Description

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.
