The EFR systems

The EFR system is designed to meet the demands of various industrial sectors requiring precise material dispensing.

Applications

This system is particularly well-suited for applications such as bonding, sealing, potting, and gasket application. These uses are essential in industries where high precision and reliability are critical for applying adhesives and sealants.

Industries

The EFR system is widely used across several industries. In the automotive sector, it is employed for assembly, part bonding, and sealant application. In the battery industry, it is used for applying resins and adhesives to battery cells. In the solar energy sector, it serves for sealing and encapsulating solar panels. Finally, in general industry, it enables accurate dispensing of chemicals and polymers.

Compatible materials

The EFR system supports a wide range of materials, including epoxy resins, acrylics, urethanes and polyurethanes, silicones, polysulfides, as well as thermal interface materials. This broad compatibility makes it an ideal solution for various applications requiring specific chemical properties.

The precision of the EFR system is based on a combination of advanced technologies that ensure consistent and repeatable dispensing. Its constant mix ratio is maintained by mechanically linked ‘Z’ volumetric pumps, providing optimal stability during application.
Thanks to direct motor control, the system starts and stops instantly with no flow variation. The integrated encoder ensures perfect dispensing consistency, minimizing deviations and guaranteeing optimal repeatability. Additionally, the system automatically adjusts motor speed to eliminate pulsation during pump reversal, ensuring a smooth and steady material flow. These features make the EFR system a reliable and precise solution for demanding applications.

One of the key advantages of the EFR system lies in its ease of installation and maintenance. It is compatible with various Graco supply systems, making it easy to integrate into diverse industrial environments. Maintenance needs are minimal, only the pump seals are considered wear parts reducing downtime and maintenance costs.
Thanks to its intuitive interface, the system is easy to configure and operate, offering quick adoption for operators. It can be used in both manual and robotic modes, allowing it to adapt to the specific needs of each application. This flexibility helps optimize industrial processes by ensuring precise control and maximum efficiency.

The EFR system is available with multiple configuration options to meet specific user requirements. It can be powered with either 240 V or 480 V, and available pump sizes range from 5 cc to 160 cc. Wetted components can be made of stainless steel or a stainless steel/carbon steel combination.
In terms of performance, the combined displacement of the pumps directly affects the flow rate and output pressure. For example, with a 60 cc capacity, the system can deliver up to 1,200 cc/min at a maximum pressure of 241 bar. Conversely, with a 160 cc capacity, the flow rate can reach 3,200 cc/min, with a slightly reduced pressure of 207 bar. These variations allow the system to be tailored to the specific requirements of each application.
