References geared towards anyone involved in pumps
In what has been a banner year for new ANSI/HI Standard introductions, the Hydraulic Institute (HI) has announced the release of three new publications: “Rotodynamic (Centrifugal) Pumps for Nomenclature and Definitions,” “Rotodynamic (Centrifugal and Vertical) Pumps – Guideline for Condition Monitoring” and “Pump Piping for Rotodynamic Pumps.”
“Rotodynamic (Centrifugal) Pumps for Nomenclature and Definitions” covers overhead impeller, separately coupled pumps; between bearing, separately coupled, single stage pumps; between bearing, separately coupled multistage pumps; regenerative turbine pumps; and special effects pumps. Also included are descriptions of types, nomenclature and definitions.
“Rotodynamic (Centrifugal and Vertical) Pumps – Guideline for Condition Monitoring” is designed to be used as a tool in implementing process safety management and also for general pump availability improvement programs for centrifugal and vertical pumps, including both sealed and sealless pump designs. While the document does not require that monitoring be done, this new reference tool does provide information relevant to making such decisions, and offers suggestions for carrying out the monitoring process.
“This standard has been thoroughly updated to include the latest instrumentation available to ensure long, uninterrupted pump operation,” said Gregg Romanyshyn, technical director for HI. “Valuable new information has been added, including details on how regular equipment monitoring can minimize the number of shutdowns.”
“The standard has been reviewed and enhanced to provide even more guidance to those who use pump condition monitoring in their process safety management system,” said Ed Allis, special projects manager, engineering, Peerless Pump Co., and chairman of the HI Condition Monitoring Committee.
Hydraulic Institute is also introducing “Pump Piping for Rotodynamic Pumps.” Initially published a number of years ago as a two-page section within “Pump Intake Design,” the subject matter was deemed broad enough, and popular enough, to warrant a stand-alone publication. The content covers the effects and interactions of inlet (suction) and outlet (discharge) piping on rotodynamic pump performance; solutions for avoiding problematic situations resulting from poorly designed suction piping, poorly supported piping, unrestrained or inadequately restrained expansion joints and uncompensated thermal expansion of the piping system; and more.
