MINK SERIES

Claw vacuum pumps

MINK claw vacuum pumps were developed by BUSCH for industrial applications in which constant vacuum, high pumping speed and completely oil-free compression are essential. MINK pumps are available as single-stage or two-stage vacuum pumps for a deeper vacuum. The vacuum is generated by two non-contacting rotors in a dry and oil-free pump chamber.

MINK SERIES ADVANTAGES

• Dry pump chamber
• Low noise level
• Simple, modular design
• Suitable for variable speed applications
• Suitable for dusty environments
• Contact-free design
• Air cooling

COBRA NC SERIES

Screw vacuum pumps

The dry COBRA NC screw vacuum pumps work highly efficiently in many industrial processes in which gases and vapours are conveyed reliably and without contamination. High liquid and particle tolerance is made possible by the asymmetrical screw profile and the free gas outlet. Best corrosion resistance thanks to even temperature distribution. The excellent efficiency reduces thermal load and increases service life.

COBRA series advantages

• Advanced screw design
• Efficient
• Robust
• High performance
• Flexible
• Reliable
• Economical

PANDA / PUMA SERIES

Roots vacuum pumps

Panda and Puma vacuum boosters are dry vacuum generators that can be used in combination with a backing pump in all rough and medium vacuum processes. In such a vacuum system, as boosters they enormously increase the performance data of the backing pump. Thanks to the large number of available sizes and versions, the pumping speeds and ultimate pressures of vacuum systems can be matched exactly to the process conditions with Panda or Puma vacuum boosters.

SERIES ADVANTAGES

• Oil-free operation
• Wide range of available sizes
• Higher pumping speed
• Economical
• Safe operation

SECO SD SERIES

Rotary vane compressors, oil-free

Seco SV dry-running rotary vane compressors are compact, reliable and extremely powerful. Lubricant-free compressed air generation ensures efficient and pulsation-free provision of compressed air up to 1 bar (g) for a wide variety of industrial applications. SECO rotary vane compressors are characterised by oil-free compression, high availability and operational reliability.

SERIES ADVANTAGES

• Reliable
• Dry-running
• Simple service and maintenance
• Economical operation and maintenance
• Compact design – direct drive

SAMOS SERIES

Side channel compressors

Samos side channel blowers can be used in all areas where pulsation-free conveying of the medium in the vacuum and pressure range is required. Installation in horizontal and vertical position is possible. Robust design thanks to die-cast aluminium parts. Samos side channel blowers are absolutely maintenance-free thanks to the permanently greased bearings, the air-cooled drive motor and the contact-free rotating impeller.

SERIES ADVANTAGES

• Multiple installation options
• Maintenance-free
• Die-cast aluminium construction
• Environmentally friendly
• No operating fluid required

MINK SERIES

Claw compressors

Mink claw compressors were developed specifically for the reliable compression of air and other gases. Mink claw technology guarantees the efficient and constant provision of overpressure up to 2 bar(g) for many applications in industry. Thanks to modern claw technology, the gas is compressed without contact and completely oil-free. Because of this dry compression, the gas is not contaminated and can be used further without filtration or cleaning.

SERIES ADVANTAGES

• economical thanks to high efficiency
• compact design thanks to simple construction
• only minimal maintenance work required
• absolutely dry compression principle
• air-cooled, no cooling water required
• speed-controllable (option)
• long service life

CAT / DINGO SERIES

Rotary lobe compressors

The three-lobe Cat and Dingo rotary lobe blowers compress oil-free and contact-free. No lubrication necessary, therefore no contamination of the conveyed medium by lubricants. Thanks to robust design and high precision in manufacturing. Labyrinth seals between cylinder and gearbox housing. Thanks to the modular principle and standard motor. Maintenance is limited to oil changes in the gearbox and greasing of the bearings. Thanks to high volumetric and mechanical efficiency.

SERIES ADVANTAGES

• Reliable
• Economical
• Application-oriented
• Easy to maintain
• Vacuum and pressure operation

SECO PRINT DC SERIES

Rotary vane pressure-vacuum pumps, oil-free

Seco DC combined rotary vane vacuum pumps/compressors were developed specifically for handling paper in printing presses and in print finishing. They reliably supply vacuum to hold, move or transport paper. The blast air generated at the same time helps to separate individual sheets from the paper stack. Seco DC are characterised by absolutely oil-free vacuum and blast air generation, high availability and operational reliability.
