rotary vane vacuum pump with singel stage for food packages

Rotary vane vacuum pumps are reliable, efficient, and versatile vacuum solutions engineered for a wide range of industrial applications. With precision construction and a compact design, they provide stable long-term performance in chemical, food, pharmaceutical, semiconductor, laboratory, and automotive industries.

Features of Rotary Vane Vacuum Pumps

• Power range: 0.55 to 18.5 kW
• Pumping rate: 16 to 750 m³/h
• Pressure range: 0.5 to 1 mbar
• Single-stage design: Simple, efficient operation for low and medium vacuum pumping
• Reliability: Precision-engineered for long-term, stable operation
• Wide suitability: Ideal for various industrial environments

How Rotary Vane Vacuum Pumps Work

The pump consists of a cylindrical pump body, eccentrically mounted cylindrical rotor, rotary vanes supported by springs, end cover, and exhaust valve. As the rotor spins, the vanes maintain contact with the inner wall of the pump chamber, compressing gas and discharging it through the exhaust valve to create a vacuum. The oil film between the pump body and rotor provides necessary sealing to prevent gas leakage, ensuring stable pressure during operation.

Performance Advantages

1. Energy saving & environmental protection: High efficiency, low energy consumption, and clean exhaust in line with environmental standards.
2. Easy operation & maintenance: Simple structure allows for quick, routine maintenance.
3. Compact design: Small footprint for easy integration and installation.
4. Air-cooled: No need for external cooling systems; stable operation with air cooling alone.
5. Low noise & vibration: Smooth, quiet performance for noise-sensitive environments.
6. High durability: Built from quality materials for continuous, long-term operation.
7. Flexible transmission: Direct drive in small/medium models, belt drive for high flow, supporting various configurations.
