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
Compact design, low noise level, simple oil check and refill and ease of maintenance, are the main features of LC 20 and LC 25 lubricated rotary vane vacuum pumps. The damping and recovery system, equipped with a by-pass, together with the new float type oil recovery valve, ensures the absence of oil vapors at the outlet. Moreover, a sealing device prevents the oil from being sucked back should the pump stop under vacuum. The LC 20 is suitable for continuous operation within a pressure range from 400 to 2 mbar (Abs.) and LC 25 from 400 to 0,5 mbar (Abs.).
The LC 20 and LC 25 pumps are equipped with:
- Oil check valve
- Exhaust mist eliminator
- Automatic floating oil recovery valve
- Adjustable inlet fitting
- Continuously working gas ballast
- Shock mounts
- Thermal protector (1~ only)
- Pack of BV32 oil (LC 20)
- Pack of BV68 oil (LC 25)
Main application fields:
vacuum packaging machines; sack filling machines; vacuum precious metal casting machines; dental field; graphic and paper industry; CNC marble and glass machines; vacuum lifting machines; garage equipment.
