Product Overview

The Intermittent Operation Cryogenic Centrifugal Pump is a high-efficiency pump specifically designed for low-temperature liquid transfer, including liquefied natural gas (LNG), liquid nitrogen, liquid argon, and liquid oxygen.

Engineered for harsh operating environments, the pump provides high flow and high head, making it ideal for intermittent operation industrial scenarios while ensuring safe and reliable liquid transfer.

Working Principle

This pump utilizes a multi-stage centrifugal design. Rotating impellers generate centrifugal force, drawing low-temperature liquid from the inlet and compressing it to the outlet for efficient liquid transfer.

Mechanical seals prevent leakage and ensure long-term stable operation at cryogenic temperatures. The pump body is made of low-temperature-resistant materials and supports intermittent operation. Additionally, it is equipped with a explosion-proof motor and safety control system, ensuring safe operation in flammable or explosive media.

Key Features

High Efficiency:Maximum flow up to 1250 m³/h with high head to meet diverse cryogenic liquid transfer requirements.
Mechanical Sealing:Advanced mechanical seal design prevents leakage, ensuring long-term reliability.
Long-Term Continuous Reliability:Designed for over 20,000 hours of operation, delivering sustained performance.
Explosion-Proof Motor:Safe for operation in flammable or explosive environments.
