What Are the Advantages of the VSP Series Screw Vacuum Pump?

Quality - Oil-free

One of the most significant advantages of the Screw Vacuum Pump is its oil-free operation. In contrast to traditional oil-sealed pumps, the Screw Vacuum Pump does not require oil. This eliminates the risk of oil contamination in the system or process, as well as issues such as jams caused by oil emulsification, ensuring a clean and efficient environment. In particular, this feature benefits applications in industries such as pharmaceuticals, food processing, new energy and semiconductor manufacturing, where cleanliness and efficiency are paramount.

Cost Efficient - Low Maintenance

The Screw Vacuum Pump is designed for durability and requires only minimal maintenance. Operating and maintenance costs are significantly reduced as there is no need to change oil, replace filters or dispose of contaminated oil. This not only saves time, but also reduces the total cost of ownership. The design of these vacuum pumps typically includes fewer moving parts, which further reduces the potential for wear and tear and extends the life of the pump.

Eco-Friendly - No Leakage

The unique oil-free nature of these pumps makes them an extremely environmentally friendly choice. By not relying on oil as a working medium during the production process and thus avoiding the risk of oil leakage, companies never have to worry about problems caused by leakage. In addition, there is no complicated oil disposal process, greatly reducing the impact on the environment. For companies that emphasize cleanliness and efficiency, the Screw Vacuum Pump is the ideal choice, as it maintains a high standard of working environment and guarantees efficient production.

What Is the Difference Between a Screw Vacuum Pump and an Oil Rotary Vane Vacuum Pump?

What Is the Difference Between a Screw Vacuum Pump and an Oil Rotary Vane Vacuum Pump?

The main difference between a Screw Vacuum Pump and an Oil Rotary Vane Vacuum Pump is their working mechanism and application due to the presence or absence of lubricating fluid. Oil rotary vane vacuum pumps use oil or other fluids in the pumping mechanism to seal, lubricate and cool the pumping unit, which facilitates the compression process and helps remove heat generated during operation.


In contrast, Screw Vacuum Pumps do not have any sealing or lubricating fluid in the compression chamber. This eliminates the risk of contamination by oil or other lubricants, making it ideally suited for applications that require high purity and cleanliness, while also avoiding jamming damage from oil emulsification. Furthermore, Screw Vacuum Pumps typically require no oil consumption, are less maintenance intensive (or even maintenance free), and are more environmentally friendly since they eliminate the risk of oil leaks and do not involve any handling of contaminated fluids.
