Oil lubricated Rotary Vane Vacuum Pump

Yuzhen adopts a mature rotary vane structure design. The rotor rotates within the pump chamber, and high-quality vacuum oil is used for sealing, lubrication, and cooling, achieving continuous and stable vacuum output.

The advantages of this structure are straightforward:

Fast startup

Short vacuum build-up time

Strong adaptability to working conditions

Stable operation even during long periods of use

Can the vacuum remain consistently stable?

When the Yuzhen Oil lubricated Rotary Vane Vacuum Pump is running continuously, the vacuum curve is stable and does not fluctuate easily, making it ideal for production processes that require high vacuum consistency, such as:

Vacuum packaging

Vacuum adsorption and handling

Molding and shaping processes

Vacuum drying and degassing

Whether used as a standalone unit or as part of a vacuum system, it can operate stably without causing any problems.

Oil, in this pump, is not simply a lubricant, but one of the core components of its performance.

Efficient sealing: Vacuum oil fills tiny gaps, improving the ultimate vacuum

Reduced wear: Reduces direct metal contact, extending service life

Auxiliary heat dissipation: Keeps the pump body at a reasonable temperature during long-term operation

We have optimized the oil circuit design and material matching to make the vacuum oil last longer, stay cleaner, and be more stable, reducing maintenance costs associated with frequent replacements.

This is not a device that needs to be replaced after one or two years, but an industrial product designed for long-term operation.

Core components are wear-resistant and durable

Clear maintenance structure, easy to disassemble and assemble

High interchangeability of wear parts, making future replacements easier
