Lubricated Rotary Vane Vacuum Pumps and Compressors

Lubricated Rotary Vane Vacuum Pumps and Compressors feature a rotor with several vanes mounted eccentrically. Busch lubricated rotary vane vacuum pumps are:

• Lubricated with different types of lubrication
• Non-return valve prevents the pumped medium from flowing back
• Feature highly durable high performance vanes

Liquid Ring Vacuum Pumps and Compressors

Liquid ring vacuum pumps feature an eccentrically mounted impeller rotating in a housing that is partially filled with operating fluid. When impeller blades dip into the fluid, the centrifugal force of their rotation forms a liquid ring in the housing. Busch liquid ring vacuum pumps are:

• Single-stage or two-stage
• Suitable for water as the operating fluid or other liquids
• Continuous flow, partial flow, or total recirculation
• Available as liquid ring compressors

Dry Rotary Screw Vacuum Pumps

Claw Vacuum pumps feature two claw shaped rotors mounted in a cylinder that rotate in opposite directions. Claw vacuum pumps:

• High performance- High pumping speeds at inlet pressures
• Robust- High vapor & particle tolerance
• Several cooling options

Rotary Lobe Blowers

Rotary lobe blowers, or Roots blowers, have two 3-bladed lobes rotating in opposite directions. Since the lobes do not come in contact with each other, no lubrication is required. Busch manufactures both rotary lobe blowers and rotary lobe vacuum pumps.
