Vacuum handling in industry responds to very diverse contexts: materials and weight of the parts to be handled, integration on machines and robots, high speeds.

COVAL’s Heavy Duty vacuum pumps, GVMAX HD series, combine robustness, power, modularity, and communication to adapt to multiple applications.

They are, thanks to the IO-Link technology, fully connected to the Industry of the Future.

IO-Link and NFC, simplified communication
The IO-Link communication interface of the Coval GVMAX HD vacuum pumps allows a fast and economic installation, continuous diagnostics, centralized parameterization, and efficient communication with higher-level protocols (EtherNet/IP, PROFINET, EtherCAT…).

In addition, all parameterization and diagnostic functions are available and can be modified on mobile devices (Android and IOS) thanks to the NFC technology that equips the GVMAX HD vacuum pumps and the dedicated application COVAL Vacuum Manager. This binomial allows to copy parameters from one pump to another very easily and offers the possibility to save up to 5 different parameter configurations.

The operator has been placed at the center of the product ergonomics with a Human Machine Interface (HMI) that facilitates the reading of operating, diagnostic, and maintenance information and allows quick parameterization. The 1.54” color LCD display is intuitive, with explicit messages in 5 languages. The pump status is highly visible thanks to a 3-color status light.

Finally, with the GVMAX HD vacuum pumps, the user can benefit from technical assistance thanks to the data sent through the application to the COVAL experts.

This new GVMAX HD vacuum pump, designed to permanently communicate with its environment, thus takes its full place in Industry 4.0.

Performance, robustness, and energy savings
Equipped with a single-stage venturi, the GVMAX HD vacuum pump provides powerful suction rates and reduced emptying times for gripping, transferring, or clamping parts of various sizes and weights.
For example, max. vacuum: 85%, suction rate up to 230 Nl/ min and 0.4 s to empty a volume of 1 liter at 75% vacuum.

Each component has been designed and tested in real-life situations to meet the most difficult environments. Thus, the pumps are IP65 and guaranteed for more than 50 million cycles.

The performance of the vacuum pumps is combined with reduced energy consumption.
The ASC (Air Saving Control) technology, which provides intelligent vacuum regulation by stopping air consumption when the set vacuum level is reached, offers up to 90% energy savings.

Ease of use
The GVMAX HD is designed to allow quick and easy maintenance interventions while minimizing production constraints. The patented Smart Swap quick-change system, a Coval novelty, allows changing pumps without tools and under pressure.

In addition, the modular design of the GVMAX HD makes it possible to target interventions on each pump element, reducing both costs and intervention time.

To adjust to the installation configuration and available space, the choice is given between a stand-alone assembly of each pump or an island assembly (up to 4 pumps) with an internal pressure common.

The GVMAX HD Heavy Duty vacuum pumps are the result of more than 30 years of collaboration between COVAL and industrialists from all sectors.

They fully meet their requirements: versatility, robustness, performance, and communication.
