Description Vendor

The BNHP-29 Liquid Hydrogen Pump is a process pumps product from Barber-Nichols for hydrogen and fuel-cell system applications. Its specified configuration includes Partial-emission centrifugal pump; hermetic design with no dynamic seals; air-cooled motor; variable-speed control; CE mark with ATEX rating. Its principal deployment contexts include liquid-hydrogen transfer systems and lh2 delivery to aircraft. The technical design also includes partial-emission centrifugal pump architecture, hermetic design with no dynamic seals, thin-wall design to minimize heat leak, vacuum housing allows pump removal for maintenance without breaking the cold-box vacuum. Its documented capability set includes pumps and transports liquid hydrogen; varies pump speed to adjust head and flow; contains the process fluid in a hermetic no-dynamic-seal design. For system designers evaluating process pumps, these details define the model's operating values, physical or control characteristics, and the functions available for integration into the relevant hydrogen process or electrochemical system. The product can also be applied in lh2 delivery to ships, with selection based on the stated specifications and the surrounding system requirements.

Use Cases

  • Liquid-hydrogen transfer systems
  • LH2 delivery to aircraft
  • LH2 delivery to ships
  • Cryogenic hydrogen transport and compression duties

Capabilities

  • Pumps and transports liquid hydrogen
  • Varies pump speed to adjust head and flow
  • Contains the process fluid in a hermetic no-dynamic-seal design
  • Allows pump maintenance without breaking the cold-box vacuum
  • Operates with an air-cooled motor
Barber-Nichols, Inc. Barber-Nichols, Inc. designs and manufactures specialized turbomachinery for demanding fluid and gas applications. Its verified hydrogen products in this batch include a liquid-hydrogen centrifugal pump and hydrogen recirculation blowers for fuel-cell systems.
