Description
The lubricated rotary vane 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.
The lubrification allows this pumps to intake water vapor. To avoid a condensation of the water vapor, the lubricated rotary vane vacuum pumps are equipped with the gas ballast, a system that introduces air in the compression stage and changes the vapor saturation pressure thus avoiding the condensation. Into the WR pump version the gas ballast system is improved and reinforced.
MAIN APPLICATION FIELDS
The LB 5, LB 6 and LB 8 pumps are equipped with:
- Oil check valve, integrated into their structure, which guarantees the isolation of the equipment when the pump is stopped under vacuum
- FKM gasket positioned to assure a hermetic seal and a long operating time
- Exhaust mist eliminator
- Gravity oil recovery valve
- Rotor and pump body NPO treated, to increase hardness and to withstand oxidation caused by sucking air containing high percentage of vapor
Thermal protector (1~ only)
Main application fields:
vacuum packing machines; surgical extraction for dentistry and hospitals; mixing and dosage of resin for dentistry; silk screen printing machines; automatic feeder machines for book-binding; wood presses; drilling machines for use in the construction industry
