Cryogenic Pumps

Cryogenic Pumps by PBS

Cryogenic pumps are designed to deliver liquefied inert gases.
  • Compact design
  • Option of connecting an intercooler
  • High efficiency
  • Long serviceability and maintenance-free operating period
PBS has a long history of over 30 years in the cryogenic technology field as a supplier of key components, including cryogenic pumps. PBS centrifugal pumps are primarily designed for transporting liquefied inert gas (helium, nitrogen, argon, air, etc.) to a cryogenic device.

The flow units are always designed individually based on parameters specified by the customer.

The pump is designed modularly with two lines of standardized casings for different working media parameters and impeller sizes. The pump is driven by an electric engine defined by the customer.

Gas-dynamic bearing technology ensures trouble-free and maintenance-free operation. The developed drive offers power up to 7 kW.

Our cryopumps work in tandem with our cryogenic compressors and cryogenic turboexpander, performing a vital role in the entire cryogenic process of compressing, trapping, delivering and extracting energy as gases expand. 

The cryopumps are supplied to various industries and leading manufacturers in the world, including CERN research centre and LINDE, a leading global industrial gases and engineering company. Our cooperation with them has allowed PBS to develop trouble-free and maintenance-free operations of the devices with higher added value.

Why us?

Designed according to customer requirements

Designed according to customer requirements

The parameters of PBS cryogenic pumps are always adapted to specific customer requirements. PBS cryogenic pumps have been used primarily in research institutions in Europe and the US. 
Long life and durability

Long life and durability

PBS's cryogenic pumps are recognized for their durability and long serviceability while still maintaining a high level of performance efficiency.

Cryogenic technology services

PBS provides direct and indirect support for all of its cryogenic products during installation, commissioning and after-sales service.

Our efforts can be seen having a large impact on many fields, such as the medical field through magnetic resonance, tissue and organ preservation, and liquid gases; in the field of research with particle accelerators, laser research, superconductivity, superfluidity and low temperature research itself; space, where liquefied gases serving as fuel, as well as in space research; and also in mechanical engineering for the low-temperature stabilization of components, cooling of workpieces with liquid nitrogen among others.

Our services to our customers include not only the supply of such products, but also servicing of these parts, the majority of which occurs in the customer's facility, if necessitated. We also offer professional technical training for service personnel.
