BUSCH HUCKEPACK two-stage oil vacuum pumps have proven themselves in the toughest applications and have demonstrated their durability and reliable operation over decades. All four sizes have a two-stage design. Fresh oil lubrication enables trouble-free pumping of corrosive gases or vapors.
Oil vacuum pumps maintain a consistently high level of vacuum during continuous operation, guaranteed by circulating oil lubrication, excellently matched materials, and extremely high manufacturing precision that ensures clean, oil-free exhaust thanks to a sophisticated oil extraction system with integrated oil return. When the gas ballast valve operates, it is possible to extract large amounts of vapor. A non-return valve in the suction inlet prevents air from re-entering the vacuum chamber when the pump is turned off.
