Atlas Copco has launched the new GHS 402–902 VSD⁺ screw vacuum pump, marking a significant advancement in vacuum technology. As the second generation of this pump series, it introduces innovations that deliver high pumping speeds from atmospheric pressure to ultimate pressure, resulting in energy savings and faster pump-down performance.
The GHS VSD⁺ series represents a shift from traditional vacuum systems that consumed energy regardless of demand. Modern oil-sealed screw pumps are efficient systems that deliver vacuum according to demand, and this new model takes that capability to the next level.
Engineered for Performance, Designed for Sustainability
The GHS 402–902 VSD⁺ models set a new benchmark in vacuum performance, equipped with:
- A next-generation oil-injected screw element
- A highly efficient IE5 motor
- Advanced HEX@™ connectivity for Industry 4.0 integration
Ilias Alafogiannis, Product Manager, highlighted the benefits: *“With higher pumping speeds and class-leading efficiency across the entire pressure range, the GHS 402–902 VSD⁺ dramatically cuts power usage—directly improving our customers’ bottom line while supporting their sustainability goals.”*
Compact, Quiet, and Clean
The pump features a new vertically mounted, fully integrated oil-cooled drivetrain, offering clear ergonomic and operational advantages:
- 30% more compact design with a footprint of less than 1 m²
- Lower noise levels thanks to a noise-dampening canopy
- Oil-discharge levels cut by half compared to previous models, ensuring a cleaner exhaust and reduced environmental impact
Alafogiannis added: *“With a design 30% more compact and oil-discharge levels cut by half compared to previous models, combined with noise-dampening canopy, these pumps are ideal for both central vacuum systems and point-of-use applications – bringing significant improvements to the working environment of any production facility.”*
Key Advantages at a Glance
- High performance from atmospheric pressure with lower power consumption
- Compact footprint of less than 1 m²
- Heat recovery of up to 80% of pump heat as reusable hot water
- HEX@ intelligent controller enabling remote monitoring, intelligent control, and diagnostics
- Lower noise levels, better oil retention, and longer maintenance intervals
Ideal Applications
With its rapid pump-down capability and energy efficiency, the GHS 402–902 VSD⁺ is particularly suitable for:
- Food packaging
- Vacuum cooling of flowers and vegetables
- Thermoforming of plastics and white goods
The pump’s combination of performance, sustainability, and smart connectivity makes it a versatile solution for a wide range of industrial vacuum applications.
