- FAQ
A screw vacuum pump utilizes a pair of screws rotating synchronously at high speed in opposite directions within the pump casing to achieve suction and exhaust functions. The two screws are precisely calibrated through dynamic balancing and maintain a specific clearance between each other. Therefore, the pump operates without friction between components, ensuring stable running, low noise levels, and no requirement for lubricating oil in the working chamber.
Oil-Free Cleanliness & Dual Advantages of Cost Efficiency & Safety
Oil-free operation chamber ensures zero-pollution delivery of process gases. High gas recovery rate and easy tail gas treatment significantly reduce operational costs and safety risks.
High-Efficiency Cooling & Lower Energy Consumption
Equipped with jacket cooling technology, the equipment maintains stable operation with only a small amount of circulating cooling water, achieving high cooling efficiency, water conservation and energy saving.
Superior Working Condition Adaptability & Wide Application Scope
Capable of efficiently pumping various complex gases including condensable, corrosive, flammable, explosive, crystallizable and solidifiable types, and easily copes with harsh working environments.
Stable & Reliable Performance & High Operating Efficiency
Adopts multi-stage helical rotors and eliminates the intermediate partition structure, removing middle-stage suction and exhaust processes. The working process is simple, continuous, and greatly improves operational efficiency and stability.
Low Maintenance & Long Service Life of the Whole Unit
The contact-free, wear-free rotors feature a simplified structure with fewer components, facilitating convenient post-maintenance. The equipment also has a low failure rate, effectively extending the service life of the whole unit.
Strong Flexible Compatibility & Versatile Combination Applications
Boasts a wide inlet pressure adaptability range (stable operation from 1 Pa to atmospheric pressure). It can be combined with Roots pumps, molecular pumps and other equipment, and delivers excellent pumping efficiency when used as a forepump.
