- Page 9 General overview of LEMCOM To meet manufacturers’ growing needs in terms of equipment running on field buses and Industrial Ethernet, COVAL has developed and now offers LEMCOM, a “communicating” variant of the LEMAX mini vacuum pump. LEMCOM modules are generally mounted as an “island”, based on a set of devices consisting of one master and several secondaries, but its flexible architecture (island or stand-alone module) allows each Venturi pump to be placed right up close to the application.
