The 2013 version of this standard for Controlled Volume Metering Pumps is an updated and expanded version of the standard issued in 2006. These reciprocating positive displacement pumps are typically used for injecting chemical additives, proportional blending of multiple components, or the metered transfer of a single liquid. They are used in applications that require highly accurate, repeatable, and adjustable rate of flow. The applications can be categorized as one of the following:Single-point injection used for pH adjustment, boiler feed treatment, or process additive injectionControlled transfer used for reactor feed, point-to-point transfer, or filling operationsMulti-stream proportioning, blending, and mixing, used for resin blending, mayonnaise production or continuous dye additionThis standard addresses specific nomenclature and definitions that are unique to metering positive displacement pumps, and provides cross-sections of designs such as:Mechanically coupled disc diaphragmSimple piston and plungerHydraulic disc with contour platesHydraulic disc with diaphragm positioning valveHydraulic tubular diaphragmHydraulic conical diaphragmControlled volume metering pumps are available with various drive configurations including:Electromagnetic driveReciprocating air driveFixed stroke-length driveMechanical lost-motion driveHydraulic lost-motion driveVariable stroke-length drive (non-lost motion)Other topics of interest in this standard include:StorageInstallation, piping, priming, alignmentLubrication requirementsOperationInspection and trouble locating
