Product Overview

The High-Pressure Piston Pump is specifically designed for high-pressure transfer of cryogenic liquids and gases, including liquefied natural gas (LNG), liquid nitrogen (LN₂), liquid argon (LAr), and liquid oxygen (LOX).

This pump delivers extremely high outlet pressure, meeting industrial demands for high-pressure, high-flow transfer. With a robust structure and stable operation, it ensures efficient performance under long-term continuous operation, making it an ideal choice for petrochemical, energy, and research applications requiring high-pressure cryogenic delivery.

Working Principle

The high-pressure piston pump operates via a motor-driven crankshaft and connecting rod mechanism, driving the piston to move reciprocally within the pump cylinder.

During the suction stroke, cryogenic liquid or gas enters the pump chamber.
During the compression stroke, the medium is pressurized and discharged through the outlet valve, achieving stable high-pressure delivery.

Pump body and sealing systems use low-temperature-resistant materials to ensure safe and stable operation in cryogenic conditions. Multi-stage designs or parallel pump configurations allow continuous delivery and high-pressure output according to flow requirements, adapting to complex process conditions.
