glueLine Solutions for the application of 1K adhesives and sealants

Metering 1K materials Industrial application of adhesives and sealants Bonding and sealing LED lights DOPAG single-component systems convey media such as adhesives, sealants, greases and oils with high precision from their original containers to the point of application, where the material is applied to the workpiece either in shot form or continuously in bead form. The systems are fitted with gear, piston or progressive cavity pump, depending on requirements. Provided the medium is fluid or has low viscosity, single-component materials can be processed by means of a material pressure tank. For...

Products for every part of the process

DOPAG · GLUELINE GLUELINE · 07 Material feeding To ensure proper metering, it is important that adhesives are conveyed efficiently and without air any pockets (air bubbles). Only through continuous, reliable material supply can optimal metering results be ensured. Depending on the material properties, process and container size, different supply systems may be chosen. DOPAG’s product range offers a comprehensive range of solutions for this. This includes drum and barrel pumps as well as pressure tanks. DOPAG uses established technology in all of its systems – gear, piston or progressive cavity...

DOPAG developed the drum pumps in the glueLine product range especially for feeding adhesives and sealants. The reliable design combined with the high level of user-friendliness allow for worry-free everyday production operations. With the glueLine, DOPAG offers drum pumps for processing medium to high-viscosity materials. In addition to lubricants, they feed adhesives, sealants, polyurethanes and silicones with viscosities of up to 5.0 million mPas directly and precisely from the original container. Thanks to its modular design and wide range of variants, the pump can be tailored precisely to...

Drum change support Drum pallet Drums can be prepared and centered in advance in the warehouse, saving time when changing drums. Simple and efficient drum change Various drum change support options are optionally available to protect the operator from excessive loads. The drum roll-in mechanism allows containers to get more easily onto the base plate. With the drum roller conveyor the container stands on rollers and can be centred more conveniently under the follower plate. With the third and final expansion stage, lifting is no longer necessary completely. The drum is changed using a mobile...

Tandem pumps Transfer pumps For continuous material feeding For direct transfer from original containers Many applications require an uninterrupted material feed maintained at all times. For such cases, all DOPAG pump models are available as a tandem version. Tandem pumps feature an automatic mechanism that switches between the pumps whenever material level is low, so that container change can proceed without interrup- Depending on the application type, it may be useful to be able to supply material directly from the original containers using a transfer pump. DOPAG transfer pumps are double-acting...

Refill units Pressure tanks For automated refilling Flowable materials delivered effortlessly To ensure uninterrupted production, automated refilling of the material pressure tanks is essential. DOPAG offers various compact refill units for this purpose. The fill level probe in the material pressure tanks enables refilling to be started automatically from a defined material quantity. This ensures that there is always sufficient conditioned material available for production and machine downtime is avoided. Media with viscosities ranging from highly fluid to approx. 80,000 mPas can be conveyed...

Material pressure regulators abrasive media (ball/seat design made from hard metal), such as epoxy resin, polyurethane and various other materials. The spring chamber is sealed by means of a diaphragm. Pulsation-free dispensing with the right pressure Material pressure regulators reduce the pressure of the material being conveyed down to the necessary working pressure, A material pressure regulator with a diaphragm is available for abrasive or reactive materials. Material pressure regulators of this type are ideally used for the processing of reactive, moisture-sensitive, Technical specifications...

Metering and dispensing As precise as you need Metering and dispensing valves from DOPAG meet all the criteria required for optimal metering results – high precision, excellent reproducibility and high quality standards. DOPAG offers different valve types with two operating principles. Needle metering valves meter volumetrically (dot application). In each metering cycle, the contents of the metering chamber are discharged, triggered by a signal. The benefits of this are high repeatability and flexibility thanks to adjustable volumes. In the case of dispensing valves, however, the metering volume...

Gear metering pumps Gear metering pumps from DOPAG offer all the features that are required in industry today. They meter a wide range of materials, including adhesives, sealants and lubricants, continuously and with consistently high precision. They are also designed in such a way that they are extremely robust, have a high level of efficiency and are practically pulsation-free. ■ Versatile use thanks to different pump sizes, clearance classes and seal systems. ■ High-quality, hardened steel ensures operation even under difficult conditions. ■ Special coating for protection against excessive...

DOPAG • GLUELINE Piston metering systems Piston metering units are used for processing 1K media, especially when short cycle times are required. All that is required is appropriate material supply and a metering calculator. The material is discharged in shot form at a freely configurable discharge rate or without interruption using a double piston system, e.g. in bead form. Different sizes are available depending on the requirements of the application. Combing two piston metering units together also enables 2K applications with this system. It is powered by a servo motor, with a spindle converting...
