LB 6 / LB 8 / LC 12

The limited dimensions and the low final pressure (Abs.) attainable are the main features of LB 6, LB 8 and LC 12 lubricated rotary vane vacuum pumps. An effective damping and recovery system in-built in the tank prevents any oil vapors at the exhaust. Moreover, a special sealing device prevents suck-back, should pump be stopped under vacuum. The intake can also be adjusted by the user, thanks to a special fitting. The LB 6, LB 8 and LC 12 pumps are suitable for evacuation of small closed vessels and, only LC 12, for a continuous operation within a pressure range from 400 to 2 mbar (Abs).

Nominal capacity: 4.1 – 8.2 CFM

The LB 6, LB 8 and LC 12 pumps are equipped with:

  • Oil check valve
  • Exhaust mist eliminator
  • Gravity oil recovery valve (LB 6 / LB 8)
  • Floating oil recovery valve (LC 12)
  • Gas ballast continuously working
  • Thermal protector (1~ only)
  • Pack of BV32 oil

Main application fields: filling and sealing machines, food packing and food processing, and production of PET containers.
