Product Overview

The Small-Size Cryogenic Submersible Centrifugal Pump is a high-efficiency pump designed for low-temperature liquid transfer. Featuring a submersible structure, it can be directly immersed in cryogenic media such as liquefied natural gas (LNG), liquid nitrogen (LN₂), and liquid argon (LAr), ensuring safe, stable, and efficient transfer. Its compact size and simple operation make it ideal for space-constrained cryogenic applications.

Working Principle

The pump operates via a motor-driven impeller, which accelerates the cryogenic liquid through centrifugal force. The pump’s guide structure converts velocity energy into pressure energy, achieving efficient fluid transfer.

The pump body and sealing systemare made from low-temperature and corrosion-resistant materials, allowing long-term stable operation under extreme cryogenic conditions.
The submersible designenables direct immersion in the liquid, improving transfer efficiency and reducing energy loss.
