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
LB 5WR lubricated rotary vane vacuum pump has the same features as LB 5, but it is equipped with a device which splits oil and water condensate, being the latter expelled when the pump is stopped. As a result of this construction it is possible to use the LB 5WR in applications where very high concentrations of water vapour might be present, and where standard pumps could not be used.
The LB 5WR is suitable for continuous operation within a pressure range from 400 to 10 mbar (Abs.).
Nominal capacity: 5 – 6 m3/h 3.5 CFM
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
