Lubricated vacuum pumps are used when the intake flow may contain moisture, or when a better final pressure is required.
These pumps may run continuously within certain pressure ranges, or connected to containers to be emptied, whose volume is sized appropriately for the pump flow rate.
Long-term use at atmospheric pressure is not recommended.
When the amount of vapour intake is considerable, we recommend using the WR versions.
The main areas of use include: vacuum packaging, thermoforming machines, glassor marble-working machines, medical equipment, food-grade pastas or clay extruders.
