NOTE
Technical term. In this instruction manual, we consider that the term ‘machine’ refers to the ‘vacuum booster’.
 Illustrations In this instruction manual the illustrations may differ from the machine appearance.
2.1
Operating Principle
The machine works on the Booster blower principle. The two oil housings (on each side) allow the lubrication of the gears, bearings and in certain versions the oil lubricated mechanical seals. A bypass valve (BPV) limits automatically the differential pressure between inlet and outlet.
2.2
Intended Use
WARNING
In case of foreseeable misuse outside the intended use of the machine. Risk of injuries! Risk of damages to the machine! Risk of damages to the environment! ●  Make sure to follow all instructions described in this manual. The machine is intended for the suction of air and other dry, non-aggressive, non-toxic and non- explosive gases. Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment. The machine is used in combination with a backing pump in vacuum system. The machine is suitable for continuous operation. Permitted environmental conditions, see Technical Data [→ 29]. Chemical compatibility of the process gases with the machine component materials. Risk of corrosion inside the compression chamber which can reduce performance and its lifetime! ● Check if the process gases are compatible with those following materials: - Cast iron - Steel - Aluminium - Fluoroelastomer (FKM/FPM) ● In doubt, please contact your Busch representative.
Transport
Suspended load. Risk of severe injury! ● Do not walk, stand or work under suspended loads. Lifting the machine using the motor eye bolt. Risk of severe injury! ● Do not lift the machine using the eye bolt fitted to the motor. Only lift the machine as shown.
NOTICE
In case the machine is already filled with oil. Tilting a machine that is already filled with oil can cause large quantities of oil to ingress into the cylinder. ● Drain the oil prior to every transport or always horizontally transport the machine. ● To find out the weight of the machine, refer to the chapter Technical Data [→ 29] or the nameplate (NP). ● Use appropriate slings. ● Check the machine for transport damage. If the machine is secured to a base plate: ● Remove the machine from the base plate.
