Continuous Operation Cryogenic Reciprocating Pump

Product Overview

The Continuous Operation Cryogenic Reciprocating Pump is a high-efficiency pumping system designed for the stable transfer of cryogenic liquids such as liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX).

The pump is capable of maintaining stable flow rate and pressure output during long-term continuous operation, making it ideal for industrial applications that require uninterrupted cryogenic liquid delivery. With its robust construction and reliable performance, the pump ensures safe and efficient operation in demanding low-temperature environments.

Working Principle

The pump operates through a crankshaft and connecting rod mechanism that drives the piston in a reciprocating motion. During operation, cryogenic liquid is periodically drawn into the pump chamber and compressed.

During the compression stroke, the liquid is gradually pressurized and discharged through the outlet valve into the pipeline system, achieving stable high-pressure delivery.

The pump body is manufactured with cryogenic-resistant materials and a high-reliability sealing system, ensuring stable performance under extremely low temperatures. Optimized flow channel design reduces energy loss and improves overall transfer efficiency.
