Core Technological Advantages:

Extremely High Vacuum Limit: Thanks to the strong sealing oil film formed by the lubricating oil between the screws, the ultimate vacuum level can reach below 0.5 mbar, far superior to traditional single-stage rotary vane pumps or liquid ring pumps.
Outstanding Reliability and Heat Dissipation: The oil injection circulation system not only provides lubrication but also efficiently cools the pump core, ensuring that the unit will not shut down due to overheating under 24/7 high-load operating conditions.
Built-in High-Efficiency Oil-Gas Separation: Utilizing multi-stage oil-gas separation technology, it ensures extremely low oil content in the discharged gas, effectively protecting the environment and reducing lubricating oil consumption.
Intelligent Variable Frequency Energy Saving: An optional intelligent variable frequency drive (VSD) system is available, which automatically adjusts the motor speed according to the actual gas demand, improving energy efficiency by more than 30% compared to fixed-frequency pumps.
