Cryogenic Pump

Cryogenic pumps are the types of pumps which are designed to move coolants and cryogenic liquids. These pumps are built to withstand and operate in extremely cold temperatures.

Uses and Features of Cryogenic Pump:

• These pumps feature hermetically sealed designs to minimize heat leakage from the motor or contamination by process fluids into the cryogenic fluid.
  
  
• There are long shaft cryogenic pumps that may be welded or bolted to a variety of cryogenic equipment, including dewar and cryostat. A dewar is a specially insulated container designed to store liquefied gases such as the liquid nitrogen used as a coolant in cryogenic applications. A cryostat is a device which is used to maintain the temperature of the coolant.
  
  
• A centrifugal cryogenic pump is typically used to transfer cryogenic liquids between a storage tank or tanker car because of its ability to produce and maintain a high flow rate.
  
  
• There is submersible cryogenic pump which is used as a pump in vehicles that use liquefied natural gas or in the liquid hydrogen propellant system in a rocket.
  
  
• Cryogenic pumps are usually constructed with a vacuum housing to provide a barrier between the motor and the cryogenic fluid for use in extremely cold environments.
  
  
• These pumps are used to circulate coolant in a variety of applications which also include cooling high temperature superconducting cables or magnets, for cooling synchrotron beamline crystals, and as pumps in prototype slush hydrogen applications.
