Cryogenic CDR Pumps: A New Production Challenge

Cryogenic applications represent a rapidly expanding sector for modern industry and a technological challenge for businesses. Handling fluids at very low temperatures, even below absolute zero, means confronting peculiar physical phenomena such as the extreme contraction of materials, the freezing of mechanical organs, and the instability of the fluids themselves. The Cryogenic pumps, In fact, they must be able to guarantee reliability, safety, and operational continuity even under highly critical thermal and pressure conditions.

These plants treat Liquid CO₂, nitrogen, industrial gases, or special mixtures used in strategic sectors such as industrial refrigeration, the food industry, environmental treatment, laboratory and research facilities, and energy technologies. Cryogenic pumps must therefore be designed to ensure complete fluid isolation, preventing leaks or contamination while maintaining consistent performance in complex environments.

Although it was not part of the original core business, the cryogenic pump sector has recently been embraced by CDR Pompe thanks to a flexible and strongly oriented approach to custom design with the custom pumps range. For over 40 years, the company has been developing customized solutions for the handling of critical fluids, offeringmagnetic drive and mechanically sealed pumps for the chemical, pharmaceutical, and process industries.

At CDR Pompe, we offer to customers not only highly reliable products but also Technical consulting, design support, after-sales assistance, and complete customization. A natural evolution for a company that makes quality and constant innovation its hallmark. 

Custom design, UST-B, and operational performance of cryogenic pumps

To respond to inquiries about cryogenic pumps, CDR has employed its Technical Office and R&D to reinterpret standard models, thereby introducing structural modifications. The project starts from a solid foundation it makes modifications to current versions suitable for low temperatures and the particular thermodynamic characteristics of cryogenic fluids. Each pump is adapted to the client's and system's needs thanks to customized configurations.

The heart of the CDR cryogenic proposal is the series UTS-B, close-coupled centrifugal pumps with magnetic drive The absence of mechanical seals reduces leakage risk and allows safe operation at low temperatures. Our customized cryogenic solutions offer:

• Operating temperature: up to –100 °C with external magnetic lantern and core in AISI316 (cryogenic execution).
• Maximum pressureup to 20 bar for liquid CO₂
• Managed fluid: specifically liquid CO₂, a compound increasingly used in cooling, inerting, and food processing systems.

Installation and Real-world Applications: Italy-Netherlands Synergy

Real-world installations confirm the effectiveness of the CDR cryogenic pump project. Thanks to the joint work between the Italian team and the international network, The UTS-B custom pumps have been successfully installed. in Italy and the Netherlands in systems operating with liquid CO₂. Our logistics network, spread across many European countries and beyond, guarantees direct assistance and maintenance, replicating the same quality of service even outside the national Italian borders.

The company designed this type of pump for cryogenic applications. to manage the handling of liquid CO₂ ensuring durability and reliability in critical contexts such as ATEX equipment and cryogenic cycles: 1’Accuracy in the transport of liquid CO₂ without leaks or pressure variations is indeed a strategic asset, especially in relation to increasingly stringent regulations and sophisticated processes. 

CDR value-added in special applications

Standard solutions are often insufficient to meet the needs of the cryogenic sector. Each application requires Detailed analysis, durable materials, custom solutions, and a production chain capable of ensuring precision and control at every stage. That is precisely why CDR Pompe continues to invest in technological innovation, materials research, and operational safety, Integrating engineering experience and in-house production with a consulting approach tailored to each client's specific needs.

Deep customization for cryogenic pumps, cutting-edge materials and magnetic technology

Each pump is designed starting from the real operating conditionsfluid type, pressure, temperature, viscosity, and installation environment. The geometries are adapted, as are the construction materials, to ensure maximum compatibility and durability. 

This variety allows you to to resist corrosive substances, high pressures, and low temperatures without compromising the seal. Furthermore, the Magnetic drive pump, avoiding the use of mechanical seals, they eliminate the risk of leaks and significantly reduce maintenance costs. An ideal choice for the Liquid CO₂ specifically, but also for all applications where security is the most important aspect.

Certified reliability and global, ongoing support

Every project can be realized according to ATEX directives and international standards such as ISO 9001. The pumps are tested internally, also with Attended tests, to ensure that performance is consistent with the required specifications. CDR then supports the client from the analysis phase through to installation, including abroad, as demonstrated by the installations in Italy and the Netherlands. our sales network spread across over 50 countries worldwide. The after-sales service is direct, competent, and responsive, with constantly growing international expansion, as evidenced by the recent AEO certification.

CDR Pompe has successfully addressed the energy and production needs of the modern market: from chemical and pharmaceutical production lines to innovation in the field of cryogenic applications. The UTS-B custom per CO₂ liquida – not only summarize the company's know-how, but also open up a new range of customization opportunities and customization. With installations already operational in Italy and the Netherlands, CDR represents a reliable and technologically advanced partner for companies seeking tailor-made, safe, and efficient solutions in extreme conditions.

Frequently Asked Questions

Which cryogenics pumps does it offer CDR Pompe for the handling of liquid CO₂?

CDR Pompe It proposes the UTS-B series in a custom version, consisting of monobloc centrifugal pumps magnetic drive. They are designed for liquid CO₂, used in cooling, inertization and food processing plants. They are based on established standard models modified by the technical and R&D department for low temperatures and the thermodynamic characteristics of cryogenic fluids.

At what temperature and pressure does a cryogenic UTS-B pump work for liquid CO₂?

The UTS-B cryogenically operated pump operates down to -100 °C and up to a maximum pressure of 20 bar with liquid CO₂. To achieve these conditions, it uses an AISI316 torch and external magnetic core. However, each configuration is verified based on the fluid, pressure, temperature, viscosity, and installation environment of the individual system.

Why is a pump magnetic drive without mechanical seals suitable for cryogenic applications?

A magnetic drive non-piston pump has no mechanical seals, so it eliminates the most prone to leakage point, especially at low temperatures where materials contract and mechanical parts risk freezing. This ensures fluid isolation, prevents contamination, and significantly reduces maintenance costs. It is a suitable choice for liquid CO₂ and applications where safety is a priority.

In which sectors and plants are cryogenic pumps used for liquid CO₂, nitrogen and industrial gases?

Cryogenic pumps are used in sectors such as refrigeration industrial, the food industry, environmental treatment, laboratories and research, and energy technologies. They move liquid CO₂, nitrogen, industrial gases or special mixtures. They must ensure tightness, the absence of contamination and constant performance. The UTS-B custom units CDR Pompe are already installed in CO₂ liquid systems in Italy and the Netherlands.

Can CDR cryogenics pumps be manufactured according to ATEX and certified to ISO 9001?

Yes, every project can be carried out in accordance with the ATEX directives and international standards, including ISO 9001. The pumps are tested internally, including with customer-attended tests, to verify that performance is consistent with the required specifications. Reliability also applies to ATEX systems and cryogenic cycles, where the integrity of liquid CO₂ is crucial.

CDR Pompe Do you offer assistance and support for cryogenic systems installed abroad?

Yes, we CDR Pompe follow the customer from analysis to installation, even abroad, as demonstrated by the UTS-B custom installations in Italy and the Netherlands.
