HI 7.1-7.5 – American National Standard for Controlled-volume Metering Pumps for Nomenclature, Definitions, Application, and Operation

HI 7.1-7.5-2017 offers a basic educational overview on controlled-volume metering pumps, 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 available with various drive configurations including:

• Electromagnetic drive
• Reciprocating air drive
• Fixed stoke-length drive
• Mechanical lost-motion drive
• Hydraulic lost-motion drive
• Variable stroke-length drive (non-lost-motion)

What You Will Learn/Overall Benefits:

• Gain a fundamental understanding of controlled- volume metering pumps to properly classify and describe different pump types
• Learn what terms apply to different pump parts to better communicate with manufacturers and other pump people using standardized terminology
• Understand how to identify pump parts for troubleshooting in the field
• Identify the difference between pump designs and characteristics to choose the best one for a specific application
• Learn how to operate pumps

Applicable Markets: 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.
