Cryogenic liquid pump
Thread Content
Currently, the manufacturers of cryogenic liquid pumps include CRYOSTAR, FIVES, and CRYOMEC AG. Who else are there, and which companies offer products with better quality and greater reliability in operation? Please give me some advice.
The cryopump manufacturers I’ve dealt with include NIKKISO and Shinko from Japan； United States: EIC (ebara international corporation), JC-Carter. Hope this is useful to you
External types include CRYO-STAR, ACD, CRYO-MEC, CRYO-MACH, etc. Submersible pumps that are widely used in the air separation and LNG industries include NIKKISO, EBARA, Carter, ACD, CRYO-STAR, etc
May I ask what the Chinese names of these manufacturers are?
Colesda (its domestic factory is in Hangzhou); ACD (its domestic subsidiary is Hangzhou Brown). It seems that these two companies do not have domestic facilities, and they are both engaged in import-export and agency trading
I’d like to know; if any of you know, could you please answer?

Applicable media: nitrogen, methane (LNG), argon, ethylene • Flow rate: 5-140 gpm • Required net positive suction head: 0.9-4.5 m • Head: 15-427 m • Power: 3.7-63.4 kW • Speed: 1800-7600 rpm ClydeUnion Pumps: The ClydeUnion Pumps brand, part of Spillway, boasts world-leading proprietary technology for pump equipment, as well as expertise in hydraulic and engineering design. We are committed to serving our customers’ core markets and providing them with comprehensive global after-sales support. In 2008 and 2010, ClydePumps acquired Union Pumps and S&N Pumps respectively, and integrated them into ClydeUnion Pumps. Today, the professional team behind the ClydeUnionPumps brand is present around the world, and it boasts a robust global sales and service network dedicated to providing customers with high-quality pump products and services. The ClydeUnion Pump DB62c is a vertical, multistage, heavy-duty pump designed in accordance with the latest versions of API 610 and API 682. It is designed for low-temperature applications in liquefied gas transportation. The ClydeUnion Pumps vertical shaft pumps feature a barrel-shaped design along with a special \"C\"-shaped impeller, and are equipped with dual mechanical seals to effectively seal NGL, LNG, LPG, and other low-temperature fluids. Performance parameters: • Flow rate: 2,500 m3 per hour • Head: up to 3,000 m • Temperature: as low as -200°C • Rotation speed: up to 3,600 rpm • Flange drilling: ANSI or BS. EBARA America’s low-temperature pump division, Cryodynamics, was established in California in 1972. To realize the founder’s design concept for \"submersible motor pumps,\" in 1984, Cryodynamics partnered with Ebara International Corporation (the largest pump manufacturer in Japan, with over 5,000 employees). In 1989, cooperation with Ebara reached its peak, leading to the establishment of EIC’s cryopump division. The company’s founders became the managers of the new company and were actively involved in its daily operations. Therefore, the cryopump division maintained its leadership in the design, production, and testing of submersible motor pumps. By joining the Ebara Group, we can flexibly combine the technical advantages of submersible motor pumps with those of centrifugal pumps, along with our engineering experience dating back to 1912. This combination provides a profound technical background that no other cryogenic liquid pump manufacturer can match. Therefore, Cryodynamics has undoubtedly become the leader in this market. EIC is located in a modern 3,000-square-meter indoor facility in Sparks, Reno, Nevada, with a total area of 24,000 square meters. In 1994, EIC moved to a modern production facility built specifically for it in the local area. This facility includes the world’s largest test rig for cryogenic liquefaction pumps. We are the only manufacturer capable of providing full-performance testing of liquefied gas pumps using various liquid media. Tests on LNG, propane, or liquid nitrogen (LN2) are conducted at maximum flow rates and power levels, in accordance with the specified temperature and density of the medium. The pump and motor are integrally installed on the same shaft, without a dynamic seal. Therefore, there is no possibility of leakage, whether it is in operation or at rest; hence, there is no need to check for ice formation or leaks before starting up. This is particularly important for extracting cryogenic liquids. Since both the pump and the motor are submerged in the liquid medium for extended periods, the unit can be started immediately without any need for inspection. Placing the entire unit inside a suction vessel makes the installation process very simple and safe, in accordance with appropriate vessel pressure codes such as ASME VIII. The unit is identical to that in the factory – there is no coupling; no additional piping has been installed for seal cleaning, bearing cooling, or lubrication. Compared to traditional pumps, the cryogenic pumps produced by EIC are lightweight, low-noise, highly safe, and easy to install. Of course, the fact that no regular daily maintenance is required is a major advantage. Another feature of all the pumps produced by Ebara America’s low-temperature pump division is its unique \"thrust-balancing mechanical principle\", which fully balances the axial load on the pump bearings, allowing them to operate at full flow rate with no load. According to the American Electrical Code (Paragraph 501.8(A)(4) of NFPA 70-1987), the units are suitable for installation in Class 1, Div 1, Groups C and D locations; these locations typically require explosion-proof motors. Since the pumps from Ebara America Cryogenic Pumps can be installed inside the tank, all connections below the maximum liquid level can be eliminated. This eliminates the possibility of leaks within the main tank caused by pipes or joints. By reducing potential leaks, customers are allowed to reduce the size of the liquefied gas storage tank within the applicable specifications. The pumpable design of the EIC allows the unit to be safely removed from the operating gas tank without releasing vaporized liquefied gas into the atmosphere. Since the pump can be placed inside a large tank, the location of the large tank can be semi-underground or fully underground. • Flow rate: ~2000 m³/h • Dimensions: Φ25–Φ500 • Medium: LNG and LPG • Temperature: -165–0°C • Head: ~1800m Design features 1) Thrust-balancing mechanical device The illustration below shows the unique method employed by EIC’s cryogenic pumps to achieve complete balance of the axial hydraulic thrust between the pump stages. This extends the service life of the bearings in the product lubrication pump. 2) Lubrication and cooling system: The cooling of submersed stator motors and the lubrication of bearings are achieved through the static stress generated by the compressed product pressure and acting on the outer diameter of the impeller. The resulting flow passes through the wear ring at the top of the impeller, then through the lower bearing and the gap between the motor rotor and stator. The liquid flow serves for bearing lubrication and motor cooling. The upper bearing uses separate lubrication. The product flow passes through a very small orifice plate, then, together with the bearings and bearing retainers, enters the motor. Then it enters the main product pipeline rather than the pump inlet. For high-pressure pumps, the motor cooling return system will be changed so that the motor cooling flow follows a predetermined path through the intermediate impeller section before entering the outlet flow. 3) Bearing structure: All EIC cryopumps are equipped with stainless steel ball bearings, offering a minimum rated operating life of 25,000 hours and an accuracy grade of ABEC-1 level 3. The bearings will be specially modified, with custom-made non-metallic (Cryolon) components being used to replace the stainless steel bearing separators. The separator consists of two halves and is connected by rivets. 4) Design of low-temperature dynamic inducer wheels: The selection and design of inducer wheels are based on a large number of case studies of operating products in this field. This study enables the inducer wheel to perform as well in general industrial applications as it does in pumps used in the more demanding hydrocarbon industry. JC Carter is a leading manufacturer of electric submersible pumps for low-temperature applications, with numerous use cases in the growing natural gas market. The company’s products are primarily used in liquefied natural gas regasification plants, liquefaction equipment manufacturers, and the natural gas liquids processing industry. (In 2015, Nikkiso Cryo acquired JC Carter’s cryopump business from Atlas Copco; previously, Atlas Copco had acquired JC Carter’s cryopump business in March 2011.) ) The history of JC Carter dates back to 1947, when James Coolidge “Cool” Carter, the founder of JC Carter Company, used his expertise in the industry to begin manufacturing fuel pumps for rocket engines. Twelve years later, in 1959, Carter utilized his engineering experience in rocket fuel pumps to begin designing his first submersible pump. In 1961, he introduced the world’s first SMP for the rapidly growing LNG industry. His SMP technology has been widely praised for its originality and exquisite craftsmanship, making JC Carter a leader in the industry. For over 30 years, JC Carter’s first-generation pumps have been a symbol of innovation and superior craftsmanship in the LNG SMP sector. NIKKISO is a global leader in the field of submersible pumps for low-temperature applications, and it is also at the forefront in terms of canned pumps, which are primarily used in the chemical and processing industries. Nikkiso cryopumps are required for the transport of liquefied petroleum gas and liquefied natural gas (LNG), which must take place at extreme temperatures (for LNG, between -164 and -161 °C). For such applications, NIKKISO cryopumps are a reliable choice. Special low-temperature submersible motors eliminate the risk of leaks and simplify pump installation. The bearings feature a minimum-load design, thus ensuring a long service life. A variety of different models are available; for example, there are those installed inside storage tanks, which can be removed when installed in condensation vessels, as well as models that are fixedly installed within the tanks. In addition, through our pump testing facilities, we offer testing services using LNG (-162 °C). NIKKISO cryopumps offer a variety of performance options. The motor can be adjusted individually for specific applications. Drive unit parameters.

The pumpable design of the EIC allows the unit to be safely removed from the operating gas tank without releasing vaporized liquefied gas into the atmosphere. Since the pump can be placed inside a large tank, the location of the large tank can be semi-underground or fully underground. • Flow rate: ~2000 m³/h • Dimensions: Φ25–Φ500 • Medium: LNG and LPG • Temperature: -165–0°C • Head: ~1800m Design features 1) Thrust-balancing mechanical device The illustration below shows the unique method employed by EIC’s cryogenic pumps to achieve complete balance of the axial hydraulic thrust between the pump stages. This extends the service life of the bearings in the product lubrication pump. 2) Lubrication and cooling system: The cooling of submersed stator motors and the lubrication of bearings are achieved through the static stress generated by the compressed product pressure and acting on the outer diameter of the impeller. The resulting flow passes through the wear ring at the top of the impeller, then through the lower bearing and the gap between the motor rotor and stator. The liquid flow serves for bearing lubrication and motor cooling. The upper bearing uses separate lubrication. The product flow passes through a very small orifice plate, then, together with the bearings and bearing retainers, enters the motor. Then it enters the main product pipeline rather than the pump inlet. For high-pressure pumps, the motor cooling return system will be changed so that the motor cooling flow follows a predetermined path through the intermediate impeller section before entering the outlet flow. 3) Bearing structure: All EIC cryopumps are equipped with stainless steel ball bearings, offering a minimum rated operating life of 25,000 hours and an accuracy grade of ABEC-1 level 3. The bearings will be specially modified, with custom-made non-metallic (Cryolon) components being used to replace the stainless steel bearing separators. The separator consists of two halves and is connected by rivets. 4) Design of low-temperature dynamic inducer wheels: The selection and design of inducer wheels are based on a large number of case studies of operating products in this field. This study enables the inducer wheel to perform as well in general industrial applications as it does in pumps used in the more demanding hydrocarbon industry. JC Carter is a leading manufacturer of electric submersible pumps for low-temperature applications, with numerous use cases in the growing natural gas market. The company’s products are primarily used in liquefied natural gas regasification plants, liquefaction equipment manufacturers, and the natural gas liquids processing industry. (In 2015, Nikkiso Cryo acquired JC Carter’s cryopump business from Atlas Copco; previously, Atlas Copco had acquired JC Carter’s cryopump business in March 2011.) ) The history of JC Carter dates back to 1947, when James Coolidge “Cool” Carter, the founder of JC Carter Company, used his expertise in the industry to begin manufacturing fuel pumps for rocket engines. Twelve years later, in 1959, Carter utilized his engineering experience in rocket fuel pumps to begin designing his first submersible pump. In 1961, he introduced the world’s first SMP for the rapidly growing LNG industry. His SMP technology has been widely praised for its originality and exquisite craftsmanship, making JC Carter a leader in the industry. For over 30 years, JC Carter’s first-generation pumps have been a symbol of innovation and superior craftsmanship in the LNG SMP sector. NIKKISO is a global leader in the field of submersible pumps for low-temperature applications, and it is also at the forefront in terms of canned pumps, which are primarily used in the chemical and processing industries. Nikkiso cryopumps are required for the transport of liquefied petroleum gas and liquefied natural gas (LNG), which must take place at extreme temperatures (for LNG, between -164 and -161 °C). For such applications, NIKKISO cryopumps are a reliable choice. Special low-temperature submersible motors eliminate the risk of leaks and simplify pump installation. The bearings feature a minimum-load design, thus ensuring a long service life. A variety of different models are available; for example, there are those installed inside storage tanks, which can be removed when installed in condensation vessels, as well as models that are fixedly installed within the tanks. In addition, through our pump testing facilities, we offer testing services using LNG (-162 °C). NIKKISO cryopumps offer a variety of performance options. The motor can be adjusted individually for specific applications. Drive unit parameters.
