Metering Components + Pumps

Metering components and pumps by DOPAG are used in various industries for applying low to high-viscosity media. They guarantee high precision and accurate repeatability regarding the discharged quantities.

The metering system requires either the use of a drum or a vessel pump for pumping the material out of the original containers to the metering station under pressure. There, the material is metered either via a metering valve or via an electrical volumetric meter.

DOPAG metering valves are available in different versions which are all based on the volumetric metering principle. These metering valves are capable of processing low to high-viscosity media such as adhesives, sealants, greases, oils, pastes, and silicones.

The electronic volumetric metering system, which features an unlimited volumetric metering capacity, is perfectly suited for metering systems with a discharge volume of more than 100 ml. It is also suited for machine or gearbox filling. The integrated metering quantity feedback is an ideal solution for automated applications.
