recommendations for sealing systems for centrifugal
and rotary pumps used in petroleum, natural gas, and
chemical industries. It has been written mainly for
hazardous, flammable and/or toxic services where a
greater degree of reliability is required for the
improvement of equipment availability,the reduction
of both emissions to the atmosphere and life cycle
sealing costs. It covers seals for shaft diameters
from 20mm (0,75in.) to 110Êmm (4,3in.). This
Standard also applies to seal spare parts and can be
referred to for the upgrading of existing equipment. |
