The Hydraulic Institute (HI, www.pumps.org) released “ANSI/HI Pump Standards Version 2.1” on CD-ROM, offering a digital compilation of its complete set of 28 ANSI/HI Standards. Five of the standards have been extensively updated since the release of Version 2.0 in 2005. In addition, the CD-ROM includes the first edition of the Controlled Volume Metering Pumps for Nomenclature, Definitions Application and Operation (ANSI/HI 7.1-7.5).

Development of the Controlled Volume Metering Pumps Standard was a collaborative effort between American Lewa, Inc., Grundfos Pump Corporation, Iwaki America Inc., McFarland-Tritan, LLC, Milton Roy Americas, Siemens US Filter/Wallace & Tiernan and the Hydraulic Institute.

This new standard is for reciprocating positive displacement pumps that are typically used for the injection of chemical additives, proportional blending of multiple components or metered transfer of a single liquid. These types of metering pumps are used in applications that require highly accurate, repeatable and adjustable flowrate. Controlled-volume metering (CVM) pumps are characterized by their ability to meet specific performance requirements regarding steady state accuracy, repeatability and linearity. Topics in this standard include the types and nomenclature pertinent to CVM pumps; an explanation of the definitions used in describing the performance and characteristics of CVM pumps; a discussion of how CVM pumps are selected and where they are applied; and a section on the proper installation, operation, and maintenance of CVM pumps that will ensure trouble-free operation.

Updated Standards in Version 2.1 include:

  • ANSI/HI 1.3 Rotodynamic (Centrifugal) Design and Application – 2009
  • ANSI/HI 2.1 – 2.2 Rotodynamic (Vertical) Nomenclature – 2008
  • ANSI/HI 2.3 Rotodynamic (Vertical) Design and Application – 2008
  • ANSI/HI 2.4 Rotodynamic (Vertical) Installation, Operation, & Maintenance – 2008
  • ANSI/HI 3.1-3.5 Rotary Pump Standard – 2008

The complete set of ANSI/HI Pump Standards CD-ROM Version 2.1 (HI Order Code CD-ROM 2.1) is available to purchase for $850.00. For more info, visit www.pumps.org.
