Cryogenic Pump & Compressor Suppliers & Manufacturers
Cryogenic pumps and compressors move liquefied gases and process gases through the cryogenic value chain — from air separation plant cold boxes to LNG loading arms, hydrogen fueling stations, and industrial gas customer sites. Pumps handle liquid-phase transfer with limited pressure rise; compressors handle gas-phase compression from low suction pressures up to 1,000 bar for hydrogen mobility applications.
Cryogenic pumps fall into three main architectures: centrifugal for high flow and low-to-moderate head (bulk transfer, truck loading), reciprocating for high pressure up to 700 bar (hydrogen fueling, cylinder filling), and submerged motor pumps installed inside LNG storage tanks eliminating external seals and reducing heat leak. Compressors include reciprocating designs for hydrogen and syngas, diaphragm compressors for high-purity and hazardous gases, ionic liquid compressors for hydrogen fueling, and centrifugal compressors for large industrial gas plants.
This directory lists cryogenic pump and compressor manufacturers and service providers worldwide as a combined listing. Each supplier profile covers equipment types, flow and pressure ranges, compatible fluids, seal and drive configurations, certifications (ATEX, IECEx, API 610, API 618, API 674), and service network coverage for overhauls and spares.
Procurement teams typically weigh hydraulic and thermodynamic performance across the operating envelope, materials of construction for the target cryogen or gas, NPSH requirements for pumps, motor ratings and hazardous area certification, mean time between overhaul, availability of spare rotating assemblies and seal kits, and lead times which range from 12 to 52 weeks for engineered units. Filter suppliers by country, equipment type, application, or cryogen.
Frequently asked questions
What is the difference between a cryogenic pump and a cryogenic compressor?
A pump moves liquid — the fluid stays in the liquid phase throughout the machine. A compressor moves gas and raises its pressure by reducing its volume. Cryogenic systems use pumps to move liquid to end-use points and compressors either upstream in liquefaction plants or downstream on the gas side.
Why are submerged motor pumps preferred for LNG?
Submerged motor pumps install inside the LNG storage tank, with both motor and impeller immersed in the liquid. This eliminates external shaft seals (a leak path), reduces piping heat leak, and simplifies foundations. They are the industry standard for LNG in-tank pumps at import terminals and on LNG carriers.
What compression technology dominates hydrogen fueling stations?
Reciprocating compressors, ionic liquid compressors, and diaphragm compressors are all deployed at 700-bar hydrogen fueling stations. Reciprocating designs dominate on cost and availability. Ionic liquid compressors offer higher efficiency but higher capex. Diaphragm compressors are used where lubricant contamination must be avoided.
What is API 610 and does it apply to cryogenic pumps?
API 610 is the industry standard for centrifugal pumps in petroleum, petrochemical, and natural gas industries. It applies to many cryogenic centrifugal pumps in LNG and industrial gas service. API 618 covers reciprocating compressors and API 674 covers reciprocating pumps.
What are typical lead times for cryogenic pumps and compressors?
Standard catalog cryogenic centrifugal pumps ship in 12 to 20 weeks. Engineered submerged LNG pumps require 30 to 60 weeks. Hydrogen fueling reciprocating compressors currently show 40 to 78 week lead times due to constrained supply. Always plan spare rotating assemblies at time of order.
