IS 15657:2021/ ISO 13709
Centrifugal pumps for petroleum, petrochemical and natural gas industries
Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.
This 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 Standard is applicable to overhung pumps, between-bearings pumps and vertically suspended pumps. Clause 9 provides requirements applicable to specific types of pump. All other clauses of this Standard are applicable to all pump types. Illustrations are provided of the various specific pump types and the designations assigned to each specific type.
Mechanical Engineering Department vide its Technical Committee MED 20 “Pumps Sectional Committee” has published several standards in the field of Standardization in different type of pumps, for example: Agricultural and Domestic Pumps, Utility and Industrial Application Pumps.
This Standard helps organizations to identify, track and improve their competitiveness by improving efficiency, performance and associated energy costs. Each organization can determine the best approach to adopt the requirements of IS 15657.
