Dry
Basai Multi Claw Vacuum Pump
A multi-claw vacuum pump is a type of dry, oil-free positive-displacement vacuum pump that uses multiple claw-shaped rotor stages arranged on a common shaft to generate vacuum.

Key features
Why the Multi Claw Vacuum Pump
- Dry & oil-free operation – No oil is required in the pumping chamber, preventing oil contamination.
- Non-contacting claw rotors – Rotors operate with precise clearances without touching each other or the housing.
- Multi-stage compression – Multiple claw stages provide higher compression and deeper vacuum than a basic single-stage arrangement.
- Low maintenance – No pump oil to replace and minimal wear of the pumping elements.
- High reliability – Suitable for continuous industrial operation.
- Energy efficient – Efficient positive-displacement pumping, particularly in appropriate operating ranges.
- Low operating temperature – Designed to minimize heat generation compared with some conventional technologies.
- Clean vacuum – Suitable for applications where oil backstreaming or contamination is undesirable.
- Compact construction – Multiple stages can be integrated into a relatively compact pump package.
- Wide industrial application range – Useful in packaging, conveying, food processing, pharmaceuticals, plastics, chemical processes, and vacuum handling.
