Vacuum Screw pumps RVS + SCREW Technology

RVS + SCREW vacuum screw pumps are essential equipment for achieving deep, stable vacuum levels in industrial and chemical processes. Their dry-running operation and non-contact internal design ensure clean and safe performance, even in demanding applications. With progressive compression technology and excellent thermal control, they deliver efficiency, reliability and long-term durability in sectors where vacuum quality is critical. 
  • Max Vacuum 1.5x10-2 Torr 
  • No cooling gas up to 800 m³/h necessary  

RVS + SCREW vacuum screw pumps operate through the progressive compression of gas using a variable-pitch screw and synchronized rotors that never make contact. As the gas moves through the chamber, its volume is reduced in a controlled way, generating a stable, efficient vacuum without the need for internal lubrication. This design allows lower operating temperatures and ensures consistent performance during long duty cycles.

  • Progressive vs Conventional Compression: The variable-pitch screw enhances internal sealing and improves energy efficiency.
  • Dry Operation vs Lubricated Systems: With no oil inside the chamber, it prevents process contamination and reduces maintenance needs.

RVS + SCREW vacuum screw pumps offer efficiency, reliability and safety for demanding industrial applications. Their dry-running operation, progressive compression and non-contact rotor design make them an ideal solution where vacuum stability and thermal control are critical.

  • High Energy Efficiency: Progressive compression lowers power consumption and ensures stable performance during long cycles.
  • Dry Operation: No oil inside the compression chamber, ensuring cleaner processes and eliminating contamination risks.
  • Low Noise and Vibration: Non-contact rotor design minimizes vibration and results in quieter operation.
  • Advanced Thermal Control: Reduced heat generation prevents overloads and enhances process safety.
  • Reduced Maintenance: Lower wear and a robust construction extend the equipment’s lifespan.

RVS + SCREW vacuum screw pumps are essential across many industrial sectors, providing deep, stable and contamination-free vacuum conditions. Their dry-running design and controlled temperature operation make them ideal for demanding processes that require reliability and safety.

  • Chemical and Petrochemical Industry: Distillation, degassing and handling of sensitive gases without contamination risk.
  • Pharmaceutical and Biotechnology: Vacuum drying, lyophilization and production under strict purity requirements.
  • Metallurgy and Steel Plants: Vacuum degassing and thermal treatments requiring deep and stable vacuum levels.
  • Laboratories and Research: Analytical equipment, vacuum chambers and high-precision scientific applications.
  • Plastics and Composites Manufacturing: Extrusion, polymer degassing and quality control using stable vacuum conditions.

Choosing the right RVS + SCREW pump requires evaluating the specific needs of each process to ensure efficient, safe and long-lasting performance. Correctly assessing the technical requirements guarantees the vacuum level, stability and reliability necessary for industrial applications.

  • Flow Rate and Vacuum Level: Define the capacity required for each application.
  • Energy Efficiency: Choose models that minimize consumption and operating costs.
  • Gas Type and Process Conditions: Ensure compatibility with temperature and gas properties.
  • ATEX Safety Requirements: Select certified equipment for explosive environments.

To ensure optimal performance and extend the service life of RVS + SCREW pumps, simple and consistent maintenance practices are essential.

  • Regular Inspections: Check temperatures, gears and overall equipment condition.
  • Vibration and Noise Control: Identify early signs of misalignment or wear.
  • Cooling System Monitoring: Ensure the thermal circuit operates correctly.
  • Preventive Maintenance: Schedule reviews to reduce downtime and maintain vacuum stability.

What is a vacuum screw pump used for?

It is used to generate deep, stable vacuum in chemical, pharmaceutical, metallurgical and laboratory processes where clean, safe and contamination-free operation is required.

What vacuum level can they achieve?

They can reach deep vacuum levels suitable for advanced degassing, drying and sensitive gas handling, maintaining stability during long operating cycles.

What maintenance do they require?

Mainly periodic inspections, temperature checks, vibration monitoring and preventive servicing, as the non-contact design minimizes internal wear.

Are they suitable for sensitive or corrosive gases?

Yes, their dry-running design and sealed configuration allow safe handling of complex gases, provided compatibility is verified and ATEX-certified setups are used when required.
