PRODUCT NO. CX61011
This International Standard specifies requirements for
centrifugal pumps, including pumps running in reverse as
hydraulic power recovery turbines, for use in petroleum,
petrochemical and gas industry process services.
This International Standard is applicable to overhung pumps,
between-bearings pumps and vertically suspended pumps (see
Table 1). Clause 9 provides requirements applicable to specific
types of pump. All other clauses of this International Standard
are applicable to all pump
t
ypes. Illustrations are provided of the
various specific pump types and the designations assigned to
each specific type.
Relevant industry operating experience suggests pumps
produced to this International Standard are cost effective when
pumping liquids at conditions exceeding any one of the
following:
discharge pressure (gauge) 1 900 kPa
(275 psi; 19,0 bar)
suction pressure (gauge) 500 kPa
(75 psi; 5,0 bar)
pumping temperature 150 °C (300 °F)
rotative speed 3 600 r/min
rated total head 120 m (400 ft)
impeller diameter, overhung pumps 330 mm (13 in)
NOTE For sealless pumps, reference can be made to API Std 685. For
heavy duty pump applications in industries other than petroleum,
petrochemical and gas processing, reference can be made to ISO 9905.
