High-Pressure Piston Pump

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.
