This International Standard 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
mainly for 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 International 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.
