Product Overview

The Submersible Centrifugal Pump (also called a sump pump) is designed for cryogenic and low-temperature liquid transfer, including liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), ethylene, and LPG.

The pump is fully submerged in the liquid during operation, providing stable flow and head. Its compact, reliable design ensures continuous, high-efficiency operation in low-temperature environments, making it ideal for deep liquid extraction and industrial cryogenic applications.

Working Principle

The pump operates with a motor-driven impeller submerged in the liquid, generating centrifugal force that accelerates the fluid from the center of the impeller outward. The guide vanes convert velocity energy into pressure energy, achieving efficient liquid transfer.

The submersible designeliminates the need for external suction piping, improving pumping efficiency and reducing cavitation risks.
Pump body and sealing systemsare made from cryogenic-resistant materials with optional explosion-proof designs, ensuring safe operation in flammable or low-temperature media.
