Cryogenic Piston Pump

Description

Review

Product Overview

This reciprocating cryogenic piston pump is crafted for the secure and effective transfer of cryogenic liquids such as liquid nitrogen (LN₂), oxygen (LO₂), argon (LAr), liquefied natural gas (LNG) and carbon dioxide (LCO₂). It finds extensive use in cylinder filling stations, cryogenic storage facilities, and gas distribution networks across industrial, medical, and energy sectors.

Key Features

Wide-Ranging Compatibility: Capable of handling LN₂, LO₂, LAr, LNG and LCO₂, making it suitable for diverse cryogenic applications.
Variable-Speed Technology: Equipped with frequency control, it offers adjustable flow rates to meet different operational requirements.
Enhanced Safety Mechanisms:
- Safety valve alignment to prevent over-pressure situations.
- Back gas temperature interlock to avoid temperature-related malfunctions.
- Outlet gas pressure interlock for safe pressure management.
High-Efficiency Performance: A filling rate spanning from 50 to 5,000 L/H ensures quick and efficient liquid transfer.
Robust Construction: Constructed with stainless steel components, it can withstand the extremely low temperature of −196°C.

Certifications

Compliant with China GB 150 or CE PED 2014/68/EU standards.
ISO 9001:2015 certified for its quality management system.
