Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 13709 was prepared by Technical Committee ISO/TC 115, Pumps, Subcommittee SC 3, Installation and

special application, in collaboration with Technical Committee ISO/TC 67, Materials, equipment and offshore

structures for petroleum, petrochemical and natural gas industries, SC 6, Processing equipment and systems.

Introduction

This International Standard was developed from API Standard 610, 8 edition, 1995, with the intent that the

9 edition of API 610 will be the same as this International Standard.

Users of this International Standard should be aware that further or differing requirements may be needed for

individual applications. This International Standard is not intended to inhibit a vendor from offering, or the

purchaser from accepting alternative equipment or engineering solutions for the individual application. This

may be particularly appropriate where there is innovative or developing technology. Where an alternative is

offered, the vendor should identify any variations from this International Standard and provide details.

Annex A specifies calculations for specific speed and suction-specific speed.
Annex B contains schematic drawings of cooling water and lubrication systems.
Annex C specifies requirements for hydraulic power recovery turbines.
Annex D specifies requirements for standard baseplates.
Annex E contains an inspector's checklist.
Annex F specifies criteria for piping design.
Annex G give guidance on material class selection.
Annex H specifies requirements and gives guidance on materials selection.
Annex I specifies requirements for lateral analysis.
Annex J specifies requirements for determining residual unbalance.
Annex K contains seal chamber runout illustrations.

Annex L contains forms which may be used to indicate vendor drawing and data requirements.

Annex M contains forms which may be used to record test data.
Annex N contains data sheets which purchasers are encouraged to use.

A bullet (•) at the beginning of a clause or subclause indicates that either a decision is required or further

information is to be provided by the purchaser. This information should be indicated on data sheets or stated

in the enquiry or purchase order (see examples in Annex N).

In this International Standard, where practical, US Customary units are included in brackets for information.
