Standards for Fossil Power Plant Pumps

By Hydraulic Institute

Q What standards are applied to fossil power plant pumps?

A Specifications for power plant pumps will invoke many standards and requirements that will vary based on the specifier. A specific design standard is not applied.

Pump manufacturers that supply to this industry have developed product lines designed to internal standards to meet the reliability and pricing requirements that the market demands. Sometimes American Petroleum Institute (API) design standards are applied or pumps complying with API standards are specified in the power gen industry.

Regarding the performance, testing and application of the pumps, Hydraulic Institute (HI) standards and , Hydraulic Institute (HI) standards and guidebooks can also be applied as follows:

• Important application considerations, pump types and typical materials of construction that are used in typical fossil power plant pump applications can be found in HI’s Pump Application Guidebook for Power Plant Pumps.

• Guidelines for the measurement of airborne sound can be found in ANSI/ HI 9.1-9.5 Pumps – General Guidelines.

• Guidelines on the application of net positive suction head (NPSH) margin and the preferred and allowable operating region can be found in ANSI/HI 9.6.1 Rotodynamic Pumps – Guideline for NPSH Margin and ANSI/HI 9.6.3 Rotodyanmic Pumps – Guideline for Operating Regions.

• Vibration acceptance testing of the pumps should be per ANSI/HI 9.6.4 Rotodynamic Pumps – Vibration Measurements and Allowable Values.

• Recommendations on the condition monitoring of the installed pump can be found in ANSI/HI 9.6.5 Rotodynamic Pumps – Guideline for Condition Monitoring.

• Important system components like piping connecting to the pump and free surface intakes should be designed to ANSI/HI 9.6.6 Rotodynamic Pumps for Pump Piping and ANSI/HI 9.8 Rotodynamic Pumps for Intake Design, respectively.

• Guidelines for dynamic analysis that should be conducted can be found in ANSI/HI 9.6.8 Rotodynamic Pumps – Guidelines for Condition Monitoring.

• Hydraulic performance, NPSH3, and hydrostatic acceptance testing of the pump should be per ANSI/HI 14.6 Rotodynamic Pumps for Hydraulic Performance Acceptance Tests.
