CMSMulti-stage Vacuum Pumps With its multi-stage ejectors, CMS series, COVAL proposes an adapted response to all applications which need high suction flow; like emptying of high volume tanks or handling of porous objects. Thanks to their characteristics, the CMS multi-stage vacuum generators are perfectly suited to feed vacuum grippers at a distance. ■ Optional control valve for vacuum and release cycles ■ M12 Connector Performance Curves Control Versions Option R NC vacuum control, without blow-CMS90X_ _RV_ ■ 1 control signal. ■ NC vacuum control valve.
