Dosing systems

DOPAG single component dosing systems are available in several formats, depending on a number of factors, such as the required volume of the shot to be dosed and the viscosity of the media.

All dosing systems require either a drum or transfer pump to feed the media from the original container, under pressure to the dosing station, where the media is metered by either a metering valve or by means of an electronic volume counter system.

DOPAG have a comprehensive range of metering valves for use with dosing systems that are used to apply accurately metered shots of media in many different processes and in a variety of industries, from the application of precision shots of oil or grease onto automotive components to dosing silicone into cartridges.

DOPAG metering valves are available in three different designs, all of which work on a volumetric principle. These metering valves can handle all types of media from low to high viscosity, such as adhesives, sealants, greases, oils, pastes and silicones. All DOPAG metering valves are pneumatically actuated and cover metered shot volumes of between 0.001ml and 100ml.

For dosing systems that require volumes above 100ml, an option is to employ the electronic volume counter system, which has unlimited volumetric metering capacity and is particularly suitable for such applications as engine or gearbox filling. Its integral metering feedback verification system makes it an ideal solution for use with automated assembly applications.
