Oil-lubricated vacuum pumps are used in high-level vacuum operations and are designed to work with oil circulation. They are typically adapted for systems requiring high air evacuation, precise vacuum, or centralized vacuum systems.

Working Principle:

The rotor spins inside a fixed stator via centrifugal force, and fiberglass-reinforced vanes on the rotor sweep the stator, self-lubricating to create vacuum.

• Wide industrial use in oil-circulated vacuum pumps.
• Manufacturing of electric lamps, vacuum tubes, and processes requiring vacuum and gas injection.
• Medical applications requiring vacuum aspiration.
• High-vacuum needs in electron microscopy.
• Vacuum coating for energy savings, durability, and decoration.
• Hard-layer coatings (e.g., Formula 1 vehicles).
• Boat and yacht construction.
• Oil refining plants.
• Sterile environments (hospitals, etc.).
• Plastic and leather molding.
• Workpiece clamping in CNC routers.
• MDF lamination in furniture (membrane pressing).
• Food vacuum packaging.
• Production of paper, plastic, rubber, wood, glass, marble, ceramics, gold, etc.
• Chemical, medical, and cosmetic products.
• General use in mechanical, metallurgical, and electromechanical industries.

Also used in centralized vacuum systems for:

• Hospitals and dental clinics.
• Laboratories.
• Printing and packaging facilities.
• Composite material production.
• General manufacturing areas.

These pumps are easy to operate and maintain, with a design that minimizes spare part needs. Spare parts are highly economical.

• Designed for high and precise vacuum.
• Long maintenance intervals.
• Low maintenance costs.
• Maximum vacuum: 0.5–2 mbar (758–759 mmHg).

• Only allow dry air passage.
• Require daily maintenance monitoring.
