For optimum vacuum management

Coval presents the LEMAX IO series of mini vacuum pumps, which are equipped with an IO-Link communication interface and ASC technology to ensure productivity and energy savings. They are easy to install and integrate into systems, and make preventive maintenance easier thanks to the real-time availability of diagnostic data.

Coval’s new LEMAX IO series of mini vacuum pumps with IO LINK communication interface integrate all the required functions for optimized vacuum management in a compact package. Via their IO-Link communications interface, the mini vacuum pumps communicate permanently with the environment and thanks to ASC (Air Saving Control) technology, combine productivity with energy savings, adapting to a multitude of applications in packaging, robotics or plastics processing. Without needing extra peripherals, these all-in-one minis are fully compatible with Industry 4.0 automation. The IO-Link interface ensures efficient real-time communication between LEMAX IO vacuum pumps and all the higher-level protocols used for supervising the production line (Ethernet/IP, PROFINET, EtherCAT
and so on). IO-Link enables continuous diagnostics, centralized parametrization and pump control. The availability of real-time diagnostic status data makes it possible to optimize production. Installation is quicker and the cost is lower, preventive maintenance is easier and there is no manual parametrization needed when replacing the vacuum pumps.

Lightweight and compact mini pumps guarantee energy saving

ASC technology, which ensures intelligent vacuum control by stopping air consumption when the set vacuum level is reached, generates energy savings of between 75% and 99% depending on the application. In addition, ASC analyses the application and adapts to either impermeable or porous parts to optimize operation and energy consumption. Compact in size, the LEMAX IO pumps have all the principal functions integrated in a single module: pressure regulation, solenoid valves, anti-clogging open silencer, electronic vacuum switch, M8 connector (direct plug & play connection) and adjustable blowing. Their reduced size and weight (130 g) allow the suction cups to be positioned at minimum distance to achieve the shortest possible grip time without load loss. The LEMAX IO can be adjusted to the needs of integrators and users. They are available in three nozzle diameters (1, 1.2, 1.4 mm) allowing a suction flow rate from 29 to 70 Nl/min (maximum vacuum 85%). They are optionally equipped with a normally closed (NC) or normally open (NO) solenoid valve. This variant is recommended for applications where gripping the workpiece must be guaranteed in case of an unexpected power failure, or even if leakage occurs (positive safety). Several LEMAX IOs can be combined in an island with a single pressure supply.
