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 appropriately sized for the pump flow rate.
Long-term use at atmospheric pressure is not recommended.
We recommend using the WR versions whenever the amount of intake vapour is considerable.
The main application fields include: vacuum sealed packaging, thermoforming machines, glass or marble working machines, medical equipment, food-grade pastes or clay extruders.
