By ISO/TC 67/SC 6
ISO 13709:2003 specifies standards for centrifugal pumps, together with pumps working in opposite as hydraulic strength restoration generators, to be used in petroleum, petrochemical and gasoline technique companies. ISO 13709:2003 is appropriate to overhung pumps, between-bearings pumps and vertically-suspended pumps. Clause eight offers specifications acceptable to express different types of pump. All different clauses of ISO 13709:2003 are appropriate to all pump forms. Illustrations are supplied of a few of the particular pump forms and the designations assigned to every particular variety. ISO 13709:2003 isn't really acceptable to sealless pumps.

B) Bearings shall be mounted directly on the shaft. Bearing carriers are acceptable only with purchaser approval. c) Bearings shall be located on the shaft using shoulders, collars or other positive locating devices. Snap rings and spring-type washers are not acceptable. d) The device used to lock thrust bearings to shafts shall be restricted to a nut with a tongue-type lock washer. NOTE This subclause applies to all rolling-element bearings, including both ball and roller types. For certain roller bearings, such as cylindrical roller types with separable races, bearing-housing diametral clearance may not be appropriate.
5 Ball thrust bearings shall be of the paired single-row, 40° (0,7 rad) angular contact type (7 000 series) with machined brass cages. Non-metallic cages shall not be used. Pressed steel cages may be used if approved by the purchaser. Unless otherwise specified, bearings shall be mounted in a paired arrangement installed back-to-back. The need for bearing clearance or preload shall be determined by the vendor to suit the application and meet the bearing life requirements of Table 9. NOTE There are applications where alternative bearing arrangements may be preferable, particularly where bearings operate continuously with minimal axial loads.
The gasket shall be of the controlled compression type, for example an O-ring or a spiral-wound gasket, with a metal-to-metal joint contact. If space or design limitations make this requirement impractical, an alternative seal gland design shall be submitted to the purchaser for approval. 1 General The topics of critical speed and lateral analysis are covered in the subclause dealing with each specific pump type. 1 Unless otherwise specified, a torsional analysis shall be performed by the manufacturer having unit responsibility if the driver is one of the following: a) electric motor, or turbine, through gear rated 1 500 kW (2 000 hp) or higher; b) internal combustion engine rated 250 kW (335 hp) or higher; c) synchronous motor rated 500 kW (670 hp) or higher; d) electric motor with variable-frequency drive (VFD) rated 1 000 kW (1 350 hp) or higher.
