Rotary vane vacuum pump BV 100-200-300

lubricatedsingle-stage

Oil recirculating type rotary vane vacuum pumps with nominal capacity ranging from 100 to 300 m3/h. Two different versions are available, depending on the ultimate vacuum required for the application. In the BVS version the pump reaches the ultimate vacuum of 0,5 mbar abs. In the BVM version the ultimate vacuum is of 10 mbar abs. The two versions differ only in the oil recovery system from the oil separation chamber. The pumps are designed for continuous operation within the ultimate vacuum and 400 mbar abs. The standard construction includes: flange mounted electric motor; flexible coupling between motor-shaft and pump-shaft; bearings on both sides of the pump rotor; centrifugal-type fan directly fitted onto the pump shaft extension for the cooling with ambient air; oil-air heat exchanger (for BV 200 and BV 300 only); inlet mesh filter to prevent solid parts from entering the vacuum pump; non return valve fitted in the inlet port; gas ballast valve; safety guard.
