DSW supplies industrial cryogenic liquid pumps for transferring and pressurizing liquefied gases at extremely low temperatures. Our cryogenic pumping equipment is designed for applications involving liquefied natural gas (LNG), liquid oxygen (LOX), liquid nitrogen (LIN), and liquid argon (LAr). These pumps support industrial gas transfer, storage tank filling, tanker loading and unloading, and cryogenic liquid distribution.
Available pump configurations vary according to the liquid medium, required flow rate, discharge pressure, operating temperature, and installation conditions. DSW provides cryogenic pump supply solutions for industrial gas facilities, air separation plants, LNG handling operations, and other cryogenic liquid processing applications.
Types of Cryogenic Liquid Pumps
Different cryogenic pump types are designed to meet specific liquid transfer, pressure, and installation requirements. Common configurations include centrifugal, reciprocating, and submerged cryogenic pumps.
| Cryogenic Pump Type | Description and Applications |
|---|---|
| Cryogenic Centrifugal Pumps | Cryogenic centrifugal pumps use rotating impellers to transfer liquefied gases. They are suitable for continuous liquid transfer, circulation, and applications requiring relatively high flow rates. Typical uses include LNG handling, cryogenic storage tank transfer, and industrial liquid supply systems. |
| Cryogenic Reciprocating Pumps | Cryogenic reciprocating pumps use piston or plunger mechanisms to deliver cryogenic liquids at elevated pressures. They are commonly applied in high-pressure liquid transfer, cryogenic tanker filling, and liquid gas filling operations. Pump capacity and pressure should be matched to the requirements of the receiving system. |
| Submerged Cryogenic Pumps | Submerged cryogenic pumps are installed within compatible cryogenic vessels or storage tanks. Their configuration can help reduce suction-related challenges associated with handling low-temperature liquids. They are used in specialized LNG and other cryogenic liquid transfer systems, depending on the design and operating conditions. |
Applications of Cryogenic Liquid Pumps
Industrial cryogenic pumps support liquid gas transfer, storage, processing, and distribution across various industries.
- Industrial Gas Transfer: Transfer liquid oxygen, nitrogen, and argon from storage tanks to vaporizers and downstream supply systems, with flow rate and discharge pressure matched to operating requirements.
- LNG Storage and Transfer: Move liquefied natural gas between storage tanks, transport vessels, and downstream handling equipment according to the required transfer capacity and system pressure.
- Air Separation Plants: Transfer liquid oxygen, nitrogen, and argon between air separation process equipment and cryogenic storage systems.
- Cryogenic Tank Filling and Distribution: Fill and transfer liquefied gases into compatible storage vessels, cryogenic tank trailers, and other liquid distribution equipment.
Cryogenic Pump Selection Considerations
Selecting the appropriate cryogenic liquid pump requires evaluating the characteristics of the liquid and the operating requirements of the complete transfer system.
| Selection Parameter | Key Considerations |
|---|---|
| Liquid Medium | LNG, LOX, LIN, LAr, or other cryogenic liquids |
| Operating Temperature | Liquid temperature and compatible pump operating range |
| Flow Rate | Required transfer capacity and process demand |
| Discharge Pressure | Required delivery pressure and downstream system resistance |
| Pump Configuration | Centrifugal, reciprocating, submerged, or other suitable designs |
| Installation Conditions | Tank arrangement, suction conditions, and available installation space |
| Material Compatibility | Wetted materials suitable for the cryogenic liquid and service conditions |
For liquid oxygen applications, oxygen compatibility, material cleanliness, and applicable safety requirements must be carefully considered. Final pump specifications should be confirmed according to the intended application and operating conditions.
