Cryogenic Helium Pump

Product Overview

The Cryogenic Helium Pump is a key piece of equipment designed for the transfer of liquid or gas–liquid two-phase cryogenic media under extremely low-temperature conditions. It enables stable and efficient fluid transport in cryogenic environments.

The pump mainly consists of a motor, drive shaft, flow components, thermal insulation structure, bearings, and sealing systems. Through start–stop control and variable frequency regulation, the pump can achieve stable cryogenic fluid delivery and precise flow control.

It is suitable for liquid helium, liquid hydrogen, liquid nitrogen, and LNG systems, serving as an essential component in cryogenic circulation systems and cryogenic transfer systems. The equipment is widely used in scientific research, energy engineering, and industrial cryogenic applications.

Working Principle

The cryogenic helium pump generally operates based on the centrifugal pumping principle. The motor drives the impeller through a rotating shaft at high speed, generating centrifugal force that converts kinetic energy into pressure energy, enabling continuous and stable fluid transport.

The pump body adopts an efficient thermal insulation structure to minimize heat ingress from the external environment, thereby reducing the vaporization loss of cryogenic media. To adapt to extremely low-temperature operation, the bearing and sealing systems are specially optimized, ensuring long-term reliable performance in cryogenic conditions.

With the integration of a variable frequency control system, the pump can precisely adjust flow rate and head, meeting the requirements of various operating conditions.
