configuration, and downstream gasification or filling process.
Hydrogen Infrastructure
Liquid hydrogen infrastructure requires specialized equipment capable of operating at extremely low temperatures.
Cryogenic pumps may be used for LH2 transfer, boosting, storage, fueling, and other hydrogen-handling applications where high performance and leakage control are critical.
Aerospace and Rocket Systems
Liquid oxygen, liquid hydrogen, liquid methane, and other cryogenic propellants require specialized pumping equipment for propulsion systems, ground support equipment, test facilities, and fuel-transfer operations.
Semiconductor and Electronics Manufacturing
Semiconductor manufacturing relies heavily on high-purity industrial gases. Cryogenic equipment can be used upstream in industrial-gas production, storage, and distribution systems that support high-purity gas supply.
Healthcare and Medical Gas Supply
Large healthcare facilities and medical gas suppliers may use cryogenic storage and transfer systems for liquid oxygen and other industrial gases.
In these applications, reliability, safety, oxygen compatibility, and uninterrupted supply are important considerations.
Cryogenic Centrifugal Pump vs. Reciprocating Pump
| Feature | Cryogenic Centrifugal Pump | Cryogenic Reciprocating Pump |
|---|---|---|
| Typical flow | Medium to very high | Low to medium |
| Pressure capability | Low to high depending on design | High |
| Flow characteristics | Continuous | Controlled / pulsating |
| Common applications | LNG transfer, terminals, storage and process systems | High-pressure delivery, fueling and process applications |
| Typical advantage | High flow and continuous operation | High pressure and controlled delivery |
The final selection should be based on the complete operating envelope rather than pump type alone. Flow rate, differential pressure, NPSH, fluid properties, temperature, installation arrangement, and required operating cycle should all be considered.
Manufacturer vs. Supplier: What’s the Difference?
The terms cryogenic pump manufacturer and cryogenic pump supplier are sometimes used interchangeably, but they can describe different business models.
| Manufacturer | Supplier / Distributor |
|---|---|
| Designs and manufactures the pump | May represent one or more manufacturers |
| Provides engineering and customization | May focus on sourcing and local delivery |
| Provides factory testing and technical documentation | May coordinate third-party testing or documentation |
| Provides factory-level technical support | Often provides local service and customer support |
| Usually manages original spare parts | May stock or source spare parts locally |
For a major LNG, industrial gas, or hydrogen project, it is important to determine whether you are buying directly from the original manufacturer or through an authorized supplier. Both models can be suitable, but the responsibilities for engineering, warranty, commissioning, service, and spare parts should be clearly defined.
What Makes a Good Cryogenic Pump Supplier?
A reliable cryogenic pump supplier should be able to provide more than a basic pump datasheet. Buyers should evaluate the supplier’s engineering experience, cryogenic testing capability, material expertise, quality-control system, documentation, certifications, and after-sales support.
For international projects, confirm whether the supplier can provide performance curves, dimensional drawings, inspection records, test reports, material documentation, spare parts, operation manuals, and technical support throughout the equipment lifecycle.
The best cryogenic pump suppliers are generally those that can match pump design to actual operating conditions rather than simply offering a standard model.
What Information Is Needed for a Cryogenic Pump Quotation?
Providing complete technical information can significantly improve the accuracy of a cryogenic pump quotation.
| Parameter | Typical Information Required |
|---|---|
| Cryogenic fluid | LNG, LN₂, LOX, LAr, LH₂, helium, LCO₂, LPG, etc. |
| Operating temperature | Normal, minimum and maximum temperature |
| Flow rate | Normal, minimum and maximum flow |
| Suction pressure | Normal and minimum suction pressure |
| Discharge pressure | Required discharge pressure or differential pressure |
| NPSH conditions | Available NPSH and suction arrangement |
| Installation | Vertical, horizontal, submerged, tank-mounted, etc. |
| Power supply | Voltage, frequency, phase and motor requirements |
| Materials | Required material specifications and compatibility requirements |
| Standards | Applicable codes, certifications and project specifications |
For complex installations, providing a process datasheet, P&ID, equipment specification, or process flow diagram can help the manufacturer determine the appropriate pump configuration.
Cryogenic Pump Solutions for Industrial Gas Applications
For industrial gas plants, LNG facilities, hydrogen systems, and other cryogenic applications, the pump should be considered as part of the complete fluid-handling system rather than as an isolated component.
A complete cryogenic installation may include cryogenic storage tanks, cryogenic pumps, vaporizers, pressure-building systems, valves, pipelines, instrumentation, and gas supply equipment.
When selecting equipment, the compatibility between the pump, storage vessel, piping system, vaporizer, pressure-control equipment, and downstream gas supply system should be evaluated together.
