Pumps Shaft sealing systems for centrifugal and rotary pumps - CORR 15677: July 31, 2006
N BS EN ISO 21049
Annotation
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.

Насосы. Системы уплотнения волн центробежных насосов и вращающихся насосов поршня - CORR 15 677: July 31, в 2006
Этот Международный стандарт определяет требования и дает рекомендации для запечатывания систем для центробежных и роторных насосов, используемых в нефти, природном газе и химических промышленностях. Это применимо в основном для опасных, огнеопасных и/или токсичных услуг, где большая степень надежности требуется для улучшения доступности оборудования и сокращения обеих эмиссии к атмосфере и затратам на запечатывание жизненного цикла. Это покрывает изоляции для диаметров вала насоса от 20 мм (0,75 в) к 110 мм (4,3 в).
