Pumps-Shaft Sealing Systems for Centrifugal and Rotary Pumps, Third Edition (Printed Edition Includes binder) (Includes Errata)
Edition: 3rd
American Petroleum Institute / 01-Sep-2004 / 195 pages

Includes November 2006 Errata.

Standard 682 specifies requirements and gives recommendations for sealing systems for centrifugal and rotary pumps used in the petroleum, natural gas and chemical industries. It is applicable to hazardous, flammable and/or toxic services where a greater degree of reliability is required for the improvement of equipment availability and the reduction of both emissions to the atmosphere and life-cycle sealing costs. It covers seals for pump shaft diameters from 20 mm (0.75 in) to 110 mm (4.3 in).

This Standard is also applicable to seal spare parts and can be referred to for the upgrading of existing equipment. A classification system for the seal configurations covered by this International Standard into categories, types, arrangements and orientations is provided.

This edition of API Std 682 is the identical national adoption of ISO 21049, Pumps - Shaft sealing systems for centrifugal and rotary pumps.
