ISO 24490:2016 specifies the minimum requirements for the design, manufacture and testing of pumps for cryogenic service. ISO 24490:2016 is applicable to centrifugal pumps. However, it can be applied to other types of cryogenic pumps (e.g. reciprocating pumps), where applicable. This International Standard also gives guidance on the design of installations (see Annex A). It does not specify requirements for operation or maintenance. NOTE For cryogenic fluids, see ISO 21029‑1, ISO 20421‑1 and/or ISO 21009‑1.

Overview

ISO 24490:2016 - Cryogenic vessels - Pumps for cryogenic service specifies minimum requirements for the design, manufacture and testing of pumps intended for cryogenic service. It is primarily applicable to centrifugal pumps but can be applied to other pump types (for example, reciprocating pumps) where relevant. The standard also includes informative guidance on installation design (Annex A) and lists acceptable materials for liquid oxygen (LOX) service (Annex B). ISO 24490:2016 covers technical safety and conformity aspects but does not specify operational or maintenance procedures.

Key topics and technical requirements

ISO 24490:2016 addresses the following core technical areas relevant to cryogenic pumps:

Scope and applicability

Minimum requirements for pumps for cryogenic service (mainly centrifugal pumps).

Materials

Selection for low-temperature mechanical performance and toughness (references ISO 21028-1/2).
Atmospheric corrosion resistance and allowances.
Oxygen and oxidizing-fluid compatibility (requirements per ISO 21010; special materials guidance for LOX).
Hydrogen compatibility and risk of embrittlement (references ISO 11114 series).

Design requirements

Pressure-containing parts designed for nominal outlet pressures.
Hydraulic performance and duty-point considerations.
Clearances, prevention of rubbing, and fastenings.
Bearing design (warm and cold bearings), bearing lubrication, and shaft seals.
Purging, prevention of particle contamination, flammable-liquid-specific provisions, and over‑pressurization protection.
Pump motors and integration with system installations.

Testing and verification

Prototype testing: design evaluation, performance evaluation, cryogenic tests.
Production testing: hydrostatic pressure tests, mechanical running and performance tests (reference ISO 5198 for hydraulic performance testing).

Cleanliness and marking

Cleanliness requirements specific to cryogenic systems (see ISO 23208).
Mandatory marking information and traceability.

Installation guidance and LOX material lists

Annex A: guidance for installation design.
Annex B: acceptable materials for centrifugal pumps used with liquid oxygen.

Practical applications

ISO 24490:2016 is directly applicable to equipment and systems handling cryogenic fluids such as liquid oxygen, liquid hydrogen, LNG and other industrial cryogens. Typical applications include:

Industrial gas production and distribution

Cryogenic storage and transfer systems

Aerospace and rocket propellant handling

Research laboratories and cryogenic test facilities

Petrochemical and LNG plant pumping systems
