Bellows-sealed Oil-free Dry Scroll Vacuum Pump
VPSL series bellows sealed dry scroll vacuum pump is a completely oil free and clean vacuum pump, with pumping speed of 12m3/h(7CFM), 16m3/h(9CFM), and 36m3/h(20CFM).
VPSL Series Bellows-Sealed Oil-Free Dry Scroll Vacuum Pump
Clean. Quiet. Intelligent. Reliable.
The VPSL Series Bellows-Sealed Dry Scroll Vacuum Pump is a next-generation, completely oil-free vacuum solution designed for applications where cleanliness, low noise, and reliability matter most. Available pumping speeds of 12 m³/h (7 CFM), 16 m³/h (9 CFM), and 36 m³/h (20 CFM) make the VPSL series ideal for laboratories, analytical instruments, leak detection systems, and precision processes.
100% Oil-Free, 100% Clean
The VPSL pump operates without any lubricating oil, eliminating oil contamination and oil vapor backstreaming entirely. This ensures a clean, stable vacuum environment and reduces maintenance costs by removing the need for oil changes.
Advanced Bellows-Sealed Technology
At the heart of the VPSL series is an advanced bellows-sealed isolation structure that fully separates the compression chamber from the bearing system. This innovative design enhances cleanliness, extends service life, and significantly improves operational reliability—making it an excellent choice for contamination-sensitive industries such as semiconductors, pharmaceuticals, and analytical laboratories.
Ultra-Quiet and Low Vibration
Designed for comfort-sensitive environments, the VPSL dry scroll vacuum pump delivers exceptionally quiet operation at ≤ 53 dB with minimal vibration (< 3 mm/s). It integrates seamlessly into laboratories, cleanrooms, and indoor workspaces without disrupting daily operations.
Intelligent Control, Smarter Operation
The VPSL series is equipped with an independent intelligent controller that automatically adjusts pump speed based on process demand. Functions such as variable speed control, current limiting, and voltage stabilization ensure optimized performance, improved energy efficiency, and longer pump life.
High Performance with Lower Energy Consumption
Using proven scroll compression technology, the VPSL pump delivers fast evacuation and stable vacuum performance while consuming less energy. The result is higher productivity, shorter process times, and reduced operating costs.
Compact Design, Easy Integration
With its compact footprint (438 × 268 × 300 mm), the VPSL oil-free dry scroll vacuum pump is easy to install in space-limited systems and fits seamlessly into both new and existing equipment layouts.
Built for Reliability and Easy Maintenance
Manufactured with high-quality components and precision engineering, the VPSL series offers long service life and consistent performance. Its user-friendly design allows for quick maintenance and reduced downtime, ensuring maximum uptime for your operations.
