Mini Vacuum Pump

Coval Vacuum Technology (Raleigh, NC) offers the LEMAX mini vacuum pump that features Air Saving Control (ASC) technology in which air is only consumed to create the vacuum and enable gripping and moving the piece. Once the regulated vacuum level has been reached, a valve closes, enabling the piece to be held without any consumption of energy. If the vacuum level drops, an air intake is generated until it returns to the initial value. The ASC analyzes the application and adapts to airtight or porous pieces in order to optimize energy use and consumption. All main functions are integrated in a single module: pressure control, pilot solenoid valves, non-clogging through-type silencer, electronic vacuum switch, M8 connector (plug-and-play direct connection), and adjustable blow-off. It can be provided with a normally closed (NC) or normally open (NO) solenoid valve.
