Rotary vane vacuum pump BV 26-40

lubricatedsingle-stage

Oil recirculating type rotary vane vacuum pumps with nominal capacity ranging from 26 to 40 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: • flexible coupling between motor-shaft and pump-shaft; • flange mounted electric motor; • centrifugal-type fan directly fitted onto the pump shaft extension for the cooling with ambient air; • hub between pump body and electric motor; the hub also acts as safety guard; • bearings on both sides of the pump rotor; • inlet mesh filter to prevent solid parts from entering the vacuum pump; • non return valve fitted in the inlet port; • gas ballast valve; • antivibration pads.
