CGA P-48 – Reciprocating Cryogenic Pumps and Pump Installations for Oxygen, Argon, and Nitrogen

Reciprocating cryogenic pumps have become key components within the industrial gas industry handling primarily, liquid oxygen, argon, and nitrogen. To ensure that pumps operate both safely and reliably, it is important that pumps are correctly designed, installed, operated, and maintained for the required duty.

Pumping cryogenic fluids is accompanied by some degree of hazard. The hazards include liquid under pressure, cryogenic temperatures, volume and pressure increases due to vaporization, and the ability of oxygen to accelerate combustion.

This publication gives guidance to manage these hazards.

This publication is intended to cover cryogenic reciprocating pumps and installations for liquid oxygen, argon, and nitrogen.

The publication contains a summary of industrial practices and is based on the combined knowledge, experience, and practices of industrial gas and equipment suppliers.
