Long-Cycle Low-Temperature Centrifugal Pump

Product Overview

The Long-Cycle Low-Temperature Centrifugal Pump is designed for high-reliability transfer of cryogenic liquids, including liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX).

This pump ensures stable flow and head during extended continuous operation, making it ideal for industrial, energy, and research applications where long-term, uninterrupted low-temperature liquid transfer is critical. Its robust construction and cryogenic-resistant materials guarantee long-term operational stability.

Working Principle

The pump operates via a motor-driven impeller that accelerates liquid from the pump center outward using centrifugal force. The guide vanes convert velocity energy into pressure energy, achieving stable liquid delivery.

• Pump bodyis constructed with low-temperature resistant materials.
• Gas labyrinth sealseffectively prevent leakage and minimize maintenance requirements.
• Multi-stage impeller designs or optimized pump structures allow adaptation to various flow rates and head requirements, maintaining stability under extreme cryogenic conditions.
