Standards updates introduced for pumps

The Hydraulic Institute (HI) has updated the 2000 edition of the ANSI/HI standard on sealless centrifugal pumps and published ANSI/HI 5.1-5.6–2010 Sealless Rotodynamic Pumps for Nomenclature, Definitions, Application, Operation and Test. The revised standard covers sealless rotodynamic pumps driven by canned motors or through magnetic couplings with conventional motors.   

John Owen, IMO Pump (Colfax Corp.), and Alan Wild, Moyno, Inc., led the committee that developed the standard, which also included representatives from Flowserve Pump Division, Leistritz Corporation, Intelliquip LLC, Milton Roy Americas, Roper Pump Company, Siemens Water Technologies, and Weir Floway, Inc.
