5.5kW Intelligent Screw VFD Vacuum Pump With 390m3/H Pumping Speed

When industrial production lines, packaging systems, molding machines and central vacuum systems require stable, high-efficiency and energy-saving vacuum supply, the Bebaios RV Series Oil-Sealed Rotary Screw Vacuum Pump delivers consistent performance. Designed for heavy-duty industrial environments, this pump series integrates premium screw rotor technology, intelligent variable frequency control and direct-drive transmission to maintain reliable vacuum output while drastically reducing energy consumption and operating noise.

The RV series covers power from 2.2kW to 90kW, with pumping speeds from 70m³/h up to 5400m³/h and ultimate pressure down to 0.35mbar. All units run on 380V 50/60Hz power and adopt variable frequency starting for smooth, energy-efficient operation.

• Up to 50% Energy Saving

  Equipped with advanced variable frequency technology, the RV series accurately adjusts vacuum pressure and flow based on real-time demand. Within a wide operating range (10%–100%), it saves an average of 50% energy compared to conventional vacuum pumps. The rigid direct-drive structure delivers 100% transmission efficiency, saving an extra 5% energy over belt-driven units and eliminating belt maintenance costs.

• Stable, Durable & Low Noise

  The pump features a large rotor, low-speed design that reduces wear, vibration and noise. High-grade bearings and patented rotor profiles ensure stable performance and long service life. The multi-duct cooling system and optimized structure lower noise to below 72dB(A), enabling reliable continuous operation.

• High Oil-Retention & Clean Exhaust

  The two-stage high-efficiency oil separator minimizes fluid carry-over, ensuring clean exhaust air and protecting downstream equipment. Excellent oil retention reduces environmental impact and lowers operating costs for oil replacement.

• Smart Control & Unattended Operation

  The intelligent microcomputer controller provides real-time monitoring, overload protection, over-temperature shutdown, delay protection and automatic fault diagnosis. Users can check operating data on computers or mobile phones via the IoT cloud platform, supporting remote diagnosis, equipment lifecycle management and data analysis.

• Easy Installation & Low Maintenance

  The integrated, compact structure enables plug-and-play installation. Cassette-type filter elements allow quick, tool-free replacement. The intake control valve automatically adjusts vacuum flow to avoid frequent load/unload cycles, further reducing maintenance and operating costs.
