This version of the standard has been superseded. PDF copies still remain available for purchase.
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.
