Nikkiso launches an innovative pump to revolutionize hydrogen fueling stations. Oct 28, 2026 - 10:12 Nikkiso, a Japan-based company with over six decades in industrial innovation, recently unveiled a groundbreaking product for hydrogen fueling infrastructure. The new P2KHF pump is pitched as a practical response to a persistent problem: loss of liquid hydrogen during transfer at fueling stations. Nikkiso says the device is intended to keep less hydrogen sent to waste, a claim that, if borne out in wider use, would alter operating margins for station owners and could change how operators think about on-site storage and transfer. During tests at an unspecified site in California, Nikkiso claims that the P2KHF managed to achieve liquid-hydrogen transfer losses of less than 1%. That single result sits at the center of the company's announcement. The pump serves dual roles - it can function as a boost pump or stand alone for subcooled liquid hydrogen refueling. Retrofit compatibility with select existing Nikkiso stations is also part of the pitch, a detail that could ease deployment by reducing the need for wholesale station rebuilds.

Alutal announces partnership with Nikkiso on cryogenic pumps. You will see in this article. Alutal has partnered with Nikkiso Clean Energy & Industrial Gases (Nikkiso CE&IG), one of the world's largest manufacturers of cryogenic pumps. With this agreement, Alutal will now offer Nikkiso's centrifugal and reciprocating cryogenic pumps in Brazil for liquefied oxygen, nitrogen, and argon, LNG, refrigerated LPG, CO2, and hydrogen. The partnership comes at a time of growth for the sector. An independent market study estimates the Brazilian market for cryogenic pumps at approximately US$51,9 million in 2026, with annual growth of around 6,7% until 2033. Today, Brazil is already the largest market in Latin America in this segment. What is a cryogenic bomb? A cryogenic pump is a device that transfers or pressurizes liquefied gases at very low temperatures. Liquid nitrogen, for example, is around -196 °C, while LNG is close to -162 °C. Under these conditions, the pump needs to block heat input, because any heating vaporizes the product and causes cavitation. There are two main types. Centrifugal pumps move large volumes with moderate pressure, which is why they are used in truck unloading, tank transfers, and terminals. Reciprocating piston pumps operate with lower flow rates and high pressure. Thus, they are the common choice for filling cylinders. There is also the submersible motor pump, which is immersed in the liquid itself. In this way, the fluid cools the motor and the pump does not require a shaft seal, an advantage in LNG and LPG terminals. Get to know Nikkiso. Nikkiso's history begins in Japan in the early 1950s with the manufacture of dosing pumps. In 1982, the company started producing cryogenic pumps with submersible motors. Soon after, in 1987, it incorporated JC Carter's technology for this type of equipment. Since 2019, this operation has been part of the Nikkiso Clean Energy & Industrial Gases Group. The group belongs to Nikkiso Co., Ltd., listed on the Tokyo Stock Exchange, and brings together more than 1.800 professionals in over 20 countries. The cryogenic pump portfolio has two lines. Nikkiso ACD originated in California, also in the 1950s, with pumps for liquid oxygen. Currently, it supplies centrifugal pumps for unloading trucks, transferring tanks, and process applications. It also produces reciprocating pumps for cylinder filling and high-pressure service. Nikkiso Cryo, on the other hand, manufactures submersible motor pumps for LNG, LPG, ethylene, liquid nitrogen, and propylene. Field data explains the brand's reputation. In many installations, these pumps exceed 20.000 hours between overhauls, and some have even surpassed 40.000 hours. Furthermore, more than 50 LNG-powered vessels operate with ACD pumps, more than with any other brand. Before leaving the factories in the United States and Japan, each pump undergoes performance testing with LNG, LPG, or liquid nitrogen. The test is conducted at actual speed, power, and flow rate. Similarly, the units comply with API and ASME standards and are ISO 9001 and ISO 45001 certified. Where cryogenic pumps serve the Brazilian market. Industrial gases remain the mainstay of demand in the country. Air separation plants produce liquid oxygen, nitrogen, and argon. This product then passes through tanks, trailers, and customer reservoirs before reaching the processing unit. Each stage may require a centrifugal or alternative pump. For this reason, this segment accounts for a significant portion of recurring purchases. LNG has opened a second front. According to a 2026 industry survey, Brazil already has seven LNG terminals in operation. At the same time, small-scale LNG transports gas by truck to regions without pipelines. There are also new refrigerated LPG terminals under development in the Northeast. The third front comes from biomethane. Plants that purify biogas from landfills and vinasse separate a stream of CO[2] that can become a commercial product. To sell this CO[2], however, the plant needs to liquefy, store, and transfer the product using liquid CO[2] pumps. Alutal technical support for cryogenic pumps. Alutal has been active in industrial instrumentation since 1994 and represents international manufacturers of flow measurement, analysis, and control equipment in Brazil. Now, Nikkiso joins this portfolio with a line that covers almost the entire cryogenic chain. This includes pumps for unloading trucks and filling cylinders, as well as models with submersible motors and marine pumps. How Alutal helps you choose the right cryogenic pump. Choosing a cryogenic pump requires considering the fluid, flow rate, discharge pressure, and operating regime. A cylinder filling pump, for example, operates at high pressure and low flow rate. In contrast, a truck discharge pump needs a high flow rate with minimal product loss. Therefore, the analysis begins with process data. Alutal's technical team gathers temperature, suction and discharge pressure, available NPSH, and whether the operating regime is continuous or intermittent. After collecting this information, they compare Nikkiso models and recommend the correct configuration: centrifugal, reciprocating, or with a submersible motor. All service is provided in Portuguese, with local support. Nikkiso pumps are available on the Alutal website. The Alutal website already compiles Nikkiso models, with technical descriptions and specifications for each pump. This allows you to learn about all Nikkiso cryogenic pumps and compare options by application. Among the models are: * Truck unloading: AC-14/14M, TOP series, CPLH, TC-21 (HD/J) and DCP-VFD, with inverter; * Cylinder filling: P2K, ACPD, NOVA, P1100, RPSA and SGCL 41.3; * High flow rate and high pressure: 3-GUPD and SLS, for oil wells and nitrogen purging; * Submersible motor: TC-34 and TC-34.2; * Maritime application: MSP-GU and MSP-SL, for ship provisioning; * Liquid CO[2]: DCPS, for transfer. If your plant works with liquefied gases, talk to the experts at Alutal to determine the right cryogenic pump for the process. Frequently asked questions about cryogenic pumps. What is a cryogenic pump used for? It transfers or pressurizes liquefied gases, such as oxygen, nitrogen, argon, LNG, refrigerated LPG, and CO[2]. In practice, the pump unloads tankers, feeds vaporizers, and fills high-pressure cylinders. What is the difference between a centrifugal cryogenic pump and a reciprocating pump? A centrifuge moves large volumes with moderate pressure, while the alternative generates high pressure with a lower flow rate. Therefore, the first is suitable for transfer and discharge, and the second for filling cylinders. What fluids can Nikkiso cryogenic pumps handle? The ACD and Cryo lines cover liquid oxygen, nitrogen, and argon. They also handle LNG, LPG, ethylene, propylene, CO[2], and hydrogen. How long does a Nikkiso cryogenic pump operate between overhauls? According to the manufacturer, many installations exceed 20.000 hours between overhauls. Some units have even surpassed 40.000 hours. Where can I buy Nikkiso cryogenic pumps in Brazil?
