ANSI/HI 7.1-7.5-Controlled-Volume Metering Pumps for Nomenclature, Definition, Application and Operation

Overview:

This standard defines the nomenclature, design and application considerations in choosing the right pump for a specific industry use as well as pump operating and maintenance procedures.

Controlled-volume metering pumps are typically used for injecting chemical additives, proportional blending of multiple components, or the metered transfer of a single liquid in application requiring high accuracy, repeatability and adjustable rate of flow.  Markets include: water treatment plants, chemical processing, pharmaceuticals, semiconductors. Pump end users, specifying engineers, and consultants serving these industries will benefit from using this standard to select the right controlled-volume metering pumps for an application to get the best performance.

What’s New:

This standard supersedes the ANSI/HI 7.1-7.5-2017 edition. Updates in the new edition include:

  • New troubleshooting table
  • Updated definitions to align with ANSI/HI 7.8 Controlled-Volume Metering Pumps Piping Guideline and ANSI/HI 10.1-10.5 Air Operated Pumps
  • Updated terminology of NPIPA and NPSHR
