COVAL LEM+ and LEMAX+ Vacuum Pumps Review: Specs, Price and Applications
COVAL LEM+ and LEMAX+ are boosted, compact high-flow versions of the LEM and LEMAX mini vacuum pumps. LEM+ delivers 125 to 385 Nl/min and LEMAX+ 125 to 200 Nl/min.
LEM+ uses an Air Saving Regulator holding working pressure at 3.5 bar for about 40% average saving, suited to porous materials. LEMAX+ uses Air Saving Control to hold airtight parts without consumption, saving about 90%. Both have an HMI screen, factory presets, timed blow-off of 0 to 10 s and hold the part during power cuts.
Quick Verdict
Powerful, smart point-of-use pumps that cut air use dramatically, with a clear choice between porous and airtight duty.

Design and Operating Principle
ASR caps working pressure at 3.5 bar regardless of supply pressure, avoiding waste on porous products that need continuous flow.
ASC on LEMAX+ closes the supply once vacuum is reached on sealed parts, restarting only if vacuum falls.
Timed blow-off saves a PLC output, and a through-type silencer resists clogging.
Integration and Selection
Choose LEM+ for porous items and LEMAX+ for airtight ones. Mount near the cups and set parameters via the HMI.
