Mini Vacuum Pumps with Communication IO-Link, LEMAX IO

Technical Specifications

• Nozzle Diameters: 1 ;1.2 ; 1.4 mm
• Maximum Vacuum Level: 85%
• Suction Flow Rate: up to 70 Nl/min
• Integrated pressure regulator (ASR)
• Integrated vacuum regulator (ASC)
• IO-Link communication interface

 

The LEMAX IO is the new generation, IO-Link enabled mini vacuum pump developed by COVAL, integrating technologies aimed at increasing efficiency, energy saving, and productivity. It has many application areas such as the packaging, robotics, and plastics sectors.

The LEMAX IO is the first model to integrate COVAL's developed ASC (Air Saving Control) technology. It provides energy savings between 75% and 99%, depending on the product being handled

The ASC system works by optimizing energy consumption at two levels:

• Integrated vacuum regulation: Reduces air consumption and noise level
• Application analysis: Automatically adjusts the operating mode by sensing whether the part is porous or airtight

Advantages

• Easy setup and use thanks to the IO-Link communication interface
• Energy savings between 75 – 99 with ASC technology
• “All-in-one” solution: No need for external equipment
• Ultra-compact structure: Fast response and energy efficiency due to installation close to suction cups
• Long-life operation thanks to the anti-clogging flow-through silencer
• Controlled or time-set blow-off function

 

IO-Link Features

The IO-Link system provides real-time communication between the LEMAX IO vacuum pumps and higher-level protocols (EtherNet/IP, PROFINET, EtherCAT, etc.). This allows the pumps to be controlled, settings to be adjusted, and the production line to be efficiently monitored.

Advantages:

• Simple wiring, installation, and commissioning
• Instant access to diagnostic and status data
• Ease of predictive maintenance and elimination of the need for manual adjustment when replacing the pump.

 

ASC – Air Saving Control

The ASC system automatically stops compressed air consumption when the targeted vacuum level is reached. This prevents unnecessary consumption and provides significant savings in equipment operating costs.
