Cryogenic Reciprocating Pump | Product Introduction

Our cryogenic reciprocating pump is a high-precision positive displacement fluid transfer equipment, specially developed for the safe and efficient transfer of cryogenic liquids (operating temperature typically below -150°C), including liquid oxygen, liquid nitrogen, liquid argon, LNG, liquid hydrogen and liquid helium. It is widely used in aerospace, energy, metallurgy, medical and other fields, providing reliable fluid handling solutions for ultra-low temperature working scenarios.

Core Design & Working Principle

Driven by electric motor, hydraulic system or pneumatic actuator, the pump adopts a reciprocating working principle: the piston/plunger makes linear reciprocating motion in the cylinder to change the volume of the pump chamber, and the one-way action of the inlet and outlet valves realizes the stable suction and discharge of cryogenic media. To adapt to ultra-low temperature conditions, key components are made of cryogenic-resistant materials (304/316L stainless steel, nickel-based alloys, aluminum alloys), matched with professional thermal insulation structures, sealing systems and cold compensation devices, ensuring stable operation in extreme environments.

Key Advantages

High Precision & Stability: Positive displacement structure ensures stable flow with little fluctuation, suitable for precise metering and transfer.

Extreme Environment Adaptability: Low NPSH design effectively prevents cryogenic liquid cavitation and vaporization; capable of safe operation under ultra-low temperature and high pressure (max outlet pressure up to 150.0MPa).

Reliable & Durable: Mature structural design, service life up to 20 years; high-vacuum jacket pump head (vacuum degree up to 10⁻⁵ Torr) reduces cold loss; sealing components have long service life (packing: 150,000 times/cylinder; piston ring: 300,000 times/cylinder).

Safe & Easy to Maintain: Equipped with multiple safety protection functions (overpressure protection, dry running prevention, low temperature leakage alarm); compact structure, routine maintenance can be completed in 2 hours, optional skid-mounted integrated design for outdoor use.

Energy Efficient: High volumetric efficiency, low noise and vibration, suitable for both continuous and intermittent working conditions, supporting stepless flow regulation.
