Information

Different from general-purpose pumps, cryopumps need to keep low temperature during liquid delivery to minimize cold loss, otherwise cryopumps will fail to work due to the vaporization of the liquid. Due to working under low temperature conditions, the material, structure, operation and installation of the pump are different from general pumps.

Cryogenic liquid pump

Cryogenic liquid pumps are machines used to transport cryogenic liquids and increase their pressure. According to the principle of action, cryopumps can be divided into two categories: vane type and reciprocating type. The vane type includes centrifugal, mixed flow and axial flow. The reciprocating type has a plunger type and a piston type.
Centrifugal pumps are the most commonly used type of vane type. Centrifugal has single-stage and multi-stage points. The plunger pump is the most commonly used one in the reciprocating type, and it is divided into single-row and multi-row.
Centrifugal cryopumps are mostly used for low and medium pressure transportation. Column cryopumps are used in systems with high pressure and low flow.
