Cryogenic liquid pumps

Content

The cryogenic liquid pump is a single-cylinder reciprocating pump with the characteristics of compact structure, small size, light weight, large displacement, high pressure and small net suction pressure head. The working part of the pump consists of a cylinder, a piston, a piston rod, a sealing group, an inlet and outlet valve, etc.

The cylinder of the pump is the main container for inlet and outlet liquids. It is in a low temperature state and is insulated by a vacuum jacket to keep the liquid inside it at a low temperature for a long time. All parts are made of chromium-nickel austenitic stainless steel with good low temperature performance and low thermal conductivity.

Liquefied natural gas, or LNG for short, is natural gas that has been cooled to a liquid condition for convenient storage and transit. Using cryogenic heat exchangers, natural gas is liquefied when cooled to roughly -260°F (-161.5°C), making it easier to handle.
