MINI-VACUUM PUMP WITH FIELDBUS COMMUNICATION, LEMCOM SERIES

Product catalog summary

Introduction: The document introduces the LEMCOM series, a line of mini vacuum pumps designed for integration into industrial networks, featuring communication via industrial fieldbus and supporting EtherNet/IP and PROFINET protocols.

Key Features:

Integrated Functions: The pumps include a pressure regulator, vacuum solenoid valve, optimized venturi, silencer, non-return valve, vacuum sensor, integrated electronics, blow-off solenoid valve, and flow regulator.
Energy Efficiency: Utilizing ASR (Air Saving Regulator) and ASC (Air Saving Control) technologies, the pumps achieve up to 90% energy savings for airtight products and 40% for porous products.
Compact Design: These are the most compact vacuum pumps available, facilitating easy installation and quick response times.
Safety and Reliability: The pumps maintain product grip during power failures and are dust-resistant.
Communication and Control: They support remote monitoring, configuration, and diagnostics through a web server and dedicated software.

Applications: The pumps are suitable for handling various materials, including cardboard, food, wood, paper, plastic, metal, glass, composites, and concrete/stone.

Energy-Saving Technologies:

ASR: Regulates pressure to 3.5 bar, optimizing venturi operation and reducing unnecessary air consumption.
ASC: Automatically adjusts to maintain vacuum levels, significantly reducing air consumption during operations.

Configuration and Diagnostics: The LEMCOM series offers configurable settings for vacuum regulation, automatic blow-off, and network parameters, providing diagnostic data such as cycle counters, power supply voltage, and firmware version.

Modular Design: The system supports up to 16 modules, with a master module managing communication and control. Modules can be configured in stand-alone, island, or mixed configurations, providing flexibility and proximity to applications.

Specifications:

Maximum vacuum levels: 85% for airtight products, 60% for porous products.
Nozzle diameters affect vacuum flow rate and energy consumption.
Operating pressure: 4.5 to 7 bar.
Integrated non-clogging silencer and noise level approximately 68 dBA.
Electric protection grade: IP65.

Configurations:

Stand-alone and island configurations with master and secondary modules.
Options for NC (Normally Closed) and NO (Normally Open) vacuum control valves.
Exhaust manifold option for external exhaust management.

Communication and Diagnostics:

EtherNet/IP and PROFINET communication with embedded web server.
Continuous monitoring of leakage levels and automatic adjustments.
Diagnostic tools include LEMCOM Manager software and embedded web server.

Mounting and Connections:

DIN rail and front mounting options available.
Electrical connections via M8 and RJ45 connectors.
Accessories include various lengths of Ethernet and power supply cables.
