The high-pressure liquid nitrogen (LN₂) Reciprocating pump serves as the core power unit of high-pressure LN₂ skids, specifically engineered and designed for the high-pressure transportation of ultra-low temperature LN₂ at -196℃. Featuring a precision Reciprocating mechanism, its key components are crafted from low-temperature resistant, high-strength alloy and special sealing materials, complemented by an intelligent pressure regulation system and multiple safety protection mechanisms. This enables stable and precise delivery under high-pressure operating conditions. With its modular design, the pump seamlessly adapts to the integration requirements of skid-mounted equipment, boasting rapid startup, low pulsation, and high pressure control accuracy. Widely applied in scenarios such as oilfield LN₂ fracturing, gas lift operations, and industrial high-pressure gas supply, it stands as a reliable power guarantee for the efficient operation of high-pressure LN₂ skids.
